Material examined. Stn. 10: 19.11.2009, 17 m—several fertile colonies, to 4.5 cm high, on worm tubes and bivalve shell; 0 2.12.2009, 15– 20 m— several fertile colonies, to 3 cm high, on various substrates such as sponge, stem of unidentified hydroid, bryozoan, dead gorgonian, and stylasterid (MHNG-INVE- 68717). Stn. 11: 30.11.2009, 15– 18 m—fertile colonies, to 2 cm high, on dead tips of gorgonians and bivalve shells attached to them (part as MNHN-IK. 2009 - 827). Description. Colonies to 4.5 cm high, arising from root-like hydrorhiza; flaccid, do not stand up when out of water. Perisarc quite thick and horn-coloured in older parts, becoming thinner and transparent towards extremities. Stems branching irregularly to roughly alternate, mainly in one plane; with up to 4 th order branches. Both stems and branches polysiphonic, grading to monosiphonic distally. Internodes in monosiphonic parts long, geniculate, slightly curved, with variable number of basal annuli. Hydrothecae borne terminally on variably annulated branchlets; deep-campanulate (510–705 µm long), thin-walled, with ca. 8–11 large, pointed, triangular cusps slightly inclined to one side (fig. 2 E, G) and slightly projecting inwardly (fig. 2 F, upper figure); diameter at aperture 220–305 µm; diaphragm transverse, 95–125 µm wide. Gonothecae arising from axils of branchlets; smooth-walled, long (730–920 µm), inverted-conical, tapering over most of length, maximum width 225–250 µm; constricted abruptly below rim, diameter at aperture 200– 220 µm; pedicel short and smooth; generally 3 medusa buds on blastostyle. Remarks. Leloup (1935), followed Broch (1909) who recognized only two valid campanulariid genera, viz. Campanularia Lamarck, 1816 and Laomedea Lamouroux, 1812, distinguishable by the structure of their hydrothecal diaphragms. He therefore considered that both Obelia fragilis Calkins, 1899 and Clytia fragilis Congdon, 1907 should be included in the Lamouroux’s genus, the latter species thus becoming a junior synonym of the former. The replacement name L. tottoni was then introduced for Congdon’s species. However, the description and figure of Congdon’s material may apply to various species of Clytia Lamouroux, 1812, and nothing indicates precisely that he actually had C. tottoni in his hands. His specimens were most probably monosiphonic despite their size (i.e. 12–18 mm high), a situation not met with in C. tottoni, which, according to the present material, forms polysiphonic stems in colonies higher than ca. 8 mm. Clytia fragilis was assigned to the synonymy of C. linearis (Thornely, 1900) by Calder (1991), but reinspection of the type material is necessary for a reliable identification. I therefore avoid including Congdon’s species in the synonymy and geographical records of C. tottoni. The most confident identification of C. tottoni is, of course, that by Leloup (1935). His material clearly possessed polysiphonic colonies, the main distinguishing character of this species. On the other hand, Nutting (1915) and Wedler (1973) obtained only small, monosiphonic colonies, and their respective descriptions do not allow unambiguous identifications of their specimens. These records are here considered as doubtful. Calder (1991) assigned Vervoort’s (1968) material to C. linearis, and I agree. Equally doubtful are considered the Chilean record by Leloup (1974) and the Korean one by Park (1998), mainly on geographic grounds. Both may represent separate species with similar trophosome, but having different medusae. The Caribbean Clytia laxa Fraser, 1937 corresponds in every respect to Leloup’s (1935) species, as well as the eastern Atlantic specimens assigned to Clytia arborescens Pictet, 1893 by Billard (1906) and Medel & Vervoort (2000). They are included here in the synonymy of C. tottoni. Calder (1991) considered C. tottoni as a synonym of C. linearis, an opinion not shared here. Thornely’s (1900) species is always monosiphonic in habit and its hydrothecae are provided with longitudinal “keels” extending downwards from the cusp tips (Lindner & Migotto 2002), a situation not met with in C. tottoni.

