flesh-coloured, mottled with darker brown. Length of adult animal reaching 

 to 26 mm. 



Remarks. — This species was first described by Prof. Lilljeborg under the 

 above name from specimens taken off the west coast of Norway. The form sub- 

 sequently recorded by Sp. Bate & W'estwood from the British Isles as C. sjnnipes 

 is undoubtedly the same species. It is nearly allied to the Mediterranean form, 

 C. neglecta Hansen, though differing in its more elongated body, the smooth coxal 

 plates, and the form and armature of the terminal segment of the metasome. 



Occurrence. — The species occurs along the whole south and west coasts 

 of Norway, at least to the Trondhjem Fjord, and is not infrequently taken up in 

 the dredge together with other animals. I had, however, no idea of the great 

 abundance of this form, until 1 tried another method of catching it, viz., small 

 weels baited with dead fish. By these means, I have taken it in extraordinary 

 numbers, and in one night, all the soft parts of the bait were generally 

 completely torn off by them, so as to leave only the skeleton. Subsequently I 

 have also taken it in great abundance in the Trondhjem Fjord, from dead fish 

 fastened on the [fishing lines. Indeed, it seems to be one of the most effective 

 scavengers of the sea, excelling in this respect even the most voracious species of 

 Anonyx among the Amphipoda. 



Distribution. — British Isles (Sp. Bate), Kattegat (Meinert), Shetland Isles 

 (Norman), coast of B'rance (Bonnier), Mediterranean at Naples (Hansen), Atlantic 

 coast of North America (Harger).
