A LIST OF THE LAND AND FRESH-WATER SHELLS 

 FOUND IN THE NEIGHBOURHOOD OF EXETER. 



BY Mil. EDWARD PARFITT, 



AccoRDiisro to the promise I made ia my first communication to ''The 

 Naturalist," I now give a list of the Molluscous Animals inhabiting our rivers 

 and ditches, as well as the land and woods of this neighbourhood; at the 

 same time, I beg to state that I am sure more will or may be added to 

 the list. If some one living in Exeter, or in this part of the county, 

 would take upon himself to explore the ditches in Exminster marshes, which 

 laying in near proximity to the sea, I think it possible that our list would 

 be much increased by their researches. I am myself so confined by my occupation, 

 that I have not the time to devote to the several branches of Natural History, 

 which my will and mind grasp atj consequently I must be content with 

 what can amuse and instruct me in my own immediate neighbourhood, with 

 now and then a dart into the surrounding country, something like the points 

 of the angles of a star, shooting out from a common centre. Having said 

 thus much, I will proceed to give the aforesaid list of the Land and Fresh- 

 water Shells. Some time or other I may say a word or two on the Marine 

 Shells and Zoophj'tes, which I have taken, or have been cast ashore on Exmouth 

 Warren, during my peregrinations to that immense bank of sand. 



First then is Paludma acliatma: this is very common indeed in the Exe; 

 they are sometimes brought down the river in times of flood, or at least 

 very high water, and deposited at what is called the Lower Weir, by the 

 Salmon pool, so that many barrows (I had almost said cart-loads) might be 

 taken away were they of any particular use. Bithinia tentaculata: this is also 

 particularly common in low meadows and stagnant waters. Valvata piscinalis: 

 this is not common; I have only met with two or three. Arion ater: this 

 species is not particularly common, at least I have not seen more than three 

 or four. I met with a very beautiful variety, of what I suppose A. hortensis, 

 last autumn, on the Topsham road, not far from Exeter; it was of a bright 

 orange-red colour, with a broad, irregular, longitudinal streak, reaching from 

 the anterior part of the mantle to very near the tail, of a beautiful bright 

 umber colour: this colour contrasts so greatly with the bright orange red of 

 the rest of the body, that it gives the slug a very beautiful appearance. I have 

 seen two of these, and both precisely alike, but I unfortunately did not preserve 

 them; but the next that crosses my path, will very probably find its way 

 into a bottle of Goadby's fluid. 



Limax maximus is very common in gardens, outhouses, etc. L. slavus 

 is not so abundant as the former, but several of these are to be met with 

 very frequently where they are not wanted. L. carinatus: this species is frequent 

 about here, in gardens. L. agrestis is much too common. Vitrina pellucida 

 is rather abundant in pleasure grounds, in damp places amongst leaves; and 

 I have to record the finding of Testacella haliotoides in this neighbourhood;
