SOME EAST SUSSEX OLIGOCH^TS. 

 By the Rev. Hilderic Friend, F.R.M.S. 



While treating of the distribution of British Annelids (1) * 

 in this Journal, I gave in April, 1913 (vol. xvii., ser. 4, pp. 151-2), 

 a list of the Lumbriciclce of Sussex. In the same volume I 

 also described some new species of Henlea (pp. 81-91), while in 

 other articles in the ' Zoologist ' and the ' Journal of the Royal 

 Microscopical Society ' I had added still further to our knowledge 

 of the subject. Up till the present, however, no attempt has 

 been made to bring under review our knowledge of the entire 

 order of Oligochsets. As I have, so far as I am aware, been the 

 only naturalist to study the subject, the following records are 

 entirely based on my own observations in the county. 



It will be necessary, for the sake of completeness, to re- 

 capitulate some of my earlier statements (7). My researches 

 commenced in November, 1890, and were continued in March, 

 1892 (2). The Lumbricidce collected on these occasions numbered 

 fifteen species. In addition, a number of Tubificidce and En- 

 chytrceidcs were examined, but many of these have not as yet 

 been reported on. 



In 1897 I compiled a list of Sussex Earthworms (3) so far as 

 then known, and enumerated sixteen species ; Octolasium pro- 

 fugum being the latest addition to the county records. For 

 many years, owing to my residence at a distance and my other 

 researches, no further progress was made, but in 1911 Helodrihis
