The Irish Naturalist. 



February 



Hyallnia radiatula ( Alder). — -(X.) — Generally distributed, to 1,400 feet on 

 Connor Hill, but not so common as the last species. Sparingly at one 

 spot on the Gt. Blasket. 



H. crystallina (Miiller). — (T.) — -On the Gt. Blasket and almost everj'whcre 

 on the mainland, to 2,300 feet on Brandon Mountain. At Glenfahan, 

 on Slea Head, this shell was very common in " moss -shakings," and 

 two forms of it are noticeable. One is greenish, with very deep whorls 

 and minute umbilicus ; the second is more white in colour, has flatter 

 whorls, and a slightly wider umbilicus. 



Zonitoides nitidus (Miiller). — (T.)— Recorded from Mr. Tomhn from a 

 marsh near Cloghane, and taken by me in the marshes at Gallerus 

 and Stradbally. In the latter locality it appears to be common. 



Z. excavatus (Bean). — This species was only discovered on the promontory 

 on my last visit, and though common in parts of the woods at Burnham 

 and at Kilcummin, it is extremely local. All the specimens taken at 

 Burnham were of the type, while, on the contrary, all seen at Kilcummin 

 belonged to the greenish form. A single specimen of the type occurred, 

 also in the gorge of the Finglass River. At Kilcummin this shell was 

 one of the three commonest in the woods, the other two dominant 

 species being Pyraniidula rohmdata and Pupa anglica. It is, therefore, 

 more than strange that it is not more widel}^ distributed in the district. 



Euconulus fulvus (Miiller). — (T.) — Recorded by Mr. Tomlin as common near 

 Cloghane ; but though frequent throughout the district, to 1,300 feet 

 on Connor Hill, and on the Gt. Blasket, it never occurred to me plenti- 

 fully. 



Arion ater (L.) — (T.) — Mr. Tomlin records the vars. castanea, aterrima, and 

 bi color from the neighbourhood of Cloghane. Var. aterrima appears 

 to be confined to the mountains, and near the coast is replaced by 

 the type and the vars. castanea and plumbea. This slug was abundant 

 on the Gt. Blasket, occurred sparingly on Beginish, and on the main- 

 land is ubiquitous even to the summit of Brandon Mountain, 3,127 

 feet. 



A. subfuscus (Drap.). — (T.) — Recorded by Mr. Tomlin as common at 

 Cloghane ; but appeared to me to be much rarer than in the north of 

 Ireland, and was distinctly local in its distribution. It occurred to 

 me at Glenfahan, at Slea Head ; at 900-1,200 feet on the cliffs at 

 Brandon Head ; in several places near Dingle ; in Fermoylo and 

 Kilcummin woods ; at Stradbally and Cloghane ; and to 2,800 feet 

 on Brandon Mountain, as well as on both the Blaskets visited. 



A. intermedius Normand. — Generally distributed on the Blaskets 

 and in the valleys on the mainland, and occurs to at least 2,800 feet on 

 Brandon Mountain. The specimens taken in the last mentioned 

 habitat were of a golden yellow colour with a brilliant orange footsole. 



[A. hortensis Fer. — Only seen in the plantations at Burnham and by the 

 Finglass River, near Camp. Unfortunately no specimens could be 

 found outside these two places. Here introduced plants are to be 

 found also ; and I, therefore, regard the species as of doubtful standing 

 in the district, and possibly introduced. This idea is strengthened 

 by the fact that it w*s not taken in Kilcummin woods, which contain 

 a much larger percentage of native trees than the two habitats 

 mentioned above.]
