Limaz variegatus occurs in cellars, caves, and old buildings ; 
likewise in gardens and fields beneath stones. The tentacula 
are blue, the under ones of a paler hue. Head with two longi- 
tudinal excavated lines, generally punctulated on each side with 
dark brown or blackish. The dise of the thorax is of a deeper 
colour than the rest of the body, and is elegantly spotted with 
clay-yellow or croceous. It is sculptured very beautifully with 
subconcentric elevated lines. Sides of the thorax and foot 
without spots. Back variegated, the sculpture elongated, at- 
tenuated before and behind, but not acutely. Keel croceous, 
very rarely luteous. Foot grey, whitish, or luteous. 
This beautiful species, which is by no means uncommon in 
the environs of London, does not appear to be abundant in 
other parts of Britain: itis rare in Devonshire. I once received 
a specimen from my friend Professor Buckland, who found it 
near Oxford. Length two and a half inches. 
Shell thin, concave, mamillated at its posterior extremity 
externally. 
De Férussac quotes the Limax flavus of Linné and Pennant 
for this species; but as Linné quotes Lister’s descriptive cha- 
racter *, which does not apply to L. variegatus ; and as Pennant 
* “ Limax succinei coloris, albidis maculis insignitus.’’ List. exerc. Anat, 
j. t. 1; Linn. Syst. Nat. xii. i. 1082.
