The larger specimen has about 60 arms which are about 90 mm. long; the cirri are 
XXI, 10 — II, 8 mm. to 9 mm. long. 
The smaller is in the ten armed juvenile stage, the arms being 25 mm. long.

The cirri are XXII, 13, 13 mm. long; the first segment is short, the second twice as 
long as its median diameter, the third about three times as long as its median diameter, the 
fourth and fifth the longest, from three to three and one half times as long as the median 
diameter; the foUov/ing segments decrease rapidly in length so th.at the antepenultimate is 
sliehtlv loneer than broad and the penultimate about as loner as broad ; the fifth is a transi- 
tion segment; the following have small, but sharp and prominent, dorsal spines Vv^hich are 
acutely triangular in end view ; the opposing spine is subterminal, slender, and very sharp, in 
height equal to about one third the lateral diameter of the penultimate segment ; the terminal 
claw is nearly or quite twice as long as the penultimate segment, very slender and modera- 
tely curved basally, but becoming nearly straight in the outer two thirds. 
The arms are about 60 in number, 100 mm. long. 
The mouth is subcentral and the anal tube submarginal. 
The terminal comb on the proximal pinnules has 11 or 12 teeth. 
Comaster sibogae is most nearly related to C fruiicostis, differing from that species 
chiefly in its proportionately longer and more slender cirri, which have proportionately longer 
segments and sharper and more prominent dorsal spines in the distal portion.

The cirri are XXVII, 15 — 17, 12 mm. to 15 mm. long; the first segment is about 
twice as broad as long, . the second about twice as long as the expanded distal^ ends, strongly 
constricted centrally, the third from three to four times as long as the median diameter, con- 
stricted centrally, though not so much so as the preceding ; the fourth segment is slightly over 
twice as long as the proximal diameter; the following segments rapidly decrease in length so
