ARION ATER.

shows a neatly-defined yellowish or orange border, rayed with, 

 black lines. 



Avion ater lias a wide range of habitation throughout the temperate 

 and north temperate regions of the Old World. It has not as yet, 

 according to Binney, been transported to America ; but a species 

 very nearly allied to it, A. foliolatus, Gould, has been collected, 

 near Discovery Harbour, Puget Sound. Though nocturnal in habit, 

 A. ater may be occasionally seen in the daytime. Plants are its 

 natural food, but it has not unfrequently been observed to devour 

 earthworms.
