and longer than the peduncle. The peduncle of the third pair is nearly three tiines as 

 long as broad, and scavcely longer than the inner ranius; the rami are equal in length, 

 and are elongate and sharp-pointed as in the two preceding pairs. 



The telson is almost twice as broad as the peduncle of tlie last pair of uropoda, 

 and fully as long as two thirds of the same peduncle.

The head is long and deep, and much longer than the first four perasonal segments together. 

 The first two peneonal segments are coalesced, the following are free. The carpus of the 

 first pair of perceopoda is dilated and produced, forming a process, which is half as long 

 as the hind margin of the metacarpus. The carj)us of the second pair is produced; the 

 front side of the carpal process is somewhat more than half as long as the hind margin 

 of the metacarpus. The metacarpus of the first and second pairs has two bristles on the 

 front margin; the hind margin is serrated, with simple teeth; the dactylus is long. The 

 third and fourth pairs are longer than the two preceding; the carpiis and metacarpus are 

 serrated; the dactylus is long. The last three pairs are a little longer than the two pre- 

 ceding; the femur is broad; the carpus is longer than the tibia; the carpus and meta- 

 carpus are serrated. The lateral j)arts of the pleonal segments are obtusely rounded be- 

 hind. The peduncle of the last pair of uropoda is more than twice as long as broad. 

 The telson is a little longer than broad, and is shorter than the last ural segment; it is 

 about as broad, but not half as long, as the peduncle of the last pair of uropoda.
