The carapace of this species lias three oblique lateral folds 

 and the tclsoii is furnished with five apical s})ines. Lamprops 

 fasciata is very prettily marked. It was somewhat rare in 

 the gathering from the Dogger Bank. 



Diastylis Rathkii (Kroyer).

This is a large and fine species and occurs sometimes in 

 considerable numbers. In the Dogger-Bank gathering it 

 was somewhat scarce. I have on several occasions observed 

 Diastylis Bathkii in the stomachs of fishes.

This species is considerably smaller than the last and was 

 rather uncommon in the gathering.

This was a moderately common form in the Dogger-Bank 

 gathering. The species appears to be widely distributed in 

 the British seas.

This species was common in the Dogger-Bank gathering. 

 It is one of the most important among the Amphipodaas fish- 

 food. Byperia oblivia appears to be more or less frequent
