Disfribution: Murman Coast, Coast of Norway, Skage- 

 rack, Kattegat, coast of Scotland, Iceland, East coast of 

 North America from C-onnecticut as far north as Nova Sco- 

 tia and Prince Edward Island. Thus, this small Hippolyte 

 does not seem to be an Arctic form, but it belongs rather 

 to the Northern parts of the North Atlantic both on the 

 Enro})ean and the American side. 



Smith who has, with bis usnal carefnlness, examined more 

 than a hundred specimens, gives, in bis »Stalk-eyed Crustaceans 

 of the Atlantic Coast of North America north of Cape Cod», 

 details as to the variation in rostrum, telson, and colour. 



The largest specimen (a female carrying Qgg) measured 

 19 mm. According to Smith, it reaches a length of 25 mm.
