OLIGOCHAETS OF GREAT BRITAIN AND IRELAND. 



Rev. HILDERIC FRIEND. F.L.S., F.R.M.S. 

 Szi/adlincoie. 



Having made considerable additions to our knowledge of the 

 British Oligochsets during the past year or two, it seems 

 desirable to gather up the references which are scattered among 

 the many Journals to which items have been contributed, and 

 give a bird's eye view of the whole. No attempt had ever been 

 made in this country to tabulate the native species of Annelids, 

 except by myself, till 1909, when Southern published some 

 useful notes entitled ' Contributions towards a Monograph of 

 the British and Irish Oligochasta ' {Proc. Roy. Irish Acad., 

 Vol. XXVII., p. 119, seq.j. This was a valuable beginning, 

 though it did not by any means fairly represent the subject. 

 That list may, however, be regarded as our starting-point. 

 It enumerates, in the author's words, ' 135 British species and 

 sub-species ' (I count 134), belonging (with two exceptions) to 

 six well-known families : as follows : — 



1. .-Eolosomatidie 



2. Naididce 



3. Tubificidas 



4. Lumbriculidse 

 > Enchytraiidffi 

 0. Lumbricidfe 



6 species.

Our following records will be in the same oi'der, as far as 

 possible, thereby enabling the student readily to note the 

 additions made to our knowledge since that list was published. 

 Southern's List stands in ordinary type, the additions being 

 printed in italics, with such supplementary notes and references 

 as mav be found desirable to complete our knowledge. 



I. iEOLOSOMATID^. 



This is the only family which has not, so far as the writer 

 is aware, yielded any new species or locality to the 1909 list.
