LAND AND FRESH-WATER SHELLS. 161 



I am not aware of its having been found here previously to the discovery of it 

 this winter. It was found in Messrs. Veitches' nursery, by one of the men when 

 digging a piece of ground; and knowing that I was curious in these matters, 

 he gave one to me, and a fine specimen it is. The same parties met with several 

 others, but much smaller than the first; I have found them myself some ten 

 years ago, in the Durdham Down nurseries at Bristol, which is, I believe, 

 the first place they were found in in this country: they were supposed to have 

 been imported with some plants from Teneriffe. 



Helix aspersa is very much too common. H. hortensis is very abundant 

 also; I met with what I consider a curious variety of this species, the body 

 of the animal, yellowish green; foot on the upper sides, dark greenish yellow, 

 darker towards the margin, the bottom of the foot black; the long tentacles, 

 pale yellow; short ones, nearly black; eyes, black. The shell of this variety 

 is about the size of H. hortensis^ of a pale yellow colour, precisely like the 

 yellow variety of that species, but my variety differs in having a brown polished 

 mouth. The animal, as you will observe, too differs very much in colour 

 from H. hortensis; can it be a hybrid between H. hortensis, and H. nemoralis? 

 Helix arbustorum is not common, at least I have not met with more than 

 seven or eight, and these were found in Matford lane. H. fusca: two specimens 

 of this species on Exmouth warren are the only ones I have seen. H. aculeata 

 has been found in Stoke wooi, by the Rev. T. Hincks, but I believe that 

 gentleman only found one specimen, which he showed me: I have myself 

 hunted the wood several times, hoping to have met with it, but have each 

 time been disappointed. 



H. hispida is particularly abundant in gardens about Exeter; also H. concinna 

 and H. depilata: (to me a doubtful species.) I have had H. rufescens from 

 Torquay, but have not met with it here. H. virgata is very numerous indeed 

 on the short grass, near the old lime-kilns at Counties Weir. This species 

 varies considerably in its markings, as it does also in size, for I have met with 

 specimens on Teignmouth den, half as large again as those found further 

 from the sea, and here they have a greater abundance of food than those 

 found near the beach. What can make the difference in this larger development 

 of growth and shell, can it be the more equal temperature near the sea, than 

 at the more inland stations? H. caperata: this is frequently to be met with, 

 very often in company with H. virgata. In the more inland stations Zonites 

 rotundatus is very common everywhere. Z. alliarius: many specimens I have 

 met with in Stoke wood, all of which have given out a very offensive smell 

 of garlic. Z. cellarius very common and very fine. Z. lucidus: I have only 

 met with two specimens of this; they were found in a wet meadow near the 

 Exe. 



Succinea putris: this shell does not appear to be very common, though I 

 have found some very fine specimens by the side of the canal. S. Pfeifferi: 

 this is common by the side of the canal and ditches in Exminster marshes. 

 S. oblonga: I, last year, found three or four specimens of this shell in the
