20 LIMACIDiE. 



five lines long, very tliin, nearly oval or oboval, white, 

 much arcuated in front, tolerably straight behind, neither 

 attenuated, nor rounded, but blunt, at the base ; its apo- 

 physis of adhesion is rather prominent in the more cha- 

 racteristic examples, and situated rather behind the 

 middle. 



In his account of the anatomy of this species, Mr. 

 Nunneley mentions that it possesses an additional loop 

 of intestine, in other respects its internal organization 

 is closely similar to that of cinereus. Its eggs are not 

 quite so large. 



The cellar-slug inhabits damp places in houses, espe- 

 cially vaults. It is found in most of our great cities, and 

 is, probably, generally dispersed through our towns, large 

 and small. It is a gregarious species.

This little noticed slug was first added to our tauna 

 by Dr. Johnston of Berwick. It appears to be not un- 

 common, according to Mr. Alder, in the damp woods 

 of the north-east of England. Our figure was commu- 

 nicated by Mr. Alder, who remarks that it is quite dis- 

 tinct from its near ally Limax agrestis, and very constant 

 in its characters. It is a very small species, about 

 or less than an inch in length when crawling. It is
