GASTEROPODA. LIMACID®. 49 
The first variety is very generally diffused ; the second is far 
from being common, and is found with var. 1; the third variety 
is very abundant in the West of England, especially on the 
borders of granite districts, where it is to be found beneath 
stones during the day. The fourth variety I found on a heath 
in Cornwall, near Bodmin, in company with var. 1 and3. The 
fifth variety is confined to chalky districts: I have twice re- 
ceived it alive from Mr. J. E. Gray, who found them near Dart- 
ford, in Kent. 
Had my friend De Férussac seen the modification of var. ¢ 
with oblique lines on the lateral margin, I am confident that he 
would then have considered his aléus as a variety of Hmpiri- 
corum. 
2. ARION HORTENSIS. 
A. niger, longitudinaliter griseo-fasciatus ; pede griseo luteo 
aut croceo. 
Arion hortensis, Féruss. Hist. des Moll. 65. pl. 2. fig. 4-6. 
Habitat in hortis, vulgaris. 
Black, longitudinally banded with grey ; foot grey, luteous, 
or saffron-coloured. Length two inches. 
General form when in motion cylindric. Head smooth above, 
with two impressed longitudinal lines between the upper tenta- 
cula, which are rugose above. Thoracic dise granulated ; the 
granules sometimes confluent. Back sculptured with elongate 
linear rugee, which are tolerably regular, and slightly rounded 
before and behind. Foot perfectly smooth. 
Viewed with the lens, the whole of the thoracic disc, the 
back and sides of the abdomen, are very minutely sprinkled 
with luteous, tinted with saffron. The thoracic dise has two 
longitudinal bands of grey, between which the general colour is 
less intense than it is laterally. The back of the abdomen has 
a longitudinal grey band on each side; and the sides of the 
abdomen on their lower edge are greyish white. The tentacula 
are sometimes very faintly tinted with bluish. The foot is 
generally sprinkled with minute testaceous dots. 
This species is very common in all the kitchen gardens round
