in the Hamburg Museum.

In 1582—83 the German Expedition to South Georgia for the observa- 
tion of the Transit of Venus made a collection of the Crustacea of that island 
which was afterwards examined by Dr. GEORG PFEFFER and described 
in a series of valuable papers published in 1888. The collection was an 
important one as it was practically the first extensive collection to be 
fully reported upon from a region near the Antaretic Gontinent. 
Of the Amphipoda, with which alone we are concerned at present, 
Dr. PFEFFER distinguished thirteen (13) species, all considered new, and 
with the exception of one, which was figured only, all of these were 
described and figured in considerable detail. At that time when the 
knowledge of the Amphipoda was not very far advanced it was natural 
enough to consider these forms from an entirely new locality to be all 
new species. Subsequent research however has shown that in a few cases 
the species had been already described from elsewhere; on the other hand 
several of the species have since been placed in other genera or have 
been redescribed and renamed by authors who overlooked or were ignorant 
of PFEFFER’s work. Unfortunately PFEFFER’s paper appeared only a 
very short time before the publication of STEBBING’s report on the 
„Challenger“ Amphipoda — too late for Mr. STEBBING to make full use 
of it in that report. 
In the examination of the Amphipoda collected by the Scottish 
National Antaretie Expedition, most of which are from the South Orkneys, 
it was necessary for me to compare them with those described by PFEFFER 
from South Georgia, and upon my expressing a desire to see co-types of 
his species, Dr. G. PFEFFER and Dr. O. STEINHAUS most generously placed 
freely at my disposition the whole South Georgia collection in the Hamburg 
Museum. I have thus been enabled to compare the South Georgia speeimens 
with those from several parts of the Antaretie, for in addition to the 
„Seotia“ collections I have had an opportunity, through the kindness of 
Dr. W. T. CALMAN, of the British Museum, of seeing anything that I 
wished from the colleetions made by the „Southern Cross“ and the „Disco- 
very“ Expeditions.
