DECAPODA FROM ALBATROSS DREDGINGS.

as in most species of Pandalus. The inner lamella is considerably 

 shorter and much narrower than the outer, and lanceolate in outline. 



In the female, the inner ramus of the pleopod is lamellar, about two- 

 thirds as long as the outer, four times as long as broad, and tapered to 

 an acute point. In the male, this ramus is lamelliform, but shorter and 

 very much broader, being ovate and about twice as long as broad. The 

 inner of the two stylets on the inner ramus of the second pleopod of the- 

 male is as long as the other stylet and expanded into broad lamella ob- 

 tusely rounded and ciliated at the tip. 

 The surface of the carapax and pleon is naked but minutely punctate. 

 Three specimens give the following measurements in millimeters :
