Specific character. Eyes confluent, placed near the apex of the rostrum. 

 Superior antennse as long as the cephalon. Inferior antennae one-third longer. 

 First pair of gnathopoda longer than the second. 



Length, fa inch. 



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- 

 tennse 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-
