126 CATALOGUE OF THE MOLLUSCA 
excellent little work, “ Historia Molluscorum Sueciz.”* Wishing 
to have the opinion of the Rev. B. J. Clarke, whether this was 
the young of any of the species he has so admirably described, 
we sent him a drawing and description of it. Mr. Clarke states 
that but for the black tentacles he would have thought the 
drawing to represent the young of Limax flavus, but taking the 
description into consideration, he thinks us justified in consider- 
ing it distinct. The blue tentacles are a permanent character in 
L. flavus, and M. Bouchard Chantereaux says that its mucus is 
colourless. 
6. L. agrestis, Linn. 
Liman agrestis, Gray Turt. Man. 117; Clarke in Ann, 
Nat. Hist. xii. 338, t. 12, f. 13. 
In fields and gardens; much too common. 
7. L. srunnevs, Drap. 
Limax brunneus, Johns. in Berw. C. Proc. i. 154; Gray 
Turt. Man. 117. 
In damp woods, frequent. 
This species was introduced into our Fauna by Dr. Johnston, 
and considered to be the Z. brunneus of Draparnaud, partly, per- 
haps, in conformity with our opinion. Draparnaud’s species, 
however, is very obscure, and was unknown to Férussac. M. 
Bouchard Chantereaux finds a species in the north of France, 
which he considers to be the Z. brunneus. His description of 
it agrees pretty well with our animal, but a comparison of the 
specimens would be necessary to pronounce on their complete 
identity. It is quite distinct from the dark variety of Z. 
agrestis. 
*As this is the first time the species has been noticed as British, we insert 
Nilsson’s description :—‘* Animal parvum, vix 1} une. longum. Clypeus lineis 
subtilibus concentricis striatus, apertura laterali postica. Collum supra linea 
longitudinali elevata, lateribus subreticulatis. Dorsum posticé compressum. 
Color clypei et dorsi postici luteus; dorso supra luteo-virescente levissime 
cinerascente, subtus albo. Tentacula, caput, et linea colli utrinque nigra. 
Mucus luteus. Habitat in sylvis inter folia putrescentia, humida, rarius.”— 
Nils. Hist. Moll. Suec. 10.
