Zygometra elegtms. 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. 



[Zygometra comata. (a) Equally mixed spots of dark brown and canary 

 yellow all over the body. 



(J) Orange, the arms covered with darker spots which give them a bronzy 

 appearance.] 



Zygometra punctata. (a) Dull red. 



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

 or less white. 



Zygometra pristina. Deep violet, the cirri white. 



Catoptometra magnified. "Apparently bright yellow, with regular bands of 

 bright red on the arms, like C. ru7)rofl>ava." 



Catoptometra rubroflava. Brilliant yellow, the arms broadly banded with 

 bright red ; the cirri are dull orange red. 



Catoptometra hartlaubi. (a) Yellowish brown, the skeleton whitish. 



(6) Young; bright yellow. 



Catoptometra 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 HIMEEOMETRID^. 



Himerometra magnipinna. (a) Uniform deep violet. 



[(>) 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.] 



Ueterometra nematodon. Dorsally light Hesh color; pinnules ventrally more 

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

 they appear ringed.
