“Description. The corallum is ceratoid, expanding into a large, elliptical calice. The pedicel diameter, which measures one-fourth to one-half the calicular diameter, is reinforced by concentric layers of stereome. The pedicel re-expands basally into a large, thin, en crusting sheet, by which the corallum is attached. The largest specimen examined measures 45.0 X 65.0 mm in calicular diameter, but 18 X 14 mm is more typical. The theca and septa are initially very thin and fragile until they are secondarily thickened with stereome. The theca is very smooth and often porcelaneous, with scalloped growth lines, the peaks of which correspond to the S1-3. Costae rarely occur, but when expressed they are faint to well developed ridges in the upper one-third of the corallum, corresponding to S1-3.


Septa are usually arranged in six systems and four cycles but often four of the S3 are enlarged, giving the appearance of eight regular systems with four cycles (64 septa). Si and S2 are equal in size and highly exsert. S3 are less exsert and much smaller; S4 are not exsert and become rudimentary in the lower fossa. The inner edges of all septa are entire and usually straight, but sometimes those of the S3 and S4 are slightly sinuous; more rarely those of the S1 and S2 are also sinuous. Septal granules vary from low and rounded to narrow and pointed, and are arranged in lines parallel to the trabeculae, either on the crests of small septal undulations or over a flat septal face.


The fossa is elongate, deep, narrow, and bordered by the inner edges of the S1 and S2. A solid, rudimentary columella forms deep within the fossa by the fusion of the lower, inner edges of the S1 and S2.” Cairns 1979, pp. 153-156.



“Discussion. Of the two new specimens reported, the one from Albatross station 2785, about 10 km from the type-locality of D. eburneum Moseley, is identical to the syntypes of that species. The small specimen from Eltanin station 1592, however, has prominent costal ridges and highly exsert septa, similar to those of the holotype of D. nobile Verrill.



Material. Eltanin sta. 1592 CD, USNM 47530; Albatross sta. 2785 (1), USNM 19173. Specimens listed by Cairns (1979), USNM. Syntypes of D. eburneum; holotypes of D. nobile and D. galapagense.” Cairns 1982, pp. 46-48.



“Types. The holotype of D. cailleti is lost; it is not present at the MIZS or the MNHNP. The type of G. eburnea is one of the few Pourtales types that is missing (presumed lost) from the MCZ. Moseley's D. eburneum is based on five syntypes collected from Chall-306. They are deposited at the BM (1880.11.25.65). The holotype of D. nobile Verrill, 1885, is at the USNM (type number 7964). Most of the type. material of D. vitreum Alcock, 1898, is at the Indian Museum, Calcutta, but five syntypes are deposited at the MNHNP and two are at the ZMA (Coel. 1198). The type of D. galapagense Vaughan, 1906 is at the USNM. The type of D. delicatum was not traced. Type-Locality. Lesser Antilles (no specific location or depth was given).” Cairns 1979, pp. 153-156.



“Distribution. Widespread in Northern Hemisphere in all oceans: off Galapagos Islands; off Japan; off India; off Morocco; northwest Mediterranean; Celtic Sea; off Madeira; off Azores; off Nova Scotia; off Georgia, United States, to off Suriname (including Gulf of Mexico and Caribbean). In Southern Hemisphere known from off Uruguay; off Burdwood Bank; off Chile (Map 12). Depth range: 86-2165 m.” Cairns 1982, pp. 46-48.
