GASTEROPODA.

application of the same name, too, by British and continental authors, to 
different species, adds much to the confusion. Ireland possesses all the 
British species as distinguished by Mr. Alder, viz. H. cellario , H. nitidula , 
H. lucida, H. excavata , H. alliaria , IL radiatula , H. pura, H. crystallina. 
Rossmassler’s H. nitens, f. 524 and 525, are very characteristic represent- 
ations of shells I possess from different parts of Ireland, and with his H. 
glabra , f. 528, so far as a figure and diagnostic description will suffice for 
judgment, I have specimens identical. 
Genus Succinea. 
S. putris, Flem., 
Is generally distributed throughout Ireland. Specimens agreeing with 
the var. /3 of Draparnaud — “ major solidior, colore carneo” — in form (see 
pi. 3, f. 23), colour, and more than ordinary thickness, though not in 
being larger than, usual, are occasionally met with. The varieties y (“ me- 
dia magis elongata et colorata ”) and d (“ minor, apertura ovata ”) are 
found in the North. Individuals of this species, which adhere to stones 
in wet spots at a considerable elevation in the northern mountains, are, as 
may be expected, invariably much dwarfed in size. 
S. Pfeifferi, Rossm. 
Although less common than the last, this species or variety is widely 
diffused over the island. In the North it is not uncommon, and is here 
generally of the same amber colour as S. amphibia ; as likewise are Eng- 
lish specimens, which I owe to the kindness of Mr. Alder ; specimens 
of a reddish horn-colour, and much thicker than usual, have occasionally 
occurred to me in the North, and in quantity they have been obtained by 
Mrs. Patterson, of Belfast, near Portarlington. Mr. Humphreys notices 
this shell under the name of S. oblonga, Turt., as found about Cork, and 
by this appellation Dr. Harvey mentions Ballitore (County Kildare) and 
Limerick as habitats, adding at the same time — ■“ animal darker than in 
the last [& amphibia ], and found in far wetter places.” From Finnoe 
(County Tipperary) I have been favoured by Mr. E. Waller with typical 
specimens of this Succinea, as admirably represented in Gray’s Manual 
(f. 74). 
S. oblonga, Drap. 
Bishop’s Crook, Cork, Messrs. Wright and Carroll. Baltimore, Co. Cork, 
Mr. M‘Andrew. 
Genus Bulimus. 
B. obscurus, Drap. 
This species is very local. In his Irish Testacea Capt. Brown notices 
“ one specimen [procured] on a dry mud wall near Clonooney,” p. 529. 
About the roots of trees in the demesne of Woodlands, near Dublin, I 
have, accompanied by Dr. R. Ball, obtained specimens, the shells of 
all of which, adult as well as immature, were like those sent me from 
other localities, and, according to the observations of authors, covered 
with earth. From La Bergerie, Portarlington, I have been favoured with 
specimens by the Rev. B. J. Clarke. In March, 1837, it was supplied me 
in quantity from Larne, County Antrim, by Mr. James Manks. From 
the Falls of Clyde (Scotland), I have specimens collected by Dr. W. 
H. Harvey.
