SOME JERSEY OLIGOCH.MTS. 457 



from just the border of the beach where fresh water was 

 dripping ; some from a cave in Devil's Hole. The match-box 

 contains a collection from the shore of the lake, the west and 

 north generally, and the banks of a small stream running into 

 Devil's Hole. I spent a whole day on this run on a cycle, and 

 sorted out the worms as I got them, instead of waiting until I 

 got back, and am under the impression there is a big number in 

 the small space." 



The surmise proved to be correct, as the following notes will 

 show : — 



Geneeal Eesults. — Seeing that this is the first attempt to 

 deal in a systematic way with the Annelid fauna of any of our 

 islands,* the results are of peculiar interest. Nearly fifty 

 different species of Annelids reached me in Mr. Hillman's 

 collection, and, when these are added to the species already 

 known, we obtain the ensuing : — 



Family. No. of Species. 



Lumbriculidce . . . ... .... ... .... 1 



Enchytrceidce ... ... .... ... ... 31 



Megascolecidce .... .... .... ... 1 



Lumbricidcs ... ... ... .... ... 17 



If we analyse the Enchytraeids, we find their number 

 represented thus : — 



Genus. No. of Sp. 



Genus. 



No. of Sp. 



Buchholzia ... 1 



Chamcedrilus 



1 



Mesenchytrcsus 2 



Pachydrilus 



2 



Henlea ... 4 



Enchytrceus 



4 



while the species of Fridericia numbered sixteen at least. 

 Though a strict account was not kept from the very beginning 

 of each specimen of Enchytra^id examined and identified, the 

 figures which follow give a good idea of the relative frequency 

 of the different species. 



Buchholzia was represented by three specimens, all immature, 

 and Chamcedrilus by five, also in an immature condition. 



* Mr. Southern has dealt with Clare Island for the Irish students of 

 Nature in a similar way. See Bibliography.
