The orioinal specimen u|)on which this species is based is small and probably immature. 
The long- 1\ and the rather unusually spinous condition of the distal ends of the pinnule 
segments suggest a com])arison with the small species of Compsomdra\ but the relatively large 
P, shows that it cannot be referred to the genus. The specimen recorded in 191 i (Cat. 
N" 36024 U. S. Xalional Museum) appears to be a more developed individual of the same 
species; the arms are about 50 mm. long, and the cirri are i i mm. long; P, is 5 mm. long, 
with 12 segments; P., is also 5 mm. long, with 11 segments, similar to Pj; P., is 4 mm. long 
with 9 segments, proportionately shorter and more slender; P, is similar, with 8 segments, 
nearly or quite as long; P. is 4 mm. long with 10 segments.

a' Cirri very long and slender, from the third to one half of the arm length, 
composed of 25 — 33 (usually 25 — 26) much elongated segments of which 
the longest are about five times as long as the pro.ximal diameter, and the 
last three or four are about two and one half or three times as long as 
broad; no opposing spine; terminal claw very slightly curved (1' hi lip pine 
Islands; 141 — 144 Metres) chamberlaini 
a- Cirri shorter and less slender, about one quarter of the arm length, composed 
of 16 — 18 segments which are not especially long, the longest pro.ximal 
(fifth-seventh) being nearly or quite three times as long as broad pro.ximally, 
and the last three or four less than twice as long as the distal breadth; a 
prominent opposing spine; terminal claw strongly curved (Lesser Sun da
