The head. is large, aud only a little sborter than the first five perajonal segments together. 

 All the perceonal segments are free. The first pair of pierceopoda are shorter than the 

 second pair. The third and fourth pairs are more than twice as long as the second pair. 

 The last three pairs are somewhat longer than the two preceding pairs; the dactylus 

 is half as long as tlie metacarpus; the carpus of the fifth pair is not longer than the tibia. 

 The lateral parts of the pleonal segments are rounded behind. The peduncle of the last 

 pair of nropoda is more than twice as long as broad. The telson is shorter than the last 

 ural segment, and much shorter than half the peduncle of the last pair of uropoda.
