3. A. HORTEN'SIS,* FERUSSAC. PL. VI. 



Body much smaller and more slender than that of A. ater, 

 varying in colour from black to brown, rufous, yellowish, grey, 

 or greenish, usually striped or banded longitudinally, tubercles 

 oblong, close-set, coarse ; mantle usually with a dark band 

 round its margins and down the middle ; tentacles slightly 

 swollen at their tips ; foot with a narrow border of grey, yellow, 

 orange, or rufous-colour ; slime of a whitish or yellowish colour. 

 Length, about an inch and a half. 



Shell consisting of granules which are cemented together in 

 a somewhat oval- shaped mass. 



This slug is tolerably active. The breeding season 

 extends from May till September ; the eggs which are 

 from fifty to seventy in number, are said by Bou- 

 chard-Chantereaux to be phosphorescent for fifteen 

 days after they are laid, and the young, which are 

 excluded in from twenty to forty days, arrive at 

 maturity towards the end of the first year. This 

 species may be distinguished from A . ater by its much 

 smaller size, by the longitudinal stripe with which it is 

 usually marked, and by the testaceous granules being 

 united instead of separate. 



Inhabiting gardens.
