Spharium lacusire in large numbers. The coffin boards in the 

 churchyard at Clare-Galway yielded a great variety of slugs, 

 Arion intermedins and Limax flavtis being in abundance. 



14TH September. — We moved on to Roundstone, working 

 Ballynahinch on the way. Having reached the granite of 

 Connemara and left the limestone area behind, fresh species 

 were not long in turning up. We visited the spot where 

 Dr. Chaster and Mr. J. R. le B. Tomlin in 1902 1 rediscovered 

 Vertigo lilljeborgi on the shore of Ballynahinch Lake. At this 

 spot we took about twenty specimens in all, but near the out- 

 let of the lake, about a mile distant, Dr. Chaster and I took 

 seven specimens, which indicates that the shell will probably 

 turn up in other localities in the district. 



15TH-19TH September were spent at Roundstone. Dog's 

 Bay and Cregduff Lough occupied most of our attention, but 

 a visit was paid to Maumeen Lough and Ballinaboy on the 

 coast road to Clifden. A short time was also spent on Inish- 

 macdara, twenty-three species being recorded, most of which, 

 however, were found there in 1895 by Mr. Welch. 2 At Dog's 

 Bay Vertigo angustior was living in great quantity, and we 

 were all very much elated at finding it alive, as dead shells 

 of this species are more numerous than those of any other 

 Vertigo in the "shell-pockets" of most of our northern and 

 western sand dunes, and yet we have often searched in vain, 

 in neighbouring marshy situations, to find living specimens. 

 This appears to be only the third time this species has been 

 found alive in Ireland. Miss Warren has taken it sparingly at 

 Bailina, in County Sligo, and P. H. Grierson in County Carlow. 

 Later it came to be regarded by us as almost the commonest 

 Vertigo in the Dog's Bay district, Mr. Stauden taking 36 

 specimens off a single piece of disintegrating felspar, which 

 stone it seemed to prefer, and on which it was very hard to 

 see. Vertigo Lilljeborgi was found living sparingly in the 

 rejectamenta from Cregduff Lough, in company with V. 

 antivertigo and V substriata, the dead stems of Scirpus 

 lacustris and the roots of Kriocaulon being its favourite hiding 

 place. The discovery of this habitat in 1902 also belongs to 



1 /. N., Jan., 1903 2 /. N., Sept., 1895.
