All the ponds from whicli shells have been collected are connected 

 with streams which run into them, and after a more or less short 

 course flow into the sea. With regard to the streams at Borough, 

 both that running from the pond, and the distinct one at some little 

 distance off, join a larger stream which falls into the sea at Lee. It 

 may be noted that P. personatum occurs both in the pond and in 

 the stream at Borough, whereas F. casertanum has only been found 

 in the stream. The stream which runs into the sea near Bennetts- 

 Mouth flows from Damage Pond, and P. casertamun occurs in both. 

 The small stream in Church Close, where P. personahwi is the only 

 form hitherto taken, rises in the field above and has a very short 

 course of about one mile to the sea. 



It is somewhat remarkable that I have not met with a single species 

 of Planorbis in the district, though they occur in the ditches at Braun- 

 ton Burrows about six miles off. 



Inland the most abundant species are Helix ?iemoralis, H. aspersa, 

 Vitrea ce/laiia, and Arion ater ; near the sea, ff. virgata on the sand 

 dunes and walls ; H. aspersa also occurs on the latter. 



It has been thought advisable to include in the list several of the 

 rarer species taken at Croyde, Braunton, and Tlfracombe, some of 

 which have not been found in the parish. These are all placed in 

 square brackets, as well as the notices of species found by other 

 persons. The rocks at Croyde and Braunton being of more or less 

 similar structure, though of later age, do not render that part more 

 favourable for land shells, but the numerous nearly stagnant ditches 

 harbour many aquatic species. Limestone (Devonian), however, 

 occurs at Ilfracombe, which makes that neighbourhood much richer 

 in land mollusca. As these have been so ably worked out by Messrs. 

 Tomlin, Beeston, and Wright, very little reference has been made to 

 recent finds there. I may state, however, that I found, as they noted, 

 Pyramidula rotundata var. alba very abundant at Hele in July, 1908, 

 but I only met with two dead specimens of Vitrea hicida Drap. in 

 Rapparee Lane. 



The number of species found is fifty-seven ; of varieties, thirty- 

 two. Of these, twelve species and one variety were only taken outside 

 the strict limits of the parish. 



The nomenclature adopted is that of the List of British Non- 

 Marine Mollusca, prepared by B. B. Woodward, and published by 

 the Conchological Society, 1904; with the exception of the genera 

 described by J. W. Taylor in his Monograph of the La7id and Fresh- 

 water Mollusca of the British Isles, 1908. 



I must acknowledge my indebtedness to Mr, B. B. Woodward for 

 kindly naming the Pisidia ; also ■ to Mr. Taylor, Mr. W. Denison 

 Roebuck, and Mr, F. Partridge for similar help with other specimens.
