First antenna about as long as the cephalothorax. Fifth feet of 

 female apparently four-segmented, but consisting really of a two-seg- 

 mented basal part and a two-segmented exopodite. First segment of 

 exopodite long, narrow, with two strong outer marginal setse, and 

 with along pointed projection of its inner edge, which is heavily armed 

 with very short stout spines (tig. 2c). Ter- 

 minal segment twice as long as broad. 

 Fifth legs of male very similar to those 

 of E. velox. 



Remarks. — This species was first de- 

 scribed from specimens collected in asso- 

 ciation with E.affinis, in the St. Lawrence 

 River, between Quebec and Rimouski. 

 The only other report of its occurrence 

 was made by Dr. L. W. Williams in 

 1906, when he mentioned its presence in 

 tows made in Narragansett Bay, Rhode 

 Island, near Wickford. Found very 

 sparingly by the writer in a surface tow
