bar-like ones placed haphazard, as it were, on the tentacle bases; 
giving an exceedingly unkempt appearance. Small bar-like spicules 
are placed transversely on the distal parts of the tentacles. ; 
Color.—Polyps straw VION stem ivory white, horny internodes 
very dark brown. 
Lype.—Cat. No. 22559, U.S.N.M., Albatross Station 4174, off Bird 
Island, 735-865 fathoms. 
Genus LEPIDISIS Verrill. 
Axis with long tubular calcareous joints, alternating with short 
horny ones from which the branches arise. An external layer of small 
seale-like spicules 1s found covering the large fusiform spicules. 
LEPIDISIS LONGIFLORA Verrill.: 
Lepidisis longiflora VERRILL, Bull. Mus. Comp. Zool., XI, No. 1, 1883, p. 19. 
A specimen taken by the Albatross, northwest coast of Oahu, at 
Station 4121, 316-251 fathoms (Cat. No. 25358, U.S.N.M.), agrees 
with the original description of this species. 
The type and other specimens studied by Verrill were taken from 
four stations in the West Indies, at depths of from 461 to 805 fathoms. 
Genus ACANELLA Gray (emended by Verrill). 
Branches arising from the short horny internodes of the axis cylin- 
der, spicules numerous in tentacles. No external layer of scale—hke 
spicules. 
ACANELLA EBURNEA (Pourtalés). 
Mopsea eburnea PouRTALES, Bull. Mus. Comp. Zool., I, 1868, p. 182. 
A specimen which I refer with doubt to this species was secured at 
Station 4121, northwest coast of Oahu, 216-251 fathoms. It is much 
broken, but was probably about 18 inches high. Branching very 
irregular, with a tendency to the formation of whorls. The polyp 
spicules were smaller than described by Verrill, but otherwise much 
the same. 
The specimens studied by Pourtalés and Verrill were taken from 
five stations in the West Indies, at depths of from 288 to 955 fathoms. 
Family PRIMNOID # Valenciennes (emended by Verrill). 
Colonial forms with calcareous roots. Axis cylinder calcareous or 
horny, but never with alternating calcareous and horny joints. 
Calyces prominent, almost always with an operculum composed of 
eight scale-lke spicules, and movable. Polyps often in whorls. 
Spicules usually scale-hke.
