Zygonietra elegans. — -The color in life is recorded as very variable, with no 

 details. The black and white comatulids mentioned by von Willemoes-Suhm were 

 probably this and the preceding species. 



[^Zygonietra comata. — {a) Equally mixed spots of dark brown and canary 

 yellow all over the body. 



{h) Orange, the arms covered with darker spots which give them a bronzy 

 appearance.] 



Zygometra punctata. — {a) Dull red. 



(&) Purple of a rather pale shade; pinnules yellowish at the tips; cirri more 

 or less white. 



Zygometra pristina. — Deep violet, the cirri white. 



C atoptoinetra magnlfica. — "Apparently bright yellow, with regular bands of 

 bright red on the arms, like C. ruhrofavay 



C atoptoinetra ruhro-flava. — Brilliant yellow, the arms broadly banded with 

 bright red; the cirri are dull orange red. 



C atoptoinetra hartlauhi. — (a) Yellowish brown, the skeleton whitish. 



(&) Young; bright yellow. 



C atoptoinetra ophiura. — [a) Dull olive green, the disk ambulacra and the 

 perisome of the pinnules dark brown. 



{b) Bright yellow, the arms broadly banded with bright red. 



Family HIMEROMETRID^. 



Himerometra viagnipinna. — {a) Uniform deep violet. 



[(6) Arms transversely barred with brown, at the base whitish or light straw 

 yellow; pinnules barred with whitish and brown; anal tube straw color, spotted 

 with light brown. 



(c) Division series dull ochre; the arms crimson, shading to rich chocolate 

 at the tips. 



{d) Arms dorsally wine red, becoming darker on the division series, regenerat- 

 ing arms tending to crimson, ventrally light pinkish gray with transverse lines; 

 pinnules dorsally like the arms ventrally; enlarged proximal pinnules, disk, 

 ambulacral groove of the arms, and the ventral surface of the pinnules dark wine 

 red, tending toward crimson on regenerating arms; cirri ventrally colored like the 

 division series, dorsally slightly lighter, and with silver tips. 



(e) Dark wine red, the dorsal surface of the arms washed with silver; centro- 

 dorsal pink; cirri slightly lighter dorsally than ventrally, with white tips. 



(/) Dark wine red with two rows of alternating white spots along the ventral 

 surface of the arms. 



{g) Medium dark wine red, the centrodorsal pink, the cirri dorsally slightly 

 lighter with the tips white.] 



Heterometra nematodon. — Dorsally light flesh color; pinnules ventrally more 

 or less violet; cirri dark violet, many of the segments dark in the middle, so that 

 they appear ringed.
