this gradually becomes reduced to a .rounded ventral projection of 
the ventro-lateral angle, in the terminal portion disappearing alto- 
gether; distal pinnules slender, 14 mm. or 15 mm. long, with 
twenty-five joints, which have the distal ends produced and finely 
spinous as in the preceding pinnules; the production of the ventro- 
lateral edge of the pinnule joints is not found. much further out 
than the middle of the arm. 
Colour (in spirits).. — Pinkish white; or deep violet, the 
Sadie of the dorsal pole of the centro-dorsal with a spot, 
the I Br series and proximal half of the arms with a lateral line, 
of darker. 
Singapore; April 20, 1906. The type. 
June 17,.1904. Cotype. 
Remarks. — This species appears to be quite distinct from 
C. perspinosa; it has fewer cirrus joints, all of which are short, 
none being :so long as broad; the cirri are comparatively . short, 
and stout basally, tapering distally; P,, P,, and P, are enlarged 
and spine-like, nearly equal, but P, is much shorter and less stiff; 
the middle and distal pinnules are shorter than in perspinosa with 
the distal ends of. the joints' but” slightly expanded and bearing 
only minute spines. It differs from the more slender C. suavis in 
having the proximal pinnules proportionately much longer and 
Iore enlarged, the distal pinnules longer and stiffer, and the distal 
Cirrus joints with double instead of single dorsal spines. From the 
smaller and more slender CO. discolor it differs in the proportions of 
its lower pinnules, P, in that species being very small and weak 
while P, is longer and stouter than P, and exceeds the distal 
Pinnules. in length. 
Dr. Hartlaub's specimen from Amboina which he referred 
to perspinosa I take to be in reality this species. It had cirri 
XVI, 35—48, about 23 mm. long; the pinnules appear to be the 
Same, The only difference which is apparent on comparing the 
Specimens from Singapore with his figure is that in the latter the 
Cirrus joints are shown to be slightly longer.
