Diagn. Caput segmentis tribus primis perasi brevius. Segmenta duo priora perai segrnento tertio 

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

 latior; processus carpalis tuberculo raarginis 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 p}edum uri secundi paris ramo externo paul- 

 lulo longior. 



The liead is shorter than the first three perteonal segments together. The first tvfo perwonal 

 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 metacarpus 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 pleonal segments are produced behind, and sharp-pointed. The 

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