a tree. August was also a busy month, and resulted in (10) 

 Bimastus eiseni, Levinsen, which Benham reported as being new 

 to Britain. I found L. castaneus and A. chlorotica on Cross 

 Fell, and several of the foregoing in other localities (see "Earth- 

 worms of the North of England " in the ' Naturalist,' January, 

 1891). Though I left Carlisle in 1891, I have collected in 

 Cumberland at frequent intervals since, and in April, 1899, 

 recorded A. longa, A. caliginosa, A. chlorotica, L. ruhellus, and 

 Allurus tetrcEdrus from the Cockermouth and Keswick district. 

 I added (11) Dendrohcena suhruhicunda, Eisen, and (12) D. mam- 

 mails, Sav, (=^. celtica, Eosa), which I had found at Langholm 

 in 1890. I found near the Art School and station at Keswick 

 (13) Octolasium lacteum, Oerley, and several of the foregoing on 

 Latrigg, Catbells, and elsewhere, besides discovering many inte- 

 resting Enchytraeids and waterworms, which will be reported 

 later. 



In February and March, 1911, I visited Cumberland again, 

 and made careful investigations for both the terrestrial and fresh- 

 water forms. At Brougham I found (14) Octolasium cyaneum, 

 Sav., as well as A. chlorotica, A. longa, L. terrestris, L. ruhellus, 

 L. castaneus, A. turgida, D. mammalis, and D. arborea. On the 

 way to Newton Moss I discovered (15) Lumbricus festivus, Sav. 

 (= L. rubescens. Friend), as well as A. chlorotica, A. longa, L. 

 terrestris, L. ruhellus, L. castaneus, Allurus tetnsdrus, and D. 

 mammalis, while I added (16) Eisenia rosea, Sav., to the list. I 

 had the further pleasure of finding (17) Octolasium gracile, Oerley, 

 at Caldewlees, not far from Carlisle. 



It is interesting to note that D. suhruhicunda was found at 

 2800 ft. on Skiddaw, that a peculiar variety of A. chlorotica 

 occurs on the shores of Bassenthwaite Lake (perhaps = L. ana- 

 tomicus of old authors), and that a golden form of Allurus {luteus, 

 Friend) occurs in the Caldew at Cummersdale. L. ruhellus is 

 found at sea-level at Silloth, and on the top of Penrith Beacon. 

 The district, owing to its mountains and lakes, streams and 

 estuaries, is peculiarly rich in the lesser forms, and, though I 

 have done a good deal of research among these, much remains to 

 be done. Total number of earthworms thus far recorded, 17.
