The species name derives from the Latin armatus (protected), referring to the armament of colony provided by numerous kenozooidal spines. Description. Colony erect, branching, flexible, with numerous strap-shaped to flabellate lobes, rounded and undulate at growing margins (Fig. 2 A, B); up to 12.5 cm in height, but usually 6.5–8.5 cm; attached to substratum by encrusting, unilaminar basal plate, up to 1.4 x 2.2 cm in size. Up to 7 closely appressed stalks arranged in parallel planes can arise from single basal plate (Fig. 2 B). Branches of independent trunks mutually interlaced, giving bushy appearance to colony. Young colonies are yellowish, grayish, or pale brown, with whitish zone comprising 3–5 generations of developing zooids on periphery of terminal branches. Mature colonies brownish to flesh-coloured, with dark-brown to reddish fringing zone of marginal kenozooids along entire periphery, except for stalk. Branches slender, 5–17 mm wide, 1.1–1.8 mm thick (without spines). Lobes bilamellar without interposed medullary kenozooidal layer. Zooids oval to rounded-rectangular, elongate, arranged alternately in distinct series. Grooves distinct between young zooids, when not occupied by kenozooids (Fig. 4 A). Frontal surface smooth, inflated, semitransparent, yellowish to brownish, chitinous. Orifice (Fig. 4 B) subterminal, raised, transversely elongate, bilabiate, roughly oval to rectangular in outline, with thickened, chitinous proximal labium, brown in color. Along each lateral zooidal margin are small kenozooids with circular to oval base and a sharp simple spine directed upwards or slightly tilted toward zooid. Young zooids (Fig. 4 A, B) have 1–2 pairs of distal kenozooids, each with a sharp spine pointing upwards, flanking orifice; 1–3 similar kenozooids successively developing more proximally along each lateral margin (Fig. 4 C, D). Zooids in mature colony regions (Fig. 4 E, F) interspersed with single or double series of 4–6 kenozooids each, with parallel or alternating arrangement and with pointed, straight or slightly tilted spines; in addition, there are 1–3 small kenozooids, each with a minute, slightly curved spine, between maternal and daughter zooids. Thus, old zooids can be entirely surrounded by small kenozooids. With age and increasing chitinization, all kenozooidal spines acquire a dark-brown color that contrasts with the zooidal surface. Large vicarious kenozooids scattered throughout colony, these oval, hexagonal, or rhombic in shape with strongly convex frontal surface (Fig. 3 B); occasionally arranged as compact groups in limited areas on colony surface (Fig. 3 A). A hollow, tubular spine (Fig. 3 A–C, F, G), dark brown in color, sharply contrasting with brownish colony surface, originates from center of each vicarious kenozooid. Spines straight to slightly curved in middle, orientated vertically or tilted slightly distally or distolaterally. Majority of spines weakly branching terminally into 2–5 short spurs, without secondary branches; some lack distinct ramifications and have a slightly pointed or blunt tip. Most spines gradually taper from base to tip, but some are enlarged in middle and appear spindle-shaped; others are entirely elongate-cylindrical. Occasionally, a spine narrows moderately in middle and is secondary enlarged near tip, at point of ramification. Bases of large kenozooids flanked by 2–5 minute kenozooids along each lateral margin, each with short, pointed spine directed laterally and upwards. Marginal kenozooids very irregular in shape and size, arranged along entire lateral and terminal margins of branches (Fig. 3 D–F). At terminal end of growing branches, kenozooids fringe the zone of developing zooids (Fig. 3 B). Along margins, kenozooids of opposite layers develop complementarily, side by side (Fig. 3 D), and partly overlap each other; each has a conical spine with pointed tip, oriented 20–80 ° from frontal plane. Encrusting basal plate and stalk of colony (Fig. 4 G, H) composed entirely of inflated kenozooids that are hexagonal, oval, roughly quadrangular, or irregular in shape, with distinct raised boundaries, not intercalated with small, spinous kenozooids. Polypide with 18 tentacles. Measurements. ZL, 0.62–1.03 (0.81 ± 0.09). ZW, 0.32–0.51 (0.39 ± 0.05). OrL, 0.14–0.23 (0.18 ± 0.02). OrW, 0.27–0.35 (0.31 ± 0.02). Kz(s)L, 0.05–0.20 (0.12 ± 0.04).

