tooth at their external angle. The eyes are set on short 

 thick peduncles. 



The basal joint of the external antenna; is elongated, 

 and enters well within the long and narrow hiatus existing 

 between the front and the orbits, but does not reach the 

 inner and inferior angle of the orbit, and the very small 

 flagellum is contained within this hiatus. The fourth joint 

 of the external maxillipedes is very obliquely truncated at 

 the distal extremity, and not (or slightly) emarginated at 

 the antero-internal angle. The first pair of legs in the 

 adult male is large and massive, unequal ; the palms 

 without ridges or tubercles ; the fingers of the larger one 

 are armed with one or two large rounded tubercles on its 

 inner edge. The walking legs are moderately long and 

 smooth ; subcylindrical or slightly compressed. 



The abdomen is six-jointed in the male and seven- 

 jointed in the female.

The carapace is smooth, and has no hairs anywhere ; 

 it is a little broader than long. The front, in breadth, 

 does not exceed the length of the space between the 

 sternal plastron and the anterior edge of the antennulary 

 fossae ; it is divided into three lobes by deep notches, the 

 middle one being largest and having an indistinct division 

 in its centre ; there is a small tubercle at the outer angle
