290 MOLLUSCA. 



few specimens, noting the species at the same time as " very rare." Mr. 

 T. W. Wan-en of Dublin informs me that early last winter he procured 

 sixty individuals of this species on one occasion near Portmarnock 

 (County Dublin) : some weeks previous to this time he found a few spe- 

 cimens at the place, and following the plan of the Rev. B. J. Clarke, 

 he laid down sticks and stones that they might shelter under them, 

 and Avith such success that he obtained this number. None of our 

 Mollusca more than this requires the collector to be wide awake, else 

 he may pass it by for a pellet of dirt, or at least a seed. As one of the 

 rarer species, it may be mentioned that out of Ireland I have found this 

 shell at Dovedale, Derbyshire, the " dean " at Twizel House, Northum- 

 berland, and near Ballantrae in AjTshire. 



H. lamellata, Jeffreys. 



This attractive species is widely distributed in Ireland, and is found on 

 the decaying leaves and fallen branches of trees, in moss, and under stones 

 in shady and generally moist situations. I fii'st met with it in Sept., 

 1833, in the Glen at Holywood House, County Doaati, and soon after- 

 wards in various localities throughout this County and Antrim ; about 

 O'SulHvan's cascade, at the lower lake of Killarney, I had the gratifica- 

 tion to find it in June, 1834, and subsequently in the Glen of the Downs, 

 County Wicklow. By the Rev. B. J. Clarke it has been obtained at La 

 Bergerie, Queen's County, and by the Rev. T. Hincks of Cork at Duns- 

 combe Wood near that city, and likewise at Ballinhassig Glen, between 

 Cork and Bandon. Mr. Hincks remarks that the species appears to be 

 far from uncommon in that district. 



The following note relates to my most successful capture : April 30, 

 1837. — In Colin Glen (near Belfast), during an hour's patient search to- 

 day, I collected from amongst a mass of the dead leaves of trees contain- 

 ed within the area of a square foot twenty-one full-grown individuals of 

 Helix lamellata, and about half this number of younger specimens ; both 

 shell and animals of these latter are lighter coloured than the old, indeed 

 almost hyaline, and the lamelte are apparent on the very youngest, which 

 also exhibit the satin-like lustre of the adult. The mature animal is 

 white beneath ; the tentacula, back, and sides greyish black ; lower tenta- 

 cula of moderate length, upper long and somewhat club-shaped. 



In Auchairne Glen, near Ballantrae, Ayrshire, I obtained this species in 

 August, 1839.

This would seem to be a very local species with us. By Dr. W. H. 

 Harvey I was in 1834 supplied Avith specimens, accompanied by a note, 

 stating that the species had occurred to him in " moist places, and the 

 rejectamenta of streams about Limerick and Ballitore (County Kildare)." 

 At the same time Mr. Humphreys, of Cork, reported it to me as found, 

 but not commonly, at " Belgrove demesne, east of Cove." 



H. hisptda, Mull. 



This species is generally distributed over Ireland. It is one of the most 

 common land shells in the North, and may be found under stones, fallen 

 trees, decaying leaves, &c., from the sea-shore to the most elevated chalk 

 districts, and both in moist and very dry situations. It is most variable