Flustrellidra armata most resembles its Japanese congener F. stolonifera (Okada, 1921) in having a similar erect, branching, strap-shaped colony form; zooids interspersed by small lateral kenozooids with sharp, simple spines; and very large vicarious kenozooids bearing tubular branching spines. However, F. armata differs from the latter in the following combination of characters: (1) the number of minute, spiny kenozooids separating neighboring zooids along the lateral margins successively increases in F. a r m a t a with age from one or two to five or six, whereas F. stolonifera has only one pair of angular kenozooids flanking the orifice, and rarely one additional pair proximolaterally; (2) the double series of kenozooids between zooids in mature regions of the F. a r m a t a colony is absent in F. stolonifera; (3) the proximal kenozooids that separate maternal and daughter zooids of F. a r m a t a have not been reported in F. stolonifera; (4) branch margins of F. armata are fringed along their whole length with marginal kenozooids having a conical spines, while the margins are edged with spineless zooids in F. stolonifera; (5) spines of the vicarious kenozooids of F. a r m a t a are scarcely branched and only at the very tip, without secondary ramification, whereas the homologous spines in F. stolonifera are divided into two to six tine-like branches (see Okada 1921, text-fig. 1; Mawatari 1953, text-fig. 3). An eastern-Pacific species, F. s p i n i f e r a (O’Donoghue & O’Donoghue, 1923), also forms erect colonies, having strap-shaped bilamellar lobes and large kenozooids with long, sparsely branched spines (holotype specimen illustrated by d’Hondt 1983, pls 1, 2), some of which are superficially similar to those in F. a r m a t a. However, the spine branches are always longer and the ramification is deeper than in the vicarious kenozooidal spines of F. armata. In addition, all kenozooids of F. spinifera are of the same type, located distally to each zooid, whereas in F. a r m a t a large vicarious kenozooids are scattered over the colony surface and small, circular kenozooids with a simple spine are always present. Ecology. The majority of colonies of F. a r m a t a collected intertidally support a diverse association of other sessile benthic forms. Most colonies observed were covered with hydroids, sponges, tubes of sabellid polychaetes, barnacles, ascidians, brachiopods, green and red algae (including articulate coralline algae), and other bryozoans, including species of Lichenopora, Alcyonidium, Cauloramphus, Figularia, Hippothoa, Watersipora, Fenestrulina, Microporella, Pacificincola, Celleporaria, and Celleporina. Among the bryozoans, colonies of Celleporaria were the most frequent and abundant, forming thick nodules around the branch stems of F. a r m a t a. Occasionally, errant polychaetes, pycnogonids, and the shells of juvenile gastropods and oysters were noticed between the appressed branch trunks of colonies. We observed in the field that populations of F. a r m a t a are patchy in the upper subtidal zone but have a high of coverage of substrata on rocky bottoms at depths of 10–20 m at some sites. These deeper colonies likewise provide a habitat for a variety of subtidal benthic organisms. We saw dozens of caprellid and other amphipod