This species is smaller in size than any other of the genus except 
QO. australiensis and QO. frigida. Wt differs from either of these in the 
character of the spicules and in the rugosity of the polyps. 
Type.—Cat. No. 22594, U.S.N.M., Albatross station 4065, between 
Hawaii and Maui islands, 491-500 fathoms. 
Family ALCYONIDA‘ Verrill (emended). 
Colonial forms with the proximal portion of the stem usually 
devoid of polyps. Ccoenenchyma thick. Spicules abundant. Polyps 
retractile. 
Genus ANTHOMASTUS Verrill. 
Colony forming a rounded mass supported on a short peduncle. 
Polyps retractile. Siphonozoids numerous. Ccenenchyma fleshy.

collected by H. M. S. Challenger during the years 1873-1876, 1889, p. 
243. : 
A colony of this species was taken from a depth of 122-143 fathoms 
off the north coast of the island of Maui, Station 4101. The speci- 
men agrees well with the description of the original which was 
secured off the coast of Japan from a depth of 565 fathoms. 
Family NEPHTHYID Verrill. 
Branched colonial forms, much like the Alcyonide except that the 
tentacles do not retract within the body cavity of their polyps, but 
simply fold over the oral disk in retraction. 
Genus SPONGODES Verrill. 
Walls between the canals of the stem with few or no spicules. 
Polyp-heads with large conspicuous fusiform spicules, bundles of 
which overarch the heads themselves. Cortex with large and abun- 
dant spicules. 
SPONGODES ALEXANDERI, new species. 
Plate XLI, fig. 3; plate XLVII, fig. 2. 
Colony attaining a height of about 64 mm. Stem without polyps 
for about 25 mm. above the constricted base. A large branch (broken) 
arises about 30 mm. above the base, and near the top the colony is 
broken up into five rather slender, finger-like branches. The polyps 
are single, and scattered over the upper part of the stem and branches, 
but tend to form small terminal clusters of closely aggregated. but 
fairly distinct polyps,
