Color a pale straw yellow. As seen from the side (fig. 1), the 

 shell of the male is oblong, dorsal margin gently curved ; ventral 

 margin slightly sinuate, posterior margin obliquely truncate, thus 

 forming an angle at the infero-posterior margin. The anterior sinus 

 is ciliate, widely opened, the anterior extremity produced much be- 

 yond the sinus. 



Secondary or grasping branch of the second antenna of the male 

 (fig. 2), with its terminal segment long and narrow, twelve to four- 

 teen times as long as wide, curved, and reflexed against the second 

 segment, thus forming a grasping organ, and with a short ringed 

 seta near its point of union with the second segment. Second segment 

 bent backwards, and with three-ringed seta; of nearly equal length 

 situated along its inner margin. 



One specimen was sent to the U. S. National Museum, which was 

 collected by Dr. J. Schmitt from off the coast of Anticosti Island, 

 Gulf of St. Lawrence, Ace. No. 3911)3. 



Distribution. — British coasts (Brady and Norman, 1896), Hol-

 bors (Norman, Sars, Lilljeborg).
