By the favour of Professor E. B. Poulton, f.e.s., of the Hope Museum of 

 Zoology, and Mr. C. S. Elton, of New College, Oxford, we have had the 

 privilege of studying the CoUembola or Springtails collected by members of 

 the Oxford University Expedition to Spitsbergen, who made extensive 

 collections and observations on the archipelago during the summer of 1921. 

 The localities whence these specimens came are Klaas Billen Bay, Advent 

 Bay, Cape Boheman, and Gips Valley, on the west coast of the large Western 

 Island of the archipelago ; Prince Charles Foreland, a long narrow islet lying 

 alongside the western coast of this island ; and Bear Island, situate somewhat 

 remote from the main Spitsbergen group, nearly 200 miles to the south. 

 The value of this collection is much enhanced by the careful records, not 

 only of the exact localities whence the insects came, but also of the nature of 

 the habitat in which each gathering was secured. These ecological notes, 

 which will, we understand, be further elucidated by members of the 

 expedition, give especial value to the collections. Spitsbergen and Bear 

 Island have been already partly explored faunistically, and we are able to 

 add only two species to the recorded list of CoUembola, one of these being 

 new to science. Of the twenty-one species previously known to inhabit 

 Spitsbergen and Bear Island, eight are represented in the present collection. 

 Very little has been added to our knowledge of the CoUembola of 

 Spitsbergen since the publication of the papers of Schaffer and Skorikow, 

 which both appeared in the year 1900. In these, references will be found to 

 previous literature on the subject. In the present paper we give in the first 

 place a list of the species collected by the Oxford University Expedition, 

 with details of localities, habitat, and dates of capture, adding a few notes as 

 to the general range and geographical importance of the species in each ease. 

 It is unnecessary to incorporate similar details with regard to species not 

 represented in the present collection, but a tabular list of all CoUembola
