Limacellus variegatus. Turton, Man. ed. 1. t. 3. 

 f. 16. (Shell.) 



Inhab. cellars and damp 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 was probably an oversight of the engraver. 



When touched, it becomes covered with a white mu- 

 cus. It has the power of forming a thread, by which 

 it suspends itself from trees, &c. This fact was first 

 noticed by Lister (Anim. Aug. iii.), and since by Dr. 

 Latham and others (Linn. Trans, i. 182. and iv. 85.). 



* * * Mantle short, truncated behind ; shell oval, thick, 

 convex beneath. 



13.3. LIMAX carinatus. Keeled Slug. Yellowish, tes- 

 sellated with brown ; head and tentacles black ; 

 mantle granulous and with a furrow near its mar_ 

 gin ; the ridge or keel of the back very obvious, 

 and of an amber colour; the sides pale; shell 

 oval, often thickened, and very convex beneath, 

 (t. 1. f. 15.)
