Inhab. cellars and clamp places in and near London, 

 Plymouth, and Oxford. 



In spirits, it is dark olive, mantle and back yellow- 

 spotted, sides rather paler ; the number and size of 

 the yellow spots vary in the different specimens ; the 

 young have sometimes a yellowish dorsal streak ; the 

 end of the tail only is keeled, by which it is known 

 from Limax maximus ; and the central band of the 

 foot is generally rather narrower than the side ones. 

 The shell is very like that of Limax maximus, but 

 it is smaller, and the front edge is generally more 

 rounded. 



Lister did not mark this species as English, but 

 this w^as probably an oversight of the engraver. 



When touched, it becomes covered with a white 

 mucus. It has the power of forming a thread, by 

 which it suspends itself from trees, &c. This fact 

 was first noticed by Lister (^Anim. Ang. iii.), and 

 since by Dr. Latham and others {Linn. Trans, i. 

 182. and iv. 85.). 



M. Bouillet and M. Morelet observe that some 

 slugs, as L.Jlavus, lose their colour if they are tor- 

 mented or kept in confinement; iXwxs, L. Jiavus passes 

 from bright yellow to dull olive green.
