STANDEN : MOLLUSCA OF PORRSALON. I97 



*H. nitidula Drap. — Under stones on road-sides, Portsalon, 

 and in the burial-ground, Fahan. I took along with the 

 type three very pretty specimens of the pearl-white variety, 

 Helmii Alder, alive. 



*H. pura Alder. — Not uncommon about Portsalon, and princi- 

 pally the whitish form (type), but the brown variety also 

 occurs sparingly. 



H. radlatula Alder. — A few under moss-covered stones in 

 company with Vertigo edentida on road-side near Portsalon. 

 All taken were of the greenish-white variety viridescenti-alba 

 Jeff. 

 *H. crystallina Miiller. — Not uncommon at Portsalon. A 

 small compact form which may prove to be the variety 

 contractu Westerlund. 



*H, fulva Miiller. — Under stones at Portsalon, and on road to 

 the Seven Arches ; on moss-covered logs at Kinny Lough, 

 and dead amongst the golf-links rejectamenta. 



Arion ater L. — Very abundant, together with var. brunnea 

 Rbk., especially at Portsalon, where I counted over forty 

 specimens on one rubbish-heap near the hotel. I had a 

 curious experience with a large specimen which I picked 

 up at the Seven Arches, and carried in my hand for a long 

 time, enclosed in a dock leaf. A rasping sensation in the 

 palm of my hand revealed the fact that the Arion's jaws 

 were at work on my cuticle, and I allowed it to gnaw away 

 until it was so near through that the operation became too 

 painful to bear. Examination of the spot with the lens 

 showed the skin almost rasped away, and the place re- 

 mained tender and sore, like a slight burn, for several days. 



A. subfuscus Drap. — Several specimens at Portsalon and 

 Kinny Lough. 



A. hortensis Fer. — Not uncommon in a wood at Portsalon, 

 and in the burial-ground at Fahan.
