70 BULLETIN OF THE 



developed into a broad oval lamella about a third as long as the outer ramus, 

 with both margins setigerous and the inner thickened and bearing a Blendei 

 stylet armed as usual with minute hooks. The inner ramus of the appendage 

 of the second somite bears the two stylets usually characteristic of the male. 



A small and imperfect female specimen appears not to differ from the males 

 as above described except in the usual sexual characters. The inner ramus of 

 the first abdominal appendage is a very small lamella nearly four times as long 

 as broad and furnished with very long and slender setae. 



The surface of the carapax and abdomen is very nearly naked, but is rough- 

 ened by minute granular projections. 



The number and structure of the branchiae seem to be essentially the same 

 as in the typical species of Pandalus, but there is apparently no epipod at the 

 base of the fourth leg, so that the branchial formula is as follows : —

Young male. — The carapax is slightly compressed, and including the rostrum 

 only a little shorter than the abdomen ; the dorsum is rounded posteriorly, but 

 carinated in front of the middle, and rises anteriorly into a high and sharp crest
