( H 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 

 pernrission to dissect it and mount the dissections permanently in Canada 

 baisam. By doing so I was able to establish its identity with the form 

 so fully described by CHEVREUX under the name Metopoides walkeri, of 

 which I had specimens from the South Orkneys in the „Scotia" collections. 



Tlüs species is now known from South Georgia, South Orkneys and 

 from Graham Land (Bo.oth 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° V S.. 

 long. 22° W.j 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. 0. WALKER under the name Waldeckia obesa. 



Mr. CHEVREUX established for this species the genus Waldeckia 

 (= Charcotia CHEVREUX L9Ö6) which he considered as coining near to 

 Menigrates A. BOECK ; Mi-. WALKER who had obtained the species in the 

 collections made by the „Discovery" had at first placed it under Socarncs. 

 In niy opinion it comes so near to Orchomenopsis chilensis (HELLER) 

 (== 0. rossi WALKER) that it might almost be placed in the same genus. 

 Stkbbing 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 

 distinct though very short palm and Dr. PFEFFER's and Mr. WALKER's 

 tigures also show a short palm. In any case however the first gnathopod 

 in the species has not the distinctly simple character that it has in Socames 

 and a tendency to the same distal narrowing of the propod is found in
