Summary: | Turbinoliidae sp. (Figs. 4 I–J, tables 1−3) Material examined. Galicia Bank: Stn. R 2, 614 m, six very small dead, broken and rolled specimens, mostly fragmentary. Description. Specimens solitary, unattached, much worn, with wall almost even as a consequence of erosion. Largest specimen examined cylindrical (H= 0.6 cm). Base pointed. Calices circular, up to 0.18 cm in GCD and three cycles of septa, with almost all S1 and S2 merging with columella. S1 and S2 subequal and larger than S3, which are rudimentary. Septal faces with small granules. Columella reduced, formed by a single lamella. Corallum light brown. Remarks. The sample suggests Sphenotrochus andrewianus Milne Edwards & Haime (Turbinoliidae Milne Edwards & Haime, 1848). However, in this species the calice and the corallum are laterally compressed and the wall has well-marked costae, whereas the samples at study are cylindrical and smooth. Young corallites of S. andrewianus use to be cylindrical for GCD<0.2 cm (Manuel 1981), but specimens ... : Published as part of Altuna, Álvaro, 2013, Scleractinia (Cnidaria: Anthozoa) from ECOMARG 2003, 2008 and 2009 expeditions to bathyal waters off north and northwest Spain (northeast Atlantic), pp. 101-128 in Zootaxa 3641 (2) on page 116, DOI: 10.11646/zootaxa.3641.2.1, http://zenodo.org/record/217798 ... |
