Habitat in hortis, campis, nemoribusque vulgatissimé, sub lapi- 
dibus szepissimé latitans. 
Animal rufescent or grey, sometimes freckled or spotted with 
fuscous ; surface slightly sculptured; thoracic dise elongated, 
rounded behind; dorsal carina short, oblique; neck bisulcated 
above. Shell oblong-oval, rather hard, slightly concave. 
This is by far the most common of the British species of 
slug, and is found in woods, fields, and gardens, often hiding 
itself under stones. Length from one to two inches. 
The neck is generally of a red or pale flesh colour, marked 
behind the tentacula with two blackish bands, which are some- 
times interrupted by spots. 
This species, like its congeners, is liable to a vast number of 
variations in colour, and has consequently been divided into a 
vast number of supposed species which pass gradually urto each 
other, and prove them to form but varieties of the same species. 
In the first volume of the Transactions of the Linnzean So- 
ciety, Mr. Hoy has published a paper on one of the varieties 
of this slug, which he has denominated the Spinning Limax. 
In the fourth volume of the same work, Dr. Latham has given 
some additional observations on this subject, made by Montagu, 
with a view to show that this animal has the power to suspend 
itself by a thread, composed of the mucus of its foot ; a cha- 
racter which Mr. Montagu has since assured me, was common 
to all the British slugs.
