Revision of the Amphipoda from South Georgia. 9 
described by MIERS under the name Paramoera australis, a form now 
considered by STEBBING identical with Atylus austrinus BATE. 
The species occurs between tide marks on practically all Subant- 
arctic shores and in some cases in New Zealand it may extend into 
brackish waters. It varies much in size, in the stoutness of the body, 
the presence or absence of the accessory flagellum, the shape of the 
enathopoda and in the telson — some of these variations are discussed 
in the works quoted above, but a full comparison of forms from different 
localities and a fuller knowledge of the sexual differences and of the 
life history is required and a research into these matters would probably 
lead to interesting and important results in connection with the distri- 
bution of the species. 
Apherusa georgiana (Pfeffer). 
Calliopius georgianus PFEFFER 1588, p. 116, pl. 2, fie. 6. 
Apherusa georgiana STEBBING 1906, p. 308. 
I have dissected and examined one of the specimens from the col- 
leetion in the Hamburg Museum and it aerees well wit PFEFFER’S 
description. ] am not quite clear about the structure of the telson in 
this species. The telson of the specimen examined was somewhat damaged 
in dissection and could not be completely made out, but it appears to 
be notched posteriorly, the posterior margin on each side of the notch 
being rounded and bearing a minute setule near the outer side. 
In a tube labelled „Callioprus georgeanus“ there was also one 
specimen of another species that seems to belong to Paramoera though 
apparently differing in several points from P. austrina BATE, and in the 
telson and third uropoda more resembling a Pontogeneia. I have not 
yet been able to satisfactorily identity this second species. 
Paraceradocus miersi (Pfeffer). 
Megamoera miersi PFEFFER 18SS, p. 121, pl. 3, fig. 5.

This is a particularly large species, the males attainng a length 
of 49 mm, and having very large third uropoda. 
It is known from South Georgia, South Orkneys and Graham Land 
(Port Charcot, Booth Wandel and Hovgaard Island and also from the 
South Shetland Islands). It seems to be abundant in these places for it 
occurs in all the collections made there but so far as our present 
knowledge goes it is confined to this portion of the Antarctic Region.
