1897.] Adams. — LaJid a7id Freshwater Mollusca of Ballycastle, 181 



Helix erlcetorum, Miiller.— The typical form and also var. instabilu 

 (Zeigl.) and var. minor (Moq.) occurred on each side of Church Bay, 

 but not with H. virgata. These two species are said never to live 

 together in Ireland, though this is certainly far from the case in 

 England. 



Helix acuta, Miiller.— In Church Bay with H. virgata. 



Helix nemorallS) Miiller. — As on the mainland opposite, the white- 

 lipped variety was not uncommon. The following are the forms 

 met with : — 

 The Type. 



V. libelhda (Risso) ooooo, (i 2 3) 4 5, (i 2 3 4 5). 

 V. libellula (Risso) and albolabiata (v. Mart.) ooooo. Common. 

 V. rubella (Moq.) ooooo, 00300. 



Helix aspersa, Miiller. — The rather dark form common in North 

 Ireland was very plentiful, and two specimens of var. tennior (Shuttl.) 

 were obtained. 



Cochllcopa lubrlca, Miiller. — Several specimens were taken which, 



when cleaned, presented more of a greenish tint than usual. (Welch 

 in 1889). 



Pupa cyllndracea. Da Costa. — Some found near Ushet I,ough. 



Clausula bldentata, Strom.— This was found abundantly round the 



church and neighbouring wood. 

 Succlnea putrls, L. — Many small specimens were found in a small 



stream flowing into Ushet I^ough opposite the crannoge. 

 Carychlum minimum, Miiller.— One or two were obtained near 



Ushet Point. 

 Llmnaea peregra, Miiller Several small specimens were found in a 



small weedy pond near Ushet Lough. 

 Llmnaea truncatula, Miiller. — In the little stream mentioned above, 



some small specimens were found. 

 Physa fontlnalls. L.— A single small specimen in Ushet Lough by 



the crannoge. 

 Ancylus f luvlatllls, MuUer.— The same little stream furnished many 



specimens; and also another little stream by the church-yard at 



Church Bay. 

 Pisldlum puslllum, Gmel.— In the stream flowing into Ushet Lough 

 among some dwarf Water-cress a few small typical specimens were 

 found ; also a few in the Lough itself 



Mainland. 

 With regard to the mainland the following notes are in- 

 tended as a supplement to Mr. Standen's previous list, not as 



a new independent list : — 



Hyallnla Draparnaudl, Beck.— Immature specimens were exceed- 

 ingly plentiful at Murlough, though, as Mr. Standen found in 

 September, adult specimens were not common— in fact our search 

 only resulted in a few dead adults, though mature specimens ought
