AGRIOLIMAX AGRESTIS. WALA 
in the Lower Pleistocene Forest bed at Cromer, in East Norfolk, and also 
from the Upper Pleistocene gravels and brick-earths, 
In France it has been found at the base of the Loéss, in the Pleistocene 
fluviomarine sand (sable aigre) of Menchecourt, near Abbeville, in the 
department of the Somme. 
In Germany, Sandberger reports it from the Middle Pleistocene tufa at 
Cannstadt, Wurtemburg ; and Spiridion Brusina cites it as a Pleistocene 
fossil in Moravia. 
Honocenr.—In Kent, this species has been found in deposits at Buck- 
land, near Dover, by Rev. R. Ashington Bullen ; it has also been tabulated 
or recorded for Maidstone, Charing, Deus Otford, Greenhithe, Exedown, 
near Wrotham, and from alluvium at Seal, near Sevenoaks, by Kennard & 
Woodward. In Surrey, the Rev. R. Ashington Bullen found it abundant 
up to three feet deep in Colley Pit, Reigate. In Essex, it has been found 
in the Lea Valley, at Witham, Braintree, Raine, Roxwell, Shalford, and 
in the alluvium at Walthamstow, according to Kennard & W odie ard, who 
also record the finding of it by Dr. Frank Corner, in Post-Pliocene alluvium, 
at New Park, near the White House in the Lea Marshes. In Berkshire it 
has been found abundantly in beds of the Kennet Valley, Newbury, by Mr. 
E. Perey Richards. 
Mr. G. E. Mason, in 1896, found many specimens of the shell within 
Mitchelstown Cave, Tipperary, mixed amongst the fine red earth on the 
floor of the “Long Cave, ” 600 feet from the entrance. 
In Germany, Sandberger records it from the Léess at Unterdiimbach, and 
Unterzell near Wiirz shure i in Bavaria, and also at Grotzingen near Durlach 
in Baden. It-has also been recorded by Pini from the “alluvium of San 
Fedele, near Milan, in Lombardy, and by von Ihering in the tufa at Streit- 
berg in French Switzerland. 
Variation. — Agriolimar agrestis, though usually offermg a pallid 
colouration, does, under certain environmental conditions, present very 
varied pigmentation, and in this country, according to Dr. Norman, under- 
goes seasonal variation, the individuals though perhaps creamy-white or 
light- drab in the early part of the year, as the summer passes away assuming 
a darker hue, with brown flakes more or less thickly scattered over the sur- 
face, and during the autumn frequently becoming of a rich brown colour. 
The ne to which the species is subject are invariably constituted 
by irregularly distributed dark spots, or blotches, which occasionally more 
or less overspread the whole body, and may at times become accidentally 
ranged into some semblance of longitudinal banding. 
This absence of true banding renders it probable that the various banded 
slugs which have been referred to A. agrestis by various authors, would be 
more correctly allocated with Limax tenellus, L. arborum, or other normally 
banded species. 
According to Dumont & Mortillet, the pale varieties are peculiar to 
forests and ‘shady places, while those living In open situations are always 
darker in colour. 
The variations in size are usually not very striking, but Mr. L. E. Adams 
has observed that those found on the coast ae ays attain a larger size than 
those frequenting more inland localities, and Rev. 8. Spencer Pearce e espe- 
cially remarked upon the diminutive size of specimens found at altitudes of 
7,000 and 8,000 feet in the Engadine, Switzerland, while Kaleniczenko dis-
