The body is minutely granulate and pubescent. 

 The eyes are large. 



The rostral process of the head is rather acute, and has 

 a slight median elevation. 



The epistome has an arcuate crest, and a triangular area 

 on a different plane occupies the space between it and the 

 rostrum. The lateral limbs of the epistome thin away and 

 recede ; below the crest the surface is rather excavated. 



The epimeral plates of the thoracic segments, except the 

 first, are marked by suture lines, and project a little laterally 

 before taking a vertical direction, then the ends are a little 

 turned outward again, the second, third, fourth, and fifth 

 with points a little produced backwards also. 



The process of the seventh thoracic segment is some- 

 times nearly truncate, in other specimens abruptly narrowed 

 to a small obtuse point. In some males there is a small 

 tubercle on the posterior edge on each side of this process. 



The after - portion of the abdomen has a very shallow 

 longitudinal median depression, and it is more granulate 

 than other parts of the body. The terminal process is dor- 

 sally raised and keel-like, with a hump. The under side of 

 this process has also a narrow longitudinal keel, and imme- 

 diately in front of it is a slight excavation, apart from the 

 general excavation of the abdomen. 



A small group of five or six long setae springs from the 

 outer side of the mandible close by the molar process. 



The legs are very furry on the usual joints. 



The upper surface of the external ramus of the uropod 

 is excavated for nearly the whole of its length, having a 

 raised and thickened external border : it is produced much 

 beyond the end of the abdomen. The venation of the 

 uropods is seen in the females and young males, but 

 is obscured in adult males. The inner margin of the inner 

 ramus is slightly bent, to conform to the indentation at the 

 side of the terminal process of the abdomen. 



The adult female is quite without process to the seventh 

 segment of the thorax, and there are two faint median 

 tubercles on the posterior portion of the abdomen.
