Itis the Limneus ovatus of Draparnaud, who erroneously iden- 
tifies it with the H. limosa of Linnæus.

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. Limneus peregra 
and L. ovatus. Itis the H. peregra of Montagu, and H. putris 
of Dr. Maton and Mr. Rackett ; so that it would appear that the 
H. limosa of Linnzus 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- 
ton, that as H. succinea of Dr. Maton and Mr. Rackett is the 
H. putris of Linnzus ; so also is the H. 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 Linnæus 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. x

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 havea 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.
