DISTRIBUTION OF BRITISH ANNELIDS. 191 



1903, eleven species of earthworms and two or three Enchytrseids. 

 These included (1) Lumhricus terrestris, L. ; (2) L. riibellus, 

 Hoffm. ; (3) Octolasium cyaneum, Sav. (or 0. lacteum, Oerley) ; 

 (4) Eisenia foetida, Sav. ; (5) Dendrobcsna subrubicunda, Eisen ; 

 (6) Aporrectodea chlorotica, Sav. ; (7) Allolobophora caliginosa, 

 Sav.; (8)^. loiiga, JJde; (9) Eisenia rosea, Sav.; (10) Dendro- 

 bcena boeckii, Eisen (= L. octoedra, Sav.), a rare worm in most 

 parts of England ; and (11) Allurus tetrcedrus, Sav. 



September 17th, 1910, digging in my garden at Swadlincote, 

 in South Derbyshire, I found A. longa, Ude, very common, 0. 

 cyaneum, Sav., a little less so ; L. terrestris, L., more rare, and 

 L. rubellus, Hoffm., but seldom. October 29th, when going into 

 the country, I found (12) Lumbricus castaneus, Sav., and (13) Den- 

 drobcena mammalis, Sav. (= celtica, Kosa), while I further found 

 the latter at Smisby in April, 1911, plentifully, and provided 

 with spermatophores. Nearly all the worms found in the Peak 

 District I found also in this neighbourhood, while (14) Dendro- 

 bcena arborea, Eisen, is found wherever one meets with decaying 

 tree-stumps. Allurus and A. chlorotica are common everywhere. 

 On April 14th I found a worm at Swain's Park Crossing, which 

 I at first took to be Bimastus eiseni, Levinsen. It proves, how- 

 ever, to be a new British worm, and, as it seems to be also new 

 to science, I have named it (15) Dendi'obcena merciensis. As my 

 present district lies at the boundary of three or four counties, it is 

 difficult at times to say exactly to which a specimen is to be 

 referred. Hence the Leicestershire list may be compared with 

 the one from Derbyshire, and those of Stafford and Warwick. 

 Present record, 15 species.
