Of this species the South Georgia collections at Dr. PFEFFER’S disposal 
contained originally only three specimens not well preserved. I was able 
to examine a specimen still in the collection and by Dr. STEINHAUS’s 
permission to disseet it and mount the dissections permanently in Canada 
balsam. By doing so I] was able to establish its identity with the form 
so fully described by CHEVREUX under the name äMetopordes walkeri, of 
which I had specimens from the South Orkneys in the „Scotia“ collections. 
This species is now known from South Georgia, South Orkneys and 
from Graham Land (Booth Wandel Island).

The specimens of this species examined and described by Dr. PFEFFER 
did not belong to the official collection and were not deposited in the 
Hamburg Museum. Fortunately in the „Scotia“ collections there were 
several specimens from the neighbourhood of Coat’s Land, Lat. 74° 1’ S., 
long. 22° W., which by the great dilatation of the body and especially 
by the character of the dorsal process on the first segment of the urus 
are without doubt the same as the species described by PFEFFER. 'The 
species is also identical with the form more recently described by 
Mr. CHEVREUX and Mr. A. Ö. WALKER under the name Waldeckia obesa. 
Mr. ÜHEVREUX established for this species the genus Waldeckia 
(— Charcotia CHEVREUX 1906) which he considered as coming near to 
Menigrates A. BOECK; Mr. WALKER who had obtained the species in the 
collections made by the „Discovery“ had at first placed it under Socarnes. 
In my opinion it comes so near to Orchomenopsis chilensis (HELLER) 
(= 0. rosst WALKER) that it might almost be placed in the same genus. 
STEBBING had identified his Orchomene cavimanus with it and placed it 
under Orchomenopsis. The only points in which it appears to differ from 
the typical species of Orchomenopsis are that the first gnathopoda are said 
to be not subcheliform and that the peraeopoda bear one or two accessory 
branchial lobes. The propod of the first gnathopod does certainly narrow 
very considerably distally but in my specimens there is still a fairly 
distinet though very short palm and Dr. PFEFFER’s and Mr. WALKER’S 
figures also show a short palm. In any case however the first gnathopod 
in the species has not the distinetly simple character that it has in Socarnes 
and a tendency to the same distal narrowing of the propod is found in
