* the Helix detrita of Gmelin, the Helix acuta of Chemnitz, and the Bulimus Gua- 
dalupensis of Lamarck, to be the same shell. It is a Jand shell, common in 
Guadaloupe, and several other West India islands; consequently Mr. Bryer’s 
authority is very questionable. ‘The specimen said to be found by Dr. Turton 
at Dublin, I also considered foreign, and omitted it in my catalogue of the Irish 
Testacea. If this species does inhabit England, it will be found on terra firma, 
and must have been introduced on plants, either in the egg or young state, as 
was the case with the Bulimus decollatus. Can any of your readers point out its 
locality in a living state ? « 
The shell figured by Mr. Kenyon, is therefore new to me as a British species, 
and different in shape from any I am acquainted with. Will he be so kind as 
to point out its locality ? 
Lymnea ovata. This shell I found of a very large size in ditches at Bury in 
Lancashire, in 1813, and figured it in my [lustrations, Plate XLII. Fig. 10, 11. 
giving the synonymes of Draparnaud. 
Lymnea peregra, I consider as the Helix peregra of Gmelin, the Helix putris 
of Linneus. 
Lymnea limosa. Under this species Dr. Fleming has blended the synonymes 
of Lymnea ovata, and peregra, and the Helix putris of Linneus. 
In 1814, I found a shell near Clonooney Barracks, King’s County, Ireland, 
which I considered as the Limosa of Linneus: it was figured and described in 
the Wernerian Memoirs, Vol. II. p. 531. Plate XXIV. Fig. 11. and in the l- 
lustrations, Plate XLII. Fig. 39, 40. 
I gave specimens of this shell to Dr. Turton, who agreed with me in thinking 
it the Helix limosa of Linneus. I have since seen Gualteri’s figure, referred to 
by Linneus, and it agrees with mine. 
Planorbis nitidus. Mr. Kenyon is quite correct in supposing that Lamarck 
has included two species under one. 
Suecinea amphibia. The Helix putris of Gmelin and Montagu. 
Clausilia ventricosa is not the Turbo biplicatus of Montagu. Mr. Kenyon’s 
figure agrees with the Clausilia ventricosa of Draparnaud and Pfeiffer, and is in 
all probability that shell; and if so, is new as a British species. 
Clausilia solida. Myr. K.’s figure agrees with Montagu’s Turbo labiatus, the 
Clausilia labiata of my Illustrations. Plate XLI. Fig. 15. 
Pupa muscorum. Mr. K. is perfectly correct in stating that at least four spe- 
cies have been confounded by authors under this single name. In the Iilustra- 
tions, I have divided it into five species, viz. 
1. Pupa muscorum, Plate XLI. Fig. 3. Mr. K.’s fig. 7.

Helix sylvatica is the Helix hortensis of Uyertde variety with bands, Plate 
XXXIX. Fig. 15. of the Illustrations, and the Bere nemoralis of Montagu, 
variety with the white lip. 
Helix carthusianella of Mr. K, is the Helix Gibsit of the Illustrations. Plate 
XL. Fig. 49, 50, 51. 
Helix cellaria is the H. nitens of British authors. 
Fieliz sericea. This is a new shell to me as a British species. 
The Fig. a a, is the true H. hispida. 
Natural History of the Throstle.—An interesting fact connected with the ha- 
bits of the throstle, ( Turdus musicus, ) was lately communicated to the Plinian 
Society by Mr. Macgillivray. On the shores of the Hebrides, he had frequently 
‘observed small heaps of shells, belonging to two species, the Turbo litioreus and 
Trochus conuloides, always broken, but without the animal, although many ap- 
peared quite fresh,
