1904. Welch & Stelfox. — Sligo Co7iference, Molhisca. 189 



mountain above GlenifF, altitude i ,700 feet, Stelfox and Gunn found 

 a colony of large heavy shells, var. rubella, with white lip^, and var. 

 roseolabiata ; unfortunately, they were much weathered— some had 

 hardly any epidermis remaining. Some of these measure 24 x 19 

 and 23 X 20 mm. They were also fairly common and large in the 

 cave mouths, GlenifF. All over the dr)- stone walls of the beehive 

 cells, sweat-house, and cashel, Inishmurry, sestivating in the 

 crevices, we found a large race of this species in 1900, more like the 

 Valencia Island shells than the still larger Aran form. 



H. aspersa, Mull. — Not common anywhere except about Doonfore, 

 Knocklane, and one little stone heap on margin of the sandhills near 

 the old castle, Raghly. We have never found before in any part of 

 Ireland so much variety in colour, markings, size, and shape, as occurs 

 on this limited area; almost all the texture, shape and colour 

 varieties (so called) were there with connecting forms also. A dozen 

 dead shells broken in a mouse run, Strandhill ; a few at Rosses Point, 

 rare at Rockwood and Glencar. At latter place Mrs. Praeger found a 

 very beautiful large specimen of the var. tuididata, Moq. In the 

 cashel on Inishmurrj', and at Dromahaire, 1900. 



SiNiSTRAi, FORM. — While the forms living with H. nemoralis at 

 the Knocklane end of the dunes were mainly light banded, at the 

 Raghly end A. W. Stelfox found a little stone heap about ten yards 

 long, where dark bandless forms, exceedingly rare in Ireland, were 

 plentiful ; some were almost black, but most had unfortunately lost 

 the greater part of the epidermis. Some were unicolorous, 

 {nigrescent Moq. .-') others with a little banding or narrow undulatory 

 markings, and some very thin. While we were examining these he 

 was fortunate enough to find a fine dark reversed specimen alive. 

 It was about three quarters grown, and is the first we have any 

 knowledge of in Ireland. A few have been recorded {/ourn. of 

 Conch.) from various parts of England. Needless to say it is, like Mr. 

 Standen's specimen {/oum. of Conch., vi., p. 176) being pampered, 

 and is making shell fast. It does not seem to be as active as dextral 

 specimens we have kept alive for over nine years past, and likes to 

 shelter under the lettuce it is fed on during the da}'. Mr. Standen, 

 whom we missed very much at this Conference, gives {loc. cit., vii., 

 PP- 33-38) a most interesting account of the reproduction of lost 

 love-darts in his sinistral and a dextral specimen vShould we 

 succeed in rearing it to maturity it will be carefully dissected to see 

 if the organs differ in position, &c., from those of dextral specimens. 

 (See Plate 9). 



Buliminus obscurus, Mull.— This species seems to have mainly 

 an eastern and northern range in Ireland (see Scharff, I.N.. 1892, p. 

 109). It is common but very local near Larne and Belfast. We found 

 it near Athlone on our way home from the Galway Conference, 1895. 

 A keen search in many likely habitats in woods and at base of cliffs 

 gave no results about Sligo, and we were much surprised to find 

 14 dead specimens all close together (a dinner plate would have
