Tlie following list includes all the Neniatoccrous Diptera 

 Avliich have hitherto been recorded from Bear Island and 

 Spitsbergen, and notes also such of these species as have 

 been recorded also from other parts of the Arctic region, the 

 following abbreviations being used : B, Bear Island ; S, 

 Spitsbergen and adjacent islands; J, Jan Mayen; I, Ice- 

 land; G, Greenland; N, Nova Zeml ya ; L, Lapland. 

 Allowing for probable synonymy (as indicated sn])sequently 

 in the text) the list comprises 54 species, 29 of which 

 (marked ^) are re])resented in the Oxford University collec- 

 tion. Of these 29 species, 9 (marked t) are recorded from 

 the islands for the first time, G of these 9 being described 

 as new. It is highly probable that, wlien the North- 

 European Chironomid fauna is more precisely known, some 

 of the species described by me, and also by Kieffer and 

 Holmgren, from Bear Island and Spitsbergen, will prove to 

 be identical with European forms, hut in the present un- 

 satisfactory state of our knowledge of these flies the identity 

 can only be established in a few cases. I have not attempted 

 to study all the very numerous descriptions of Palaearctic 

 species published by Kicffer, and it is therefore possible that 

 some of my supposed new species may be found among 

 these. ^ 



It w'ill be seen from the list below that of the 55 species 

 recorded, 35 are known from Spitsbergen but not from 

 Bear Island, 15 from Bear Island i)ut not from Spitzbergen, 

 and only the remaining 5 from both places. The wide 

 differences which these figures seem to indicate between the 

 faunas of the two regions would no doubt become very much 

 less apparent by further collecting in both areas. Since 

 some species {Sciara tridentata and A'edeii alpmus) are 

 known from Spitsbergen and Greenland, it seems very 

 probable that they (and other Spitsbergen species) will 

 eventually be found on Bear Island also : —
