LTLJEBORGIA PALLIDA. 205 



took several specimens on the eastern side of Drake's 

 Island. 



In the living animal the colour is very white, the 

 back being stained with a rich crimson blotch, a circum- 

 stance that enabled us to identify every specimen at once. 

 The hands possess a rosy hue, and a tinge of the same 

 colour may be detected on many of the articulations of 

 the legs. 



Bruzelius, in his " Memoir on the Amphipoda of Skan- 

 dinavia," has given the figure and description of a species 

 of this genus, under the name of Gammarus brevicornis, 

 which we consider to be identical with this, the only 

 distinction being the shortness of the last joint of the 

 peduncle of the lower antennae, the greater relative 

 length of the flagellum, and the less ornate character 

 of the serrature of the fingers to the hands, the result 

 probably of being examined with a less powerful lens. 

 The specimens, described by Bruzelius, were taken on 

 the western shores of Sweden.