crustaceans associated with colonies of F. a r m a t a. The majority of colonies were densely covered by hydroids, green and red algae (both encrusting and articulate coralline algae), sponges, barnacles, tubes of sabellid polychaetes, and other bryozoans, including species of Crisia, Lichenopora, Alcyonidium, Cellaria, Beania, Catenicella, Escharoides, Pacificincola, Celleporaria, and Celleporina. In some cases, we found juvenile mytilids, oysters, decapods, errant polychaetes, and pycnogonids between branches of of F. a r m a t a colonies, and groups of small scleractinians attached to the basal region of colonies. Distribution. Flustrellidra armata is currently known along more than 300 km of the southern shoreline of the Korean Peninsula, facing the western passage of the Korea Strait, between Mipo (35 ° 36 ’ N, 129 ° 27 ’ E) in the northeast and Mokdo (34 ° 10 ’ N, 126 ° 34 ’ E) in the southwest. Accordingly, F. a r m a t a can be categorized as a Pacific-Asian, low-Boreal to Subtropical, intertidal to upper-subtidal species.Published as part of Grischenko, Andrei V., Seo, Ji Eun & Min, Bum Sik, 2010, Flustrellidra armata (Bryozoa: Ctenostomatida) — a new species from the southern shoreline of Korea, pp. 25-35 in Zootaxa 2684 on pages 27-32, DOI: 10.5281/zenodo.19941
Search Engine Optimisation in UK news production
No full textThis is an Author's Accepted Manuscript of an article published in Journalism Practice, 5(4), 462 - 477, 2011, copyright Taylor & Francis, available online at: http://www.tandfonline.com/10.1080/17512786.2010.551020.This paper represents an exploratory study into an emerging culture in UK online newsrooms—the practice of Search Engine Optimisation (SEO), which assesses its impact on news production. Comprising a short-term participant observational case study at a national online news publisher, and a series of semi-structured, in-depth interviews with SEO professionals at three further UK media organisations, the author sets out to establish how SEO is operationalised in the newsroom, and what consequences these practices have for online news production. SEO practice is found to be varied and application is not universal. Not all UK news organisations are making the most of SEO even though some publishers take a highly sophisticated approach. Efforts are constrained by time, resources and management support, as well as off-page technical issues. SEO policy is found, in some cases, to inform editorial policy, but there is resistance to the principal of SEO driving decision-making. Several themes are established which call for further research

No full text학위논문(석사)--아주대학교 일반대학원 :심리학과,2007.2본 연구는 가장 친밀한 대인관계 중 하나인 부부를 대상으로 이들의 용서가 자기 자신 그리고 상대방의 결혼만족에 미치는 영향을 Kenny(1996)가 제안한 Actor-PartnerInterdependence Model(자기-상대방 상호의존성 모델:APIM)에 근거하여 검증하였다.총 215쌍의 부부자료가 분석되었고,용서질문지,결혼만족 질문지,신경증 질문지가 사용되었다.
용서는 상처 입은 사람이 가해자와의 관계에서 취할 수 있는 복합적인 심리 반응이다.용서를 경험과학적으로 연구하는 최근 흐름과 더불어 용서가 상담 및 교육장면에서도 상처받은 마음을 치유하기 위해 사용되는 예가 증가하고 있다. 하지만 기존 연구들은 용서가 결혼만족에 미치는 개인 내적 과정에만 초점을 두고 있다.부부는 장시간 상호작용이 많고 그들이 만나기 전부터 여러 특성에서 유사할 가능성이 크기 때문에 이들의 자료는 비독립적인 성질을 갖는다.이러한 비독립적인 성질을 충분히 고려한 분석방법을 사용할 때 부부의 대인 간 영향과 개인 내 영향을 동시에 살펴볼 수 있다.APIM은 부부 특성이 그 자신에게 미치는 효과(자기효과)와 상대방에게 미치는 효과(상대방효과)를 동시에 추정할 수 있게 해주기 때문에,부부와 같이 상호의존성이 존재하는 짝 자료의 예측적 관계를 검증할 때 이용하는 데 적합한 분석방법이다.
