1915. Stelpox. — Molliuca of Diuoie Promontory. 31 



was taken in quantity. Besides the above stations it was found at 

 Smerwick Bay, on the cliffs of Carrigblagher, on the Gt. Blasket, and 

 near Cloghane (Tomlin). Tlie specimens collected on the great sea- 

 cliffs of Knocknabreestee appear to be of a depauperate form, and 

 bear the same relation to the type that the var. anconostoma bears to 

 typical Pupa cylindracea. In these dwarf examples only four denticles 

 appear in the aperture of the shells, instead of the usual six. One 

 denticle is situated on the body -whorl, one on the columella, and 

 two on the outer lip ; occasionally there is a trace of a second denticle 

 on the body -whorl, 



V. pygmaea (Drap.), — (T.) — Generally distributed at low elevations, but 

 was not seen on the Gt, Blasket nor in several stations where V. 

 substriata occurred. In all the marshy areas it was abundant, asso- 

 ciated with V. antivertigo. In the neighbourhood of Dingle and 

 Cloghane it was frequently common on the tops of dry ditches and 

 in similar places. By the roadside on Slea Head many specimens 

 were taken also, and it was found associated with the last species 

 on the cliffs of Carrigblagher, In the last habitat it was proved to 

 live to nearly 700 feet alt., its highest recorded station in the district. 



V. angustior Jeffreys. — (T.) — The abundance of this Vertigo in the earlier 

 Holocene deposits of Ireland and England, compared with its extreme 

 rarity in the living state, is a fact which will always lead to speculation 

 regarding the causes which have led up to its present scarcity. Mr. 

 Tomlin reports this species as " extremely local, but not uncommon 

 under stones on the bank of a small stream, close to where it entered 

 the sea." One specimen was taken by me under a stone on the dunes 

 opposite Fermoyle House, which cannot be far from the habitat 

 mentioned by Mr. Tomlin ; and three specimens were taken by me 

 from a similar position on the dunes at Ferriter's Cove. No doubt 

 further search would have revealed additional specimens ; but in 

 both instances I felt satisfied with proving that in this, as in other 

 western districts, the species was not yet extinct. All my specimens 

 are darker in colour than any I have seen previously ; they are as 

 dark, in fact, as normal V. pygmaea. 



Balea perversa (L,). — (T,) — At Burnham and several other places near 

 Dingle ; in the gorge of the Finglass River ; on walls at Castlegregory ; 

 Gallerus ; and on the ruins of the old church at Stradbally, Mr. 

 Tomlin reports having beaten many specimens from Gorse bushes 

 in the Cloghane district, and remarks upon the frequency of its 

 association with this plant. 



Clausilia bidentata (Strom). — (T.) — On the Gt. Blasket and Beginish, and 

 generally distributed on the mainland to at least 1,200 feet, at which 

 height it is abundant on the roadside wall by the road from Cloghane 

 to Connor Pass. On the tombs in the graveyard at Stradbally this 

 shell was more abundant than I have ever seen it elsewhere. 



Succinea Pfeifferi Rossm. — (T.) — In the marshes at Stradbally, Inch, 

 Ventry, and Smerwick Bays ; and also by the shore of Lough Anscaul. 

 Reported by Mr, Tomlin from marshy ground near the shore in the 

 Cloghane district. All my specimens belong to the small obese form
