First pair of gnathopoda longer than the second.

The head is large and deep, being as long as the first 
four segments of the body, and reaching nearly as deep 
as the lower margins of the coxae. The eyes are con- 
fluent, and appear as a single organ, situated at the 
anterior extremity of the head, where it is produced 
into a hood-like rostrum. The superior antennae are 
scarcely longer than the head, and the flagellum is 
scarcely shorter than the peduncle. The inferior an- 
tennae are half as long again as the superior, and the 
peduncle is about the same length as the flagellum. 
The first pair of legs are simply subchelate, and not 
largely developed ; the wrist is quite as large as the 
hand, and has the infero-anterior angle produced an- 
teriorly ; the hand is ovate, has the palm oblique, but 
not distinctly defined, and is armed with strong hairs. 
The second pair of legs are more slender than the first ; 
the wrist is quite as long as the hand, and has the infero- 
anterior margin slightly produced ; the hand is long-