본 연구는 APIM을 적용하여 용서가 결혼만족에 갖는 영향을 개인 내 효과와 대인 간 효과로 나누어 그 의미를 알아보았다.그리고 개인 내 효과들 간 비교와 대인 간 효과들 간 비교를 통해 성별에 따른 차이를 확인하였다.효과 크기간의 상대적 비교는 구조방정식에서 등가제약 설정을 통해 이루어졌다.다음으로 기존 연구들에서 결혼만족과 강한 상관이 있는 것으로 알려진 신경증과 연령을 공변인으로 한 통제 분석을 하였다.통제 분석은 다른 변인의 영향을 통제하고서도 여전히 용서가 결혼만족에 미치는 영향이 유의미한지 알아보기 위한 것이다.마지막으로 남편의 용서와 부인의 용서가 서로 상호작용하여 결혼만족을 증가시키는 효과를 갖는지 알아보기 위해 상호작용효과를 검증하였다.
연구 결과,부부에게 용서는 각자 자신의 결혼만족에 대하여 유의미한 예측변인임이 밝혀졌다.이와 더불어 부인의 용서는 상대방인 남편의 결혼만족을 예측하였다.즉,용서가 높을수록 그 자신의 결혼만족이 높았으며,특히 부인 용서가 높은 경우 그 남편의 결혼만족도 높게 나타났다.용서가 결혼만족에 미치는 개인내 효과와 대인 간 효과들을 비교하기 위해서 각 효과들 간 비교를 한 결과,결혼만족에 대한 용서의 영향은 상대방이 미치는 영향보다 자신이 미치는 영향이 더 큰 것으로 나타났다.또한 결혼만족에 대한 용서의 영향은 남편보다 부인에게 더 크게 나타났다.통제 분석에서 용서는 신경증을 공변인으로 통제한 후에도 여전히 결혼만족에 유의미한 영향을 미치고 있었다.남편과 부인 용서의 상호작용 효과는 나타나지 않았다.이는 용서가 반드시 상호적 과정에 의해 이루어지는 것은 아님을 나타낸다.본 연구는 부부의 결혼만족에 용서가 미치는 효과를 자기효과와 상대방효과로 나누어,이들 효과 간 비교를 통해 개인 내적 과정 뿐 아니라 대인 간 과정에 대한 정보를 제공한다.마지막으로 이러한 결과를 바탕으로 본 연구의 시사점과 제한점에 관해 논하였다.Ⅰ. 서론 = 1

Abstract = 64MasterThis study examined effects of forgiveness on marital satisfaction. For analysis of data from the married couple, Actor-Partner Interdependence Model by Kenny(1996) is applied to this study. Main effect(actor-partner effect)s of forgiveness were estimated from APIM. Then in order to compare relative sizes of the paths from the variable to husband and wife outcome score, a procedure of setting equality constraints were conducted in Structural Equation Modeling.
Results suggests that forgiveness was a significant positive predictor of marital satisfaction for each spouse. Additionally, wife's forgiveness predicted husband's satisfaction. Actor effects were contributed to self-marital satisfaction than partner effects. Effects of forgiveness were also significant in case controlling neuroticism and age variable in model. Control analysis indicated that forgiveness was important predictor on marital satisfaction after controlling other predictors. Finally, interaction effect of forgiveness was examined in order to learn that husband's forgiveness and wife's forgiveness make marital satisfaction increase.
