We have received from the Eev. A. M. Norman a specimen 

 that probably belongs to this species. It differs little from 

 A. helliana, except in the absence of the ornate character of the 

 posterior margin of the third segment of the pleon, and in 

 having the superior antennae attached to the lower angle of 

 the anterior margin of the cephalon. 



It was taken off the coast of Durham. Lilljeborg obtained 

 his specimen at KuUaberg, on the coast of Norway.
