 tentacles short, nearly smooth ; the lower pair are mere tuber-

 terminate the larger or upper tentacles : mantle wrinkled 

 lengthwise when the slug is crawling, and tuberculous when 

 it is at rest and bunched up : respiratory opening on the right

HABITAT : Under leaves and in damp places ; widely distri-

Active and crawls under water. In captivity feeds greedily 

 on the slime of its companions for want of its usual nourish- 

 ment, which consists of lichens, fungi, and decaying vegetable 

 matter. As my friend Mr. E. J. Lowe well observed, this is 

 more tender than A. liortensis, which is remarkably tough and 

 difficult to crush.