This study divides the effect of forgiveness on marital satisfaction into actor and partner effects. The study provides us with interpersonal process aspect as well as intrapersonal process aspect of forgiveness and marital satisfaction. In comparison with them, findings indicated that there is sex difference in the intrapersonal and interpersonal process of forgiveness and marital satisfaction. Interaction effect result show that synergistic interaction of husbands' and wives' forgiveness did not predict their satisfaction. It reflect that forgiveness may not be reciprocal process. In conclusion, the consequence suggested the issue and the limitation on the study
Effectief prijs- en mededingingsbeleid in Caribisch Nederland: advies aan het Bestuurscollege van het Openbaar Lichaam Bonaire
No full textIn opdracht van het Bestuurscollege van Bonaire, heeft SEO onderzoek gedaan naar, en geadviseerd over prijs- en mededingingsbeleid op Bonaire. SEO adviseert voorzichtig te zijn met het instrument prijsbeleid omdat dit het achterliggende probleem van gebrek aan concurrentie niet oplost. Prijsbeleid kan hooguit dienen als tijdelijke, korte termijn maatregel en dient zo min mogelijk in te grijpen in de keuzevrijheid van de ondernemer, een prikkelstructuur te hebben dat effectieve marktwerking nabootst en de uitvoerings- en handhavingslasten laag te houden. SEO adviseert het bestuurscollege om met Nederland tegelijkertijd te werken aan de invoering van een mededingingswet op Bonaire met onafhankelijk toezicht. Omdat de economie van Bonaire vervlochten is met die van Curacao (en Aruba), is het aanbevelenswaardig om in de ontwikkeling en de uitvoering van mededingingsbeleid, aansluiting te zoeken bij het mededingingsbeleid dat op Curacao en Aruba ontwikkeld wordt

Arthropoma n. sp.: Hirose 2010: 111, pl. 190A–C. Material examined. Holotype: MBRBKSP033, 34.5366° N, 128.7314° E, Hong Island (Hongdo), Gyeongsang Province, collected 1 June 1987 by J.E. Seo and J.G. Je. Paratype: MBRBKSP034, 34.4292° N, 127.2280° E, Dok Island (Dokdo), South Jeolla Province, collected 24 June 2008 by J.E. Seo, B.S. Min and H.J. Yang, 10– 15 m. Other material: Woosuk University Collection—specimens from Chuja Islands, Daepo, Gapa Island, Gu Island, Mijo, Moseulpo and Seogwipo, collected by J.E. Seo, H.J. Kil and J.H. Yoo. Etymology. Latin magnus, large, and porosus, full of holes (Brown 1956), alluding to the relatively large size and distribution of the pseudopores. Arthropoma is neuter in gender, hence the species epithet is also neuter. Description. Colony encrusting, unilaminar, up to 20 mm in diameter. Zooids regularly quincuncial, the distal margin rounded or angular, more rarely truncated, the lateral margins more or less parallel-sided in many zooids. Orifice proportionately large, the anter high-arched, curving proximally to horizontal ‘shoulders’ that bear thin condylar surfaces that project slightly across the entrance to the small U-shaped sinus, constricting it. Operculum with jointed sinus tab. Frontal shield convex, perforated by c. 35–46 relatively large, round pseudopores that are distributed over the most of the surface in the majority of zooids, except for an irregular, smooth narrow area midfrontally that is subumbonate or weakly carina-like in some zooids. Additional pseudopores are distributed around the orifice in an arc of 10–19 pores in an inner series, sometimes with a few other pores in an incomplete second series. No oral spines. No avicularia. Ooecium prominent, hyperstomial, apparently cleithral (subcleithral), with the zooidal operculum able to close both the ooecial orifice and the lower zooidal orifice; ooecial orifice nearly at right angles to the maternal zooidal orifice. Ectooecium wholly membranous except for a thin peripheral rim around the base; endooecium minutely and densely pitted and textured, the pits less obvious frontally. Multiporous mural septula present in lateral and distal walls. Ancestrula not seen. Measurements. ZL 480–636 (540) µm, ZW 287–403 (360) µm; OL 165–197 (177) µm, OW 134–175 (158) µm; OoL 223–310 (277) µm, OoW 295–371 (342) µm. Remarks. Arthropoma magniporosum n. sp. has in the past been identified as Arthropoma cecilii Audouin, 1826, a species from the Mediterranean/ Red Sea that has been accorded a wide distribution in cool-temperate to warm-temperate and tropical waters of the Atlantic and Indo-Pacific, from 25–1235 m depth (summarized by Dick & Grischenko 2017). If