298 MOLLUSCA. 



viewed under a lens appearing closely marked all over the back and 

 sides Avith 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. actifus, " Brug." 

 This is a local s])ecies, 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 Avould 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. articulatiis, Lam. 



jB. luhricus, " Brug.," 



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 stai'lings 

 {Stnrnus 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 

 thu'teen in number. 



Genus Achatina. 

 A. Acicida. 



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 Rev. 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).

 freys, Linn. Trans, vol. xvi. p. 348, see Gray's Manual, p. 18, under 

 Achatina octona. 



Genus Pupa. 

 P. umhilicata, Drap. 



. This is one of the most common of the testaceous Mollusca throughout 

 Ireland and her islands, and especially abundant Avhere limestone and 

 chalk prevail. From the sea-shore to a great elevation in the mountains
