Freshwater Mollusca of Ireland, 111 



Zua lubrica, Gray, Man. p. 188. pi. 6. f. 65. 



Helix lubrica, Mull. Mont. p. 390. t. 22. fig. not good. 



Is common, and generally distributed over Ireland. From under 

 stones on the dry mountain side at Wolfhill, near Belfast, and on 

 sea-side pastures I have obtained a few specimens of a handsome va- 

 riety, 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 differ- 

 ent places in the north of Ireland, from the month of December to 

 March, during a mild winter, it would appear either that the B. lu- 

 bricus 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. 



7. Achatina, Lam. 



1. A. Acicula, Lam. Gray, Man. p. 191. pi. 6. f. 71 ; Turt. Man. p. 

 89. f. 71. 

 Bulimus Acicula, Drop. p. 75. pi. 4. f. 25, 26. 

 Buccinum terrestre, Mont. p. 248. t. 8. f. 3. 



This handsome species is found sparingly, but from east to west, 

 in the more southern half of Ireland. Mr. W. H. Harvey has pro- 

 cured it on the " sand-hills, Miltown Malbay, and from under stones 

 near Limerick/' but in the latter locality marks it as " very rare." 

 Mr. T. W. Warren of Dublin, has supplied me with specimens pro- 

 cured by him on different 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 Water- 

 ford). 



For the Cionella elongata, Jeff, noticed with doubt as Irish by Mr. 

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

 under Achatina octona. 



8. Pupa, Lam. 



1. P. umbilicata, Drap. p. 62. pi. 3. f. 39, 40 ; Gray, Man. p. 193. 

 pi. 7. f. 78; Turt. Man. p. 97. f. 78. 

 Turbo muscorum, Mont. p. 335. t. 22. f. 3. 



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 eleva- 

 tion in the mountains it is foundt. It is subject to considerable va- 



f Mr. Alder, with reference to Newcastle-upon-Tyne, remarks of this spe- 

 cies — " under stones, common ; seldom in moss" (Newc. Trans, vol. i. p.33); 

 in Ireland it is common among mosses and lichens in suitable localities.