the species illustrated by Hayward & Ryland (1999) were to be taken as representing the species in the absence of actual type material, then it differs from A. magniporosum in several features. For example, A. cecilii has more than twice the number of frontal-shield pseudopores (c. 120–130), which are accordingly smaller and denser than in A. magniporosum. The ooecium of A. cecilii has a smoothly calcified rim around the orifice, with a mid-distal extension, and the sides of the ooecium taper more closely towards to proximal orificial rim than in A. magniporosum. Dick & Grischenko’s (2017) illustration of A. cecilii from the Mediterranean Sea area of Marseille resembles that of Hayward & Ryland (1999) from Britain (presumed, but not stated as such), but has fewer frontal-shield pores (81–96), and there are minor differences in frontal ectooecial sculpturing and placement of the proximolateral corners of the ooecium. Their conspecificity is uncertain. In either case, whether from the Mediterranean or elsewhere, the material from Europe is not the same as A. magniporosum n. sp. It is likely that A. cecilii was originally illustrated and described from Red Sea specimens (at least in part), but, in the absence of type specimens, no further conclusions can be drawn; Savigny’s drawings (d’Hondt 2006, pp. 31, 60) are inconclusive. The synonymy given above does not cite all records of A. cecilii in the northeast Asian region, only those that definitely or almost certainly refer to A. magniporosum n. sp. The record of Okada & Mawatari (1936) is included as the authors stated that their unillustrated specimen from Hatsushima, Sagami Bay, Japan, had “very larger tremopores than the normal form”. Only a few other Recent species of Arthropoma have been described. Arthropoma inarmata Gontar, 1992 from the Kurile Islands differs in having only 21–26 pseudopores in the proportionately short frontal shield, while there is a complete double row of pores in the relatively broad area distal to the orifice. Additionally, Gontar (1992) mentioned that the pores have a radial structure, which would be exceptional among Arthropoma species, suggesting that Cribellopora Gautier, 1957 might be a more appropriate genus to accommodate A. inarmata. Arthropoma lioneli Florence, 2016 from South Africa has distinctive reniform pores. A new species from the west coast of Okinawa (Dick & Grischenko 2017) (East China Sea) has a crescentic suboral umbo that sometimes contributes to a continuous peristomial rim. As Dick & Grischenko (2017) point out, three species, none of them A. cecilii, are illustrated by Hirose (2010) from Japan. One of them corresponds to A. magniporosum n. sp. (see synonymy above). A second (Hirose 2010, pl. 189A, B) corresponds to Arthropoma mediolaevis (Ortmann, 1890). He described the taxon as a ‘variety’ of cecilii, noting that it differed in the “Glattes Feld in der Mitte der Zelle grosser”, i.e. the smooth field in the center of the zooid is greater than in cecilii. The sinus is also very narrow and the pseudopores are very small. The third species, presently undescribed (Hirose’s 2010, fig. 189C, D), differs again in having an almost subcircular sinus and in the small pseudopores occupying the entire frontal shield, or nearly so. Further, this species has a dimorphic zooid with a large orifice and a few distal-oral spines. The proportions of the dimorphic orifice differ from those illustrated by Kirkpatrick (1890) from the South China Sea, and Harmer (1957) from Indonesia, indicating that additional forms need naming as new species. Yet another unnamed species occurs in the Sagami Bay region; this was illustrated by Grischenko & Mawatari (2006, fig. 1G) as A. cecilii, but it differs from all of the forms mentioned above in having a smooth non-pitted endooecium and 3–4 rows of pseudopores between the maternal orifice and developing ooecium. Based on ooecial morphology, and using the terminology of Ostrovsky (2013, pp. 130, 131), the ooecium appears to be the subcleithral form of a cleithral orifice, i.e. having two potential operculum closure positions, with the lower position closing the zooidal orifice. Observations on living material would be required to confirm if this is the case. It is known that the sinus tab of the operculum is hinged, as reflected in the genus name; if and when the operculum closes the ooecial orifice, the sinus tab is almost at right angles to the porta (rest of operculum).

