I am rather doubtful about the correctness of the determination of the specimen from 

 Stat. $7. It has 16 arms about 40 mm. long; there are two IIBr 4(3+4) series, each of 

 them bearing two IIIBr 2 series; the centrodorsal is a ver)- thin pentagonal disk without cirri, 

 though with obsolete cirrus sockets. Though agreeing well with C. minintus, this example does 

 not show the extreme delicacy of build characteristic of that form, and it is possible that it 

 is only a very young specimen of C. novae- guineae. 



A small specimen with 10 arms 20 mm. long was also secured at Stat. 37; the centro- 

 dorsal is much reduced, and bears five cirri which have 8, 9, 10, 12 and 12 segments. 



The individual from Stat. 302 has 19 arms about 90 mm. long; three of the IBr series 

 bear a single IIBr 4 (3 -j- 4) series, each of the latter bearing two IIIBr 2 series. The arms 

 are excessively delicate and attenuated, and greatly elongated, and the pinnules are exceedingly 

 slender and hair-like. The distal ends of the brachials and pinnulars, especially the latter, are 

 exceedingly spinous. The distal pinnules are 9 mm. long. The dorsal interradial perisome is 

 heavily plated, and this plating is continued onto the ventral surface of the disk in the form 

 of deep crescents which extend inward in the interambulacral areas ; the plates of the inner 

 portion of these crescents are thickly studded with long sharp spines. The anal tube is com- 

 pletely plated, the plates bearing numerous long spines. The mouth is central, the anal tube 

 subcentral.

The specimen from Stat. 316 is typical ; there are from 140 to 150 arms; one of the 

 IBr series is 6(5 + 6); the cirri are XVI, 14 — 15. 



The example from Banda is small and very badly broken.