Bonaire Island, the Netherlands Antilles. Remarks. This species is easily recognizable due to its generally shallow, wide hydrotheca, with even rim, and subhydrothecal spherule (Cornelius 1982). I have little to add to the previous descriptions of its trophosome (Leloup 1935, Millard 1975, Cornelius 1982, Calder 1991 d, Migotto 1996). The size of hydrothecae is highly variable among specimens from one colony (see table 2). The tentacle number in the present specimens varies between 24 and 30. There are 6–14 basal annuli and 4–7 additional ones in the middle part of the hydrothecal pedicels. The diaphragm of hydrotheca is obviously inclined to one side. Fertile material of C. hummelincki has rarely been described (Millard 1966, 1975). In the present specimens, the gonotheca is borne on a short, twisted pedicel (1–2 twists) arising from the hydrorhiza; it is inverted-conical in shape, widening gradually from base towards aperture. In lateral view, it appears asymmetrical, with one side straight to slightly curved, and the opposite one with significant basal curvature; both walls are smooth throughout. The distal end of the gonotheca is truncated; the aperture is wide and circular, closed by a thin, convex layer of perisarc. One or two medusa buds are present in the four gonothecae examined, but no morphological details could be observed. Additional studies are necessary in order to describe the complete life cycle of this species. Distribution. Reported infrequently from warm waters of the western and eastern Atlantic, and eastern Pacific (Calder et al. 2003). TABLE 3.

Description. Colonies erect with rhizocaulomic hydrorhiza, becoming simple distally. Hydrothecae, nematothecae and the singly occurring gonotheca arising perpendicularly to the hydrorhiza. Hydrothecae borne on short, smooth pedicels; deeply campanulate, tapering basally, and there provided with a transverse, thing diaphragm; walls parallel, widening distally; rim well-marked, aperture closed by a conical operculum composed of 13–15 elongate, triangular flaps, not connected between them, and folded either inwards or outwards. Nematothecae given off irregularly among the hydrothecae; globular, borne on moderately-long pedicels, aperture distal, circular. Gonotheca short-pedicellate, fan-shaped, strongly flattened “dorso-ventrally”, aperture distal, large, spanning from one side to the other (Fig. 2e, 3); margin irregularly serrated, possibly resulting from rupture of the perisarc at maturity; distal part of the walls with numerous longitudinal ridges (Fig. 3). Biology. Egmundella grimaldii has been found growing on a campanulariid hydroid (Leloup 1940). In our material, one colony was found growing on Sertularella gayi (Lamouroux, 1821), one on a bivalve shell, and one on an ophiuran. A fertile colony was found in December. Distribution. This species was previously found only once, by Leloup (1940), in the Bay of Biscay, between 748 and 1262 m. Our material was found off both Morocco and Western Sahara at depths from 30 to 722 m. Remarks. This is the first time this species has been found since its original description (Leloup 1940), and our report also represents the first account of its gonotheca. The measurements of our material (see table 1) agree with those provided by Leloup (1940). The large size of the hydrothecae and their short pedicels are specific characters, allowing us to distinguish it from C. producta. Egmundella grimaldii resembles in the shape of colonies to those of E.fasciculata Fraser,1942,from Massachusetts, USA. Nevertheless, there are several morphological characters which allow their specific differentiation. The latter is distally ramified, its nematothecae are borne on both the hydrorhiza and hydrothecal pedicels, and the hydrothecal aperture is closed by an operculum composed of 8–10 flaps. None of these features were observed in our material; moreover, the opercula of our hydrothecae are composed of a higher number of flaps. Schuchert (2016) noted that the hydroid of E. grimaldii is similar to that of Cyclocanna producta (G.O. Sars, 1874) [as E. producta in his paper], and stressed the need for the study of new material to evaluate whether it is a mere variant of C. producta (see below). Our material shows the same diagnostic characters as those of the holotype, and the presence of a fertile specimen supports its specific validity. Despite the gonothecae of both species being quite similar in shape and size, they nevertheless differ in the presence of transversal and basal undulations in C. producta (Schuchert 2016: 222), versus longitudinal and distal ridges in the present species. In addition, comparison of the present material with colonies of C. producta, collected from the same study area, convinced us that they are distinct species (see below). The morphological similarities between the gonothecae of E. grimaldii and C. producta suggest that both species could be congeneric. Nevertheless, and like Schuchert (2016), we considered necessary to study additional fertile material, including molecular studies in order to clarify its taxonomic position.Published as part of Gil, Marta & Ramil, Fran, 2023, The genera Egmundella Stechow, 1921 and Cyclocanna Bigelow, 1918 (Cnidaria, Hydrozoa) in waters of Northwest Africa, pp. 490-504 in Zootaxa 5264 (4) on pages 492-495, DOI: 10.11646/zootaxa.5264.4.2, http://zenodo.org/record/783696
