The specimen from Stat. 99 is typical, and resembles others at hand from Australia; 
it is yellow brown, the cirri and pinnules purple. 
A typical example from Stat. 273 has the arms i 15 mm. long, and the cirri XV, 32 — 34, 
22 mm. long; the longest cirrus segments are slightly broader than long; the disk is almost 
completely covered with plates. There are twelve similar specimens, and two small and immature. 
A four-rayed individual similar to that described was secured; the missing ray appears 
to be the anterior. 
These specimens exactly resemble others at hand from Queensland and from north- 
western Australia. The cirri are comparatively slender, tapering distally. 
Remarks. — Dijardix and Hlpe mention that in the Paris Museum they found a 
comatulid bearing the name Comatnla dibrachiata. I examined what I suppose is the same 
specimen, a dried individual brought from Australia by MM. Peron and Lesueur. In my notes
