| Summary: | Bruunellia sp. (Fig. 4C) MATERIAL EXAMINED. — Porcupine Abyssal Plain, BEN- GAL 5, Discovery 231, stn 13368#47, 48°51.63’N, 16°25.18’W, 4844 m, 16.III.1998, 1 ♀. DESCRIPTION Colour of proboscis and trunk is cream in preserved specimen. Trunk is oval (Fig. 4C), 1 mm long and 0.4 mm at broadest part. Proboscis almost as long as trunk, round in transverse section and without ventral groove (Fig. 4C). Mouth located at base of proboscis. Integument is smooth, thin and transparent, coils of gut visible. Ventral setae absent. Internally, there is a single, tubular gonoduct on right side of nerve cord with basally located gonostome. Gut contents moulded into oval faecal pellets. Cloacal bulb is present. Anal vesicles not seen, probably damaged. REMARKS The present specimen is extremely small with a trunk length of only 1 mm and it seems very likely that it is a juvenile. This specimen has been assigned to the genus Bruunellia on account of the structure of the proboscis which is round in cross-section. ... : Published as part of Biseswar, Ramlall, 2006, Additions to the deep-sea echiuran (Echiura) fauna of the North-East Atlantic, pp. 853-864 in Zoosystema 28 (4) on pages 863-864, DOI: 10.5281/zenodo.4689879 ... |
