The eyes are small in comparison with the stoutness of the stalk. 
In the first antenna the third joint is longer than the second. In the 
second antenna the third joint is clasped by the projections of the 
second joint; the slender flagellum is about as long as the stout 
peduncle. 
The palp of the mandible is two-jointed, but it is fairly certain that 
the first joint is composite, having the short first joint coalesced with 
the true second; the true third is strongly fringed with sete. The 
palp of the first maxilla has a broad first joint followed by a narrow 
piece seemingly two-jointed, perhaps a single joint twisted. 
The mouth-organs are very similar to those figured by Ihle for 
C. tumidus.. Here the exopod of the second maxilliped is rather less 
prolonged. ‘The fourth joint of the third maxilliped is of rather 
irregular shape, and its articulation with the third joint forms an 
angle so that the two surfaces resist flattening. 
The fingers of the chelipeds have their confronting margins denti- 
culate each with eight or nine rounded teeth, the extremity of each 
finger being tridentate; a smooth margin on a different level borders 
each row of teeth. The second and third perzeopods have the narrow 
seventh joint terminated by a curved unguis set among rather long 
sete. In the fourth and fifth perzeopods the short stout sixth joint 
carries an unguis-like finger and a spine curving towards it so as to 
form a kind of diminutive chela. The fifth pereeopod is very decidedly 
longer than the fourth. ‘The sternal sulci of the female end widely 
apart and opposite the cox of the second pereopods, 
The first pleopods of the female are slender, single-branched ; the 
four following pairs are two-branched, elongate, the outer branch 
densely setose, the shorter inner one more sparsely. The ova of the 
present specimen were a bright red. They had not passed the oviduct 
into the capacious pleon. ‘The narrow transverse plates attached 
ventrally by the inner corner to the distal part of the sixth pleon 
segment may be regarded as the sixth pleopods or the uropods, though 
their function has become problematical. 
The carapace measures 21 mm. in breadth by 20 mm. in length, 
thus being of considerable size for this genus. A red glow remains 
on various parts of the specimen as preserved. It held about it a 
broad strip of some composite zoophyte.
