Scottoecia—a new genus of halocyprid ostracod, with the description of Scottoecia arabica nov. sp. and the redescription of Bathyconchoecia darcythompsoni (Scott, 1909)
No full textOn re-describing two species originally attributed to the halocyprid genus Bathyconchoecia (B. darcythompsoni Scott, 1909 from the North Atlantic and B. lacunosa sensu James 1973 from the Gulf of Oman) they were found to show substantive differences from the type species for the genus, B. paulula. These differences are: 1. Several carapace characteristics including size, the structure of the rostra and incisure, and the locations of the openings of the carapace glands.2. Limb structures notably of the mandibles.3. The exceptionally long dorsal terminal seta on the male sixth limb.4. The structure of the copulatory appendage. These two species are placed in a newly defined genus Scottoecia, for which S. arabica is designated as the type species. The original descriptions of three other Bathyconchoecia species, show that they belong to Scottoecia, namely S. crosnieri (Poulsen, 1969a), S. subrufa (Angel, 1970a) and S. foveolata (Deevey, 1968). This has been confirmed for the first two species by the examination of the type material. Another species Bathyconchoecia baskiae Poulsen, (1969b) has similar mandibles, and is probably closely related, but does not share all the characteristics of the new genus.The validity of the previous classification in which Bathyconchoecia is included in the subfamily, the Euconchoecinae, is questioned
Septemoecia Angel & Brandåo 2018

Towards a full inventory of planktonic Ostracoda (Crustacea) for the subtropical Northwestern Atlantic Ocean
No full text92 species of planktonic ostracods were identified from five total water column samples of macroplankton collected from the surface to depths of 5000 m in the northwest subtropical Atlantic. Thirteen of these species are either totally novel or previously undescribed. This brings the total inventory of planktonic ostracods known from this region to118 species, and for the whole Atlantic to 153. All but one of the undescribed species were collected from depths >1000 m. This region is already the most comprehensively studied in the global ocean for plankonic ostracods. Similar studies conducted in other less well studied regions particularly in the Pacific and Indian Oceans will reveal far higher numbers of novel species
The modernist angel: Art at the Limits of the Human in D. H. Lawrence, H. D. and Mina Loy
No full textPhDThe subject of this thesis is a figure that might provisionally be called the *modemist
angel'. Focusing on modernist literature, and more particularly on the work of D. H.
Lawrence, H. D. and Mina Loy, it aims to isolate from the many angels found in all periods
and all types of art a historically specific and intellectually coherent paradigm: an angel of
and for its modernist times. A figure of precisely this type could be said to exist in the
form of Walter Benjamin's 'angel of history'. Critics who address the question of the
modern angel in texts by Franz Kafka and Rainer Maria Rilke often do so in conjunction
with the problem posed by the angel of history. Beginning with a chapter on Benjamin,
this thesis nevertheless follows a different trajectory. Over five chapters, it explores a
modernist landscape formed not only by Lawrence, H. D. and Loy, but also by European
and American writers such as A. R. Orage, Allen Upward, Ezra Pound, Wallace Stevens,
Havelock Ellis, Edward Carpenter, Sigmund Freud and Friedrich Nietzsche. Although the
angel that emerges from this investigation might, in some respects, be said to anticipate
Benjamin's later version, this figure is also very different, standing for a project that is
distinctively, and recognisably, modernist in nature. He/she (the sex of the modernist
angel is often open to question) represents an attempt to reconcile the divine
responsibilities of the artist with the material and gendered conditions of being,
specifically of being human, in the modem world. This thesis looks again at the clash of
intellectual paradigms in the early-twentieth century - notably, the confrontation of the
Romantic view of art as a superhuman or sacred undertaking with the psychoanalytical or
evolutionary idea that all human endeavour is underpinned by sub-human motives - and
suggests the angel as a new and instructive figure through which to think the perilous
limits between the human and the divine in modernist literature

Planktonic ostracods (Myodocopa: Halocyprididae) from abyssopelagic depths in the Atlantic, North Pacific and Gulf of Oman: Chavturia abyssopelagica (n. gen., n. sp.), Halocypretta profunda (n. sp.), Halocypretta parvirostrata Chavtur and Stovbun, 2008 and Halocypretta striata (Müller, 1906)
No full textA novel species and genus of halocyprid ostracod, Chavturia abyssopelagica, and a new species of Halocypretta are described from depths >3000 m in the Atlantic. The new genus is related to Halocypretta, itself a genus that has only recently been described from deep waters in the North Pacific. Supplementary observations are made on the type species, Halocypretta parvirostrata, based on additional specimens from the North Pacific. Halocypretta striata from the Gulf of Oman is reported for the first time since it was first described and is redescribed in detail. All four species are illustrated and compared using a set of meristic characters

Chavturia Angel, 2013, new genus
No full text<i>Genus Chavturia</i>, new genus <p> <b>Type species.</b> <i>Chavturia abyssopelagica,</i> new species.</p> <p> <b>Composition.</b> At present the genus is monospecific.</p> <p> <b>Etymology.</b> The genus is named in the honour of Dr Vladimir Chavtur, who has contributed extensively to the systematic, taxonomy and ecology of myodocopid ostracods from the Pacific, Arctic and Southern Oceans.</p> <p> <b>Generic Characteristics.</b> Large deep-living halocyprid ostracods. Lateral aspect of carapace ovoid, lateral aspect slim (~40 % carapace length). Left asymmetrical carapace glands open close to posterior dorsal corner just anterior to the posterior end of the hinge. Right asymmetrical glands close but slightly above posterior ventral corner. Rostrum small. Large flange on lower margin of incisure. Frontal organ with a two-segmented stem that is as long as the limb of the first antenna and an S-shaped capitulum of similar length. The first antenna appears to be five-segmented. The second segment has a short terminal seta that curves anteriorly. The penultimate segment carries two sensory setae that are subequal with two of the three setae on the terminal segment, and are about half the length of the longest terminal seta. The protopodite of the second antenna is about a third the carapace length and the first exopodite segment is of similar length. The endopodites have no processus mamillaris and all the setae are long. The mandible is similar to the general halocyrid pattern, but the maxilla has an unusually long basal segment. The fifth and sixth limbs show little sexual dimorphism.</p>Published as part of <i>Angel, Martin V., 2013, Planktonic ostracods (Myodocopa: Halocyprididae) from abyssopelagic depths in the Atlantic, North Pacific and Gulf of Oman: Chavturia abyssopelagica (n. gen., n. sp.), Halocypretta profunda (n. sp.), Halocypretta parvirostrata Chavtur and Stovbun, 2008 and Halocypretta striata (Müller, 1906), pp. 401-431 in Zootaxa 3709 (5)</i> on pages 402-403, DOI: 10.11646/zootaxa.3709.5.1, <a href="http://zenodo.org/record/222440">http://zenodo.org/record/222440</a>
