ARION ATER, Linné. 
Generally distributed. Norman remarks that “on the low 
grounds and in damp situations this Arion is always black ; in 
drier situations, hills, and woods, it varies greatly in colour.” 
The var. aterrima, Taylor, the whole body uniformly black, 
which is usually found in mountainous regions, also occurs 
sporadically at low levels. I found two specimens in one of 
the heath plantations near Shapwick Station. In typical 
A. ater the medium area of the footsole is paler than the rest.

In a lane at Stoke Trister, near Wincanton ! 
In my paper in the Journal of Conchology 1 alluded to a 
beautiful variety fuund in a lane at Stoke Trister, near 
Wincanton. Ground colour yellowish white, lineoles 
vivid orange, a broad black band extending the whole 
length of the back, mouth and tentacles also black. 
Foot pale. This large and very showy form which 
apparently comes under Roebuck’s variety albolatcralis 
(see J. C., 1883, p. 39, and Taylor’s Monograph, ii, 
p. 185) was also observed at Dulverton by Mr. Hugh
