-I So The Irish Naticralist. [July, 



Rathlin Island. 



Vltrlna pelluclda, Mliller.— One very fine but "dead" shell was 

 found at Church Bay. NO-doubt, in suitable damp mild winter 

 weather it will prove common. 

 Hyallnla cellaria, MuUer. — This species was found to be common at 



Church Bay. 

 Hyallnla DraparnaudI, Beck.— A few specimens were found with 



the last species. 

 Hyalinia alllaria, Muller.— Both the type and the variety viridula 



were found, chiefly at Ushet Point. R. Welch also took it in 1889. 

 Hyalinia pura, Alder. — One specimen of the brown form was found 



at Ushet. 

 Hyallnla contracta, West. — Three or four of this form occurred 



near Ushet Lough. 

 Arlon ate I*, L.— Both the type and the var. brimnea (Roeb.) were 



plentiful. 

 Arion subf uscus, Drap. — Though the typical form was not observed, 

 the beautiful brilliant orange v. anrantiaca (Loc.) was very abundant. 

 Arlon hortensls, Fer.— One or two specimens at Church Bay. 

 Arlon Intcrmedlus, Normand. — Moderately common. 

 Llmax maxlmus, L. — The var. Finissaci (Moq.) was very common, 

 though the typical form did not occur. The prevalence of this 

 handsome form to the exclusion of the type is also noticeable on 

 the mainland opposite. Indeed, the true type only occurred once, 

 at Murlough, the varietal form being exceedingly common. 

 Llmax f lavus» L.— A flourishing colony of this handsome species was 

 discovered in the little wood at Church Bay, most of the individuals 

 being of the form siiffusa (Roeb.) 

 Llmax marginatus, Muller. — (= Z. arbomm Br. Ch.) This slug is 

 extremely common on the island. Many were of the pale colour 

 usual in N. Ireland, but the handsome var. Bettonii (Sord.) was equally 

 common. 

 Agrlollmax agrcstls, L- — Was extremely common, as also the purple- 

 coloured var. sylvatica (Moq.) 

 Amalla Sowcrbyl, Fer.— Common. 

 Amalla g^agates, Drap.— Two specimens of the dark-backed type 



were obtained at Ushet. 

 Helix rotundata, Muller.— Common and diffused. (Welch in 1S89). 

 Helix pulchella, Mullen— Two specimens of the type were found at 



Ushet. 



Helix hisplda, Linn.— Very common and diffused. Two specimens 

 of the var. albida (Jeff.) were obtained at Church Bay. 



Helix vlrgata, Da Costa.— A colony of the nondescript form known 

 as sub-mariiima was found along the shore of Church Bay— no types 

 being found ; and as far as my experience goes this is the case all 

 along the N. coast of I ' Ister. Welch took it in 1889.
