 Hob. — Europe, Syria, Madeira (about outhouses and in cellars, in gardens 



and on walls, under hedges and logs of wood). 



This very handsome leopard-spotted slug was the first to attract 

 the attention, nearly two centuries ago, of our famous countryman 

 Dr. Martin Lister, of Oxford, in whose ' Historia Animalium Anglias' 

 it is accurately figured and described. It is the largest of the tribe, 

 conspicuous for its elongately tapering eel-like form, and is plenti- 

 fully distributed throughout Europe about outhouses and in cellars, 

 under hedges and logs of wood, in gardens and on walls. The shield, 

 it will be observed, is rather ample, rounded in front, and terminating 

 in a sloping angle behind. The surface of the shield is striately 

 wrinkled in a concentric manner, and the respiratory orifice is at 

 the posterior extremity of the right margin. Below the shield, the 

 body is longitudinally wave-wrinkled throughout, being at first 

 rounded on the back, and then gradually keeled. The tentacles are 

 unusually long, partaking of the slenderness of the body. 



The spotted variety, from which our figure is drawn, a specimen 

 collected for its size and beauty, by Mr. Metcalfe, at the little 

 island of Herm, may be regarded as the type of the species ; I have, 

 however, collected it as large and as beautifully spotted in my own 

 garden. While examining some living specimens, I met with a 

 curious instance of mucus-spinning. In the course of the evening, 

 one escaped from a glass on the mantelpiece, and having made its 

 way to the edge of the marble, was observed to let itself down by a 

 thread of mucus a distance of from three to four feet, into the 

 fender. The time occupied was about five minutes. 



The shell of L. cinereus is the largest and most symmetrically 

 developed of the genus ; it is of an oblong square form, regularly 

 concentrically enlarged from an umbonal nucleus, depressly concave, 

 tinged with a blush of pink, membranaceous at the outer edge.
