DiagD. Caput segmentis tribus priniis peraei brevius. Segmenta duo priora percei segrnento tertio 

 paullo altiora. Pedes percei quinti paris pedibus quarti paris longiores ; carpus longior quam 

 latior; processus carpalis tuberculo marginis inferioris plus quam duplo longior; tuberculus 

 integer, crenulatus; metacarpus tuberculo magno crenulato instructus. Femur pedum sep- 

 timi paris angustum, feniore pedum sexti paris quarta parte longius. Latera segmentorum 

 plei post producta, acuta. Ramus internus pedum uri secundi paris ramo externo paul- 

 lulo longior. 



The head is shorter than the first three pergonal segments together. The first two pergonal 

 segments are a little deeper than the third. The fifth pair of perceopoda are longer 

 than the fourth; the carpus is longer than broad; the carpal process is more than twice 

 as long as the tubercle on the under margin of the joint; the tubercle is undivided, and 

 crenulated; the metacarjius is provided with a large, crenulated tubercle on the front margin. 

 The femur of the seventh pair is narrow, and is a fourth part longer than that of the sixth. 

 The lateral parts of the phonal segments are produced behind, and sharp-pointed. The 

 inner ramus of the second pair of uropoda is a trifle longer than the outer.
