MOLLUSCA. 
viewed under a lens appearing closely marked all over the back and 
sides with darker spots and markings so disposed as to render it very 
beautiful ; disk very pale grey. Tentacula cylindrical, stout, and club- 
shaped ; the upper of ordinary length, the lower short. 
B. acutus, “ Brag.” 
This is a local species, but found from North to South — from the neigh- 
bourhood of the Giant’s Causeway to Youghal. It is especially common 
on sea-side sand-banks and pastures, but in remote inland localities is 
likewise native. It would seem to be more common to the eastern than 
the western portion of the island, but in the latter it has occurred to me 
about Ballyshannon, County of Donegal, also at Dunfanaghy, Larne, 
and Springvale, Co. Down. I have occasionally observed this species in- 
habiting the crevices of walls at a considerable height, as those of Howth 
church, County Dublin. M. Michaud remarked on some Irish specimens 
of this most variable species which I contributed to his collection, that 
they were the B. articulatus, Lam. 
JB. lubricus, “ Brag.,” 
Is common, and generally distributed over Ireland. From under stones 
on the dry mountain-side at Wolfhill, near Belfast, and on sea-side pas- 
tures I have obtained a few specimens of a handsome variety, of a pale 
grey colour, and transparent, with a white peristome ; in such localities 
this shell does not present to the same degree the rich amber colour and 
brilliant polish which it does in woods or shady places. The animal is 
blackish. From an examination of the food contained in seven starlings 
( Sturnus vulgaris), shot at different places in the North of Ireland, from 
the month of December to March, during a mild winter, it would appear 
either that the B. lubricus is a special favourite, or that its haunts are 
similar to those of the bird ; as six of the starlings, in addition to Helices 
and other food, contained specimens of this shell varying from five to 
thirteen in number. 
Genus Achatina. 
A. Acicula. 
This handsome species is found sparingly, but from East to West, in 
the more southern half of Ireland. Dr. W. H. Harvey has procured it 
on the “ sand-hills, Miltown Malbay, and from under stones near Lime- 
rick,” but in the latter locality marks it as “ very rare.” Mr. T. W. War- 
ren of Dublin has supplied me with specimens procured by him on differ- 
ent occasions in the rejectamenta of the river Dodder, near that city. At 
La Bergerie (Queen’s County) it is found by the Bev. B. J. Clarke ; and 
at Finnoe (County Tipperary), by Mr. Edw. Waller; by Miss Ball at 
Castle-martyr demesne (County Cork) ; and by Miss M. Ball at Dromana 
(County Waterford). 
For the Cionella elongata, Jeff., noticed with doubt as Irish by Mr. Jef- 
freys, Linn. Trans, vol. xvi. p. 348, see Gray’s Manual, p. 18, under 
Achatina octona. 
Genus Pupa. 
P. umbilicata, Drap-. 
This is one of the most common of the testaceous Mollusca throughout 
Ireland and her islands, and especially abundant where limestone and 
chalk prevail. From the sea-shore to a great elevation in the mountains
