Tlie Caprellidae seem to be altogether abseilt from the shores of 

 the Antarctic continent and only very scantily represented on those of 

 Subantarctic Lands. 



Polycheria antarctica (Stebbing).

A small specimen of this species from South Georgia was in the 

 collections of the Hamburg Museum but had not been identified. 



I have discussed this species at considerable length in my report 

 on the „Scotia" Amnhipoda and after an examination of types or nanied 

 specimens of most of the species described have come to the conclusion 

 that they must all be considered as belonging to the one species originally 

 described by STEBBING as Dexamine antarctica though there is much 

 Variation in the dorsal processes on the pleon, in the shape of the side 

 plates, of the gnathopoda and in the size of the eyes. 



The species appears to be primarily an Antarctic species, being 

 found at South Victoria Land, Kerguelen Island, South Georgia, and 

 South Orkneys, but it also extends far to the north, occurring in Australia. 

 New Zealand, and South Africa, while in the Indian Ocean it is found in 

 several places and reaches to Ceylon and in the Pacific it occurs as far 

 north as Puget Sound.
