there is no such impression; the first se<rnicnt is a little shorter tlian thu second; the se- 

 ventli segment is the longest. 



The /irst pair of pereiopoda (1*1. VIII, lig. 12) havc tlie carpus dilated at the binder 

 lower corne]', and i'uvinded, but not pi'odueed into a process. 'Jlie metacarpus is a little 

 loiiger tlian the earpus, sharply serrated along the hinder margin. The dactylus is longer 

 than half the xnetaearpus, serrated along the hinder, eoneave margin. 



The necond pair (Pl. VIII, lig. 13). The ti b i al process is longer than half the cai'pus, 

 fringed with long bristles. The earpus ecjuals the metacarpus in length, the process 

 is straight, sharply seri-ated, a little longer than half the metacarpus. The metacarpus 

 is sharply serrated along the hinder margin; the dactylus as in the preceding pair. 



The tkird and fourth pairs (Pl. \TII, tig. 14) are onty a little shorter than the 

 fifth pair. The metacarpus is longer than the earpus, smooth; the dactylus is nearly halfas 

 long as the metacarpus. 



The sixth pair (Pl. VIII, tig. 15) are somewhat longer than the fifth. The femuris 

 laminar, linear, with three small teeth at the loAver anterior corner. The metacarpus is 

 finely serrated along the anterior margin. The dactylus is longer than a third of the 

 metacarpus, smooth. 



The seventlt pjair (Pl. VIII, tig. 16) are short, scarc('ly niore than half as long as 

 the fourth pair; the femur is small, as long as the thi'ee following joints together. 



The pleon is a little longer than the last three pereional segments together; the lateral 

 parts of the segments are deep, evenly rounded. 



The peduncles of the pleopoda are shorter than the rami; the rami are 9- to 10- 

 jointed. 



The second and third coalesced ur al segments are longer than the first; the hinder 

 corners are angular, not produced. 



The peduncles of the uropoda (Pl. ^TII, lig. 17) are longer than the rami, those of 

 the first j^air are serrated along the outer margin. The exteriör rann are a little shorter than 

 the interiör, all finely serrated. 



The telson is obtusely triangulai-, as long as half the last ural segment, and a little 

 longer than half the peduncle of the last pair of uropoda.
