200 STANDEN : MOLLUSCA OF PORTSALON. 



H. aspersa Miiller. — Very common and full-sized everywhere 

 on old walls and bare slopes facing the sea. Those sheltered 

 by walls are richly but uniformly marked, whilst those ex- 

 posed in the open are quite destitute of epidermis, and look 

 dead and weathered, but were quite lively and pairing 

 freely. It extends quite down to the sea-shore, indeed I 

 found numbers feeding on a heap of decaying sea-weeds 

 piled up at the foot of a cliff. I also noticed many shells 

 on the sands, still damp from the outgoing tide, which had 

 evidently been blown off an overhanging cliff during the 

 night, and it was interesting to observe the unerring instinct 

 with which each animal was making all speed for the base 

 of the cliff, which many had already reached and were scal- 

 ing, their tracks in the sand plainly showing the distance 

 travelled. 



*Cochlicopa lubrica JNIiiller. — Common everywhere together 

 with its varieties ovata, liibricoides, and liyalina. 

 Pupa anglica Fer. — Several nice white-lipped specimens in 



the golf-links rejectamenta, Portsalon. 

 P. cylindracea DaCosta. — Generally distributed, but re- 

 quired careful search, and I only found it singly here and 

 there, chiefly under the uppermost stones of old moss- 

 covered walls. Two forms occur, one unusually long, the 

 other short and stumpy. 



*P. muscorum L. — Fairly plentiful in rejectamenta (dead), 

 and alive under stones on the shore just above high-water 

 mark at Portsalon ; very large living specimens under stones 

 at Kinny Lough. Several pure-white translucent fresh 

 shells (var. albina Menke) from the Portsalon rejectamenta. 



*Vertigo antivertigo Drap. — Not uncommon in the golf- 

 links rejectamenta, Portsalon. Very fresh and beautiful 

 specimens. 



*V. edentula Drap. — Pretty common on dead bramble 

 twigs, and the moss-covered stones below them, on road- 

 side near Portsalon. The specimens on the brambles were
