St. 2H. Two specimens. 
Head about the same length and width as the first segment; 
frontal margin slightly produced in the middle. Eyes wanting-?. 
Mesosome: the first and last segments the shortest, next the 
srd; remaining segments longer, subequal. 
Metasome exclusive of the telson rather wider than the 
mesosome ; not as long as its last two segments; segments well 
defined, 6 in number, including the caudal segment. 
Antenne: the upper not reaching the end of the peduncle of 
the lower ; joints of the peduncle swollen ; flagellum 3-jointed, as 
long as the last joint of the peduncle. Lower antenne not bent 
outwards, peduncle 5-jointed, the last joint the longest; flagellum 
7-joited, rather longer than the last jot of the peduncle. 
Legs: the first 3 pairs subchelate, the 2nd pair the broadest, 
then the Ist,the 3rd much smaller ; the propodos oval, the 1st joint 
longer and wider than the 2nd, about as long as the 5th (propodos), 
the 3rd joint expanded anteriorly to support the base of the 5th, 
the 4th is articulated to the hinder angle of the 3rd and forms 
an elongate triangle of which the inner margin lies along the 
posterior margin of the propcdos. The Ist pair has the propodes 
relatively narrower than the 2nd. The remaining (ambulatory) 
legs are short and of the usual form: all are attached to the 
front of their respective segments, except the 7th which are 
attached to the bind part.
