XL. — Notes on CoUemhola. — Part 4. The Classification of the 

 Collembola ; ivith a List of Genera known to occur in the 

 British Isles. By John Wi Shoebotham^ N.D.A,, Berk- 

 hampstedi, Herts. 



In ray paper ou "Some Irisli Collembola" (19l4), p. 59, 

 I remarked that the classification adopted was one which, 

 in the main, had been accepted by authors for the previous 

 seven years, and that Dr. Borner had recently proposed a 

 new system on which I should make some notes. 



This paper was practically completed during the early 

 part of 1914, but my unexpected call to South Africa 

 prevented me publishing it, and I then intended waiting till 

 I returned to England. However, as I am about to publish 

 a preliminary account of the Collembola of Lancashire and 

 Cheshire, I feel it is just as well to list them according to 

 the new system, which is much to be preferred to any yet 

 proposed. I therefore give liere a translation of part of 

 Borner''s paper (1913 A), pp. 318-322, which forms a key to 

 the new classification, and I append a list of the genera of 

 Collembola hitherto found in the British Isles. 



My best thanks are due to Dr. A. D. Imms, of the 

 University of Manchester, for kindly seeing this paper 

 through the press and for criticisms and suggestions, and to 

 Mr. T. A. Coward, also of Manchester University, for much 

 kind assistance.
