SLUGS. TT 
small size of the animal serve to distinguish this 
species. 
I. agrestis 1s common in fields, and abundant 
in cellars and gardens in Portland, Maine; it is 
indigenous to Greenland. 
Limax Brunneus—(the Brown Slug) (Pl. VI., 
fig. 42)—This slug was added to the British 
fauna by the late Dr. Johnston, of Berwick, who 
observed that it differed from every variety of 
Limae agrestis in its darker colour, its colourless 
mucus, in the abrupt termination of the tail, in 
the position of the shield, which is nearly central 
when the animal is fully extended, and in the 
size of the shield, which is as long as the pos- 
terior half of the body; nor is there any keel 
on this part. 
It inhabits shady woods, in damp places, under 
stones, and amongst decaying leaves; and is 
comparatively rare in Berwickshire and in the 
north-east of Hngland; at Thirsk, Yorkshire ; 
woods between Cooper’s Hill and Birdlip, Glou- 
cester (Jones). 
Limax TENELLUS—(the Tender Slug) (PL V., 
fic. 34).—This species finds a place in the list 
of British slugs in that a single specimen was 
found in a wood at Allansford, in Northumber- 
land. The animal is yellow, with the back 
rounded, compressed near the tail; shield 
wrinkled; mucus yellow.
