ZOOLOGY. 



Land and Freshwater Mollusca. — The report published 

 in the Irish Naturalist, September, 1904, by Mr. Robert J. 

 Welch and myself, on the Mollusca of this district, may be taken 

 as still up to date. The only additions to the list of species 

 contained therein, that I am aware of, are as follows : — 



Limax flavus L. Occurs in the village of Drumahaire. 

 There is no evidence that it is native in the district. 



Zonitoides excavatus (Bean). A special search was made for 

 this shell by Mr. Foster and myself in April, 19 14, which resulted 

 in the finding of one typical example under a rotten log, near the 

 eastern boundary of Slish Wood, by the edge of a small lake. 

 The finding of this shell in the district is particularly welcome, 

 since it is not only an addition to the fauna of Sligo, but to this 

 part of Ireland. Its presence in Slish Wood must be put down 

 to the fact that metamorphic rocks form the range of hills south 

 of Lough Gill, as the species is one which appears to avoid the 

 limestone areas. The nearest known habitats for it are at Ardara,
