Forty-seven specimens were taken from a skeletonizing box 

 November 23, 1911, at the village landing, St. Paul, Pribilof Islands. 

 The types are among these. Other collections were made on 

 November 20, 1911, and May 5, 1912, at the same place.

PONTOGENEIA INERMIS (Krfiyer). 



Two collections of this species were made from the skeletonizing 

 box, March 7 and November 30, 1911. All specimens were females; 

 two on the latter date carrying eggs. The gnathopods are rather 

 robust; otherwise the specimens examined agree with Sars's* 

 figures.
