l68 Rev. R. Sheppard's Account 



It is the Limneus ovatus of Draparnaud, who erroneously iden- 

 tifies it with the H. limosa of Linnaeus. 



Q5. Helix limosa. Linn. Syst. Nat. ed. xii. vol. ii. p. 1249- 



Helix putris. Trans. Linn. Soc. vol. viii. p. 219. 



In abundance in most rivers, marsh ditches, and ponds. 



Draparnaud has made two species of it, viz. Litnneus peregra 

 and L. ovatus. It is the H. peregra of Montagu, and H. putris 

 of Dr. Maton and Mr. Rackett ; so that it would appear that the 

 H. limosa of Linnaeus was unknown to modern Conchologists. 



But surely there is no occasion for the trivial names succinea 

 and peregra ; — with me, at least, there is the strongest convic- 

 tion, that as H. succinea of Dr. Maton and Mr. Rackett is the 

 H. putris of Linnaeus ; so also is the //. putris of those authors 

 and the H. peregra of Montagu the true H. limosa. 



It must be observed that this species is frequently found with 

 five volutions, in which state Linnaeus described it. I have spe- 

 cimens from Mrs. Cox's pond in Wrabness, which equal one inch 

 two lines and a half in length ; and a curious variety from the 

 pond below Ramsey Decoy, in which the margin is so extremely 

 dilated as to give the lowest volution the appearance of a hunts- 

 man's cap.

In Campsey Mere and Holbrook stream ; and at Baylham, 

 below the Fall in the Back-water of the River Gipping belong- 

 ing to Sir William Middleton, Bart. 



I have a dwarf variety from the pond in Fearis' wood in Beau- 

 mont, Essex. Also two fine varieties from the stream between 

 Langford Fleet and the River Trent, Notts, — in one of which the 

 inside is purplish ; in the other, of a delicate silvery white, and 

 the margin is considerably dilated.