Monitor jonge fiscalisten 2009
No full textDe arbeidsmarktpositie van pas afgestudeerde fiscalisten is al jaren krap. De Nederlandse Orde van Belastingadviseurs (NOB) heeft daarom behoefte aan zicht op de arbeidsmarktpositie van hoogopgeleide fiscalisten die pas het onderwijs hebben verlaten. SEO Economisch Onderzoek voert in opdracht van de NOB een jaarlijks onderzoek uit waarin die arbeidsmarkt wordt geschetst. In het laatste onderzoek, uit 2008, kwam wederom naar voren dat de arbeidsmarktvooruitzichten van fiscalisten buitengewoon goed zijn. Dit rapport kijkt naar de situatie anno 2009. In tegenstelling tot het onderzoek van 2008 is dit jaar ook de vraagzijde onderwerp van onderzoek. Directe aanleiding voor deze toevoeging vormt het uitbreken van de economische crisis in de loop van 2008. Dat kan gevolgen hebben voor de vraag naar fiscaal personeel. De arbeidsmarktpositie van fiscalisten is nog steeds goed tot zeer goed te noemen. De in- en uitstroom van fiscaal personeel blijft bij de grotere kantoren naar eigen zeggen dan ook min of meer gelijk. Ook in de nabije toekomst verwachten ze daarin geen verandering, net als de fiscalisten zelf. Bijna alle pas afgestudeerde fiscalisten geven aan geen angst te hebben om komend jaar hun baan te verliezen. De komende editie van de monitor zal aantonen of dit optimisme terecht is
Investigating the jet activity accompanying the production at the LHC of a massive scalar particle decaying into photons
No full textWe study the jet activity that accompanies the production by gluon fusion of a new physics scalar particle decaying into photons at the LHC. In the considered scenarios, both the production and decay mechanisms are governed by loop-induced interactions involving a heavy colored state. We show that the presence of large new physics contributions to the inclusive diphoton invariant-mass spectrum always implies a significant production rate of non-standard diphoton events containing extra hard jets. We investigate the existence of possible handles that could provide a way to obtain information on the underlying physics behind the scalar resonance, and this in a wide mass window. © 2016 The Author(s)4411Nsciescopu
Exochella cryptodontia Min, Seo, Grischenko & Gordon, 2017, n. sp.
No full textExochella cryptodontia n. sp. (Figs 24–26) Etymology. The species name alludes to the cryptic, minutely toothed proximal margin of the primary orifice (Greek odon, tooth). Material examined. Holotype: NIBRIV0000325941, Hwadong, Baengnyeong Island, 37.9192° N, 124.7002° E, southeastern coast, 24 November 2007, low tide, collected by B.S. Min and A.V. Grischenko. Paratype: NIBRIV0000711264, Dumujin, 37.9738° N, 124.6170° E, northwestern coast, 25 November 2007, low tide, collected by B.S. Min and A.V. Grischenko. Other material: Woosuk University collection—Baengnyeong Island: Hwadong (47 colonies), Junghwadong (3 colonies), Dumujin (106 colonies), Jinchon-ri (7 colonies), Gobongpo (8 colonies), Yeonhwa-ri (23 colonies); mostly on rocky substrata, but also on plastic debris, shell and crustose coralline algae (Clathromorphum). Cheongsan Island (1 colony) on a small rock. Description. Colony encrusting, unilaminar, small, to 40 mm in diameter. Autozooids at growing margin subhexagonal, with the angles rounded distally and proximally, and acute laterally; the overall shape less angular in older autozooids with heterozooids; arranged regularly in quincunx. Umbonuloid frontal shield not very convex, more or less smooth, with 5–7 conspicuous areolar pores along each margin. Primary orifice deep-set, proximal rim bearing 9–10 minute peg-like teeth along the proximal rim as seen from interior view. Oral spines usually 3, sometimes 4, on the distal rim of marginal zooids, proximal of which is a peristome that surrounds the rest of the orifice; middle part of peristome forming a