Rostrum as large as, or larger than, supra-orbital spines ; clasping pro- 

 cesses from the epimeral plates small, attached only to the under-surface 

 of the rostrum. 



, Carapace armed with forwardly directed sharp spines only, which are 

 not separated by rows of hairs ; there are no ffettened tubercles on the 

 carapace. 



Abdomen not sculptured, but provided with scattered small blunt spines, 

 without hairs ; abdominal pleura as in J. lalandii, except that the large 

 spine is not so markedly curved backward. 



Antennules longer than the peduncle of the antenna ; antennae shorter 

 than the body. 



First pair of peraeopods with 3 small spines on the under-surface of 

 the ischium, and with a large spine on the under-surface of the merus ; 

 last four pairs with 1 spine on the distal end of the upper surface of the 

 merus. 



Colour : Upper surface dark olive-brown ; sides of carapace and ab- 

 dominal pluera chestnut, with a few small scattered cream spots ; antennae 

 and legs reddish-brown.
