Hansen, in liis admirable monograph of the Cirolanidfe, 

 has ennmerated very critically all localities where this spe- 

 cies has been obtained. Thus it bas been found imdonbtedly 

 on the coasts of Norway, at least as far X. as the Trond- 

 hjem Fjord (Gr. O. Särs, LiLLjEBORtt), of Shetland Isles (Nor- 

 man), of England (Bate & Westwood), of Bretagne (Bonnier), 

 of Italy and Naples (Hansen) and off the Atlantic coast of 

 North America (Harger). Thus, it seems to be mainly an 

 inhabitant of the North Atlantic. As yet it has not been 

 found pelagic, but in depths varying from 30 — -40 to 200 — 300 

 fathoms. It is, according to Särs, one of the most voracious 

 crustaceans excelling in this respect even Anomjx among the 

 amphipods.

Chiridothea megalura was observed the iirst time during 

 the cruise of Vöringen» in the year 1876 at two stations 



^ Ought to be ■\vritten Idotliea, not Idotea, as derived from EiSo&ta, the 

 daughter of Proteus.