bridge, creating a relatively large pseudospiramen, at the bottom of which the almost-concealed, minutely toothed border is just visible proximally; proximal margin of peristomial rim high, somewhat spout-like, sloping steeply to frontal shield. Oral spine bases mostly completely concealed in older or ovicellate zooids, although sometimes one can be seen adjacent to an avicularian rostrum projecting from a neighboring zooid. Avicularia paired or single, each budded from an areolar pore at widest part of zooid, the acute rostrum directed more or less laterally or slightly obliquely proximolaterally, the palatal foramen and avicularian opesia relatively large, separated by a complete crossbar. Ooecium recumbent on distal zooid, occupying much of its frontal shield, convex, smooth, subumbonate, forming a low arcuate rim around the distal margin of the maternal orifice, opening above secondary orifice. A pair of basal pore-chambers present in distal half of each zooid, with 1–2 mid-distally. Ancestrula not seen. Measurements. ZL, 276–427 (333) µm; ZW, 152–295 (235) µm; OrL, 80–91 (84) µm; OrW, 87–112 (99) µm; AvL, 75–101 (91) µm; AvW, 37–53 (45) µm; OoL, 142–169 (153) µm; Oo,W 149–180 (164) µm. Remarks. We found E. cryptodontia n. sp. not only at Baengnyeong Island but also at deeper localities (27–42 m) among the islands of the southwestern coast of South Korea. In both areas the species is relatively common and abundant, so it is surprising that it appears not to have been previously encountered. Four species names have been applied to Recent Exochella from northeast Asia and a median pseudospiramen is lacking in all four. Two of them are endemic to the region. These are Exochella japonica Ortmann, 1890, which has a median peristomial process flanked by a pair of pseudosinuses and what may be lateral linear ridges on the ooecium, and Exochella areolata Okada & Mawatari, 1937, which also has a median process, but this is not flanked by pseudosinuses (cf. Kubanin 1975). The other two species names— Exochella tricuspis (Hincks, 1881) and Exochella longirostris Jullien, 1888 —pertain to taxa first described from Bass Strait, Australia and Magellanic South America, respectively. Published illustrations of these species (not all using SEM) from the northeast Asian region (e.g. Mawatari 1965; Rho & Lee 1980; Seo & Min 2009) certainly closely resemble those based on topotypic material but subtle differences are evident. Since neither of these species has been noted as hull-fouling or invasive, it is possible, if not likely, that populations from northeast Asia may not be conspecific. Close comparison of Asian material from Asia and austral regions using SEM needs to be carried out. One useful character is the internal configuration of orificial structures, such as depicted by Levinsen (1909) and Gordon (1989). A fifth form from northeast Asia is Exochella longirostris var. quadricella Sakakura, 1935 from the Pleistocene Dizodo beds of Boso Peninsula, Honshu, Japan. Sakakura noted that the number of basal porechambers was four (hence var. quadricella) compared to three in E. longirostris; it remains to be determined whether var. quadricella should be raised to species rank. Like E. cryptodontia n. sp., Exochella conjuncta (Brown, 1952) has a single pseudospiramen; this has been illustrated by SEM (Gordon 1989). The latter species differs most obviously from E. cryptodontia in having a proportionally smaller, less spout-like proximal peristome and a non-denticulate inner rim.Published as part of Min, Bum Sik, Seo, Ji Eun, Grischenko, Andrei V. & Gordon, Dennis P., 2017, Intertidal Bryozoa from Korea — new additions to the fauna and a new genus of Bitectiporidae (Cheilostomata) from Baengnyeong Island, Yellow Sea, pp. 451-470 in Zootaxa 4226 (4) on pages 462-464, DOI: 10.11646/zootaxa.4226.4.1, http://zenodo.org/record/26506
