1 N 1 882 s - the < rerman Expedition to South Georgia for the Observa- 

 tion of the Transil of Venus made a collection of the Crustacea of thal island 

 which was afterwards examined bj Dr. GEORG PFEFFEB and described 

 in a series of valuable papers published in 1888. The collection was an 

 important one as it was practically the firsl extensive collection to be 

 t'ully reported upon from a region near the Antarctic Continent 



Of the Amphipoda, with which alone we are concerned ai present, 

 I >!•. PFEFFEB 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 thal time when the 

 knowledge of the Amphipoda was not very far advanced it was natura] 

 enough to consider these forms from an entirely new locality to be all 

 new species. Subsequenl research however has shown that in a few cases 

 the species had been already described from elsewhere; on the otherhand 

 several of the species have since been placed in other genera or have 

 been redescribed and renamed by authors who overlooked or were ignoranl 

 of PFEFFER's work. ünfortunately PFEFFER's paper appeared onlj a 

 very sjiort time before the publication of STEBBlNG's reporl on the 

 „Challenger" Amphipoda too late for Mr. STEBBING to make füll |ise 

 of it in thal report. 



In tlie examination <>( the Amphipoda collected by the Scottish 

 National Antarctic Expedition, most of which are from the South Orkneys, 

 it was necessary Cor nie to compare them with those described bj F*FEFFEB 

 Erom South Georgia, and upon my expressing a desire to see co-types of 

 his species, Dr. G. PFEFFEB and Dr. 0. STEINHAUS mosl generously placed 

 freelj at my disposition the whole Soutli Georgia collection in the Hamburg 

 Museum. 1 have thus been enabled to compare the Soutli Georgia specimens 

 with those from several pari- of the Antarctic, for in addition t<» the 

 „Scotia" collections I have had an opportunity, through the kindness of 

 l>r. W. T. CALMAN, of the British Museum, of seeing anything thai I 

 wished from the collections made l>\ the „Southern Cross" and the „Disco- 

 very" Expeditions.
