 A specimen previously reported from Sitka, Alaska, proves to be P. hirsutius- 

 culus, and Holmes 's record thus becomes its northern limit. 



Biological Survey of San Francisco Bay. — Pagurus samuelis is 

 apparently of very exceptional occurrence in San Francisco Bay, very 

 unlike the closely related P. hirsutiusculiis. The only specimen of P. 

 samuelis found was in a lot of twenty-five P. hirsutiusculiis gathered
