The shell was carefully stored away and we again examined 

 it lately, comparing it with various forms of Helix pisana 

 and Helix virgata, from the counties south of Carlingford 

 Lough. It was so different in many respects that we sent it 

 to various experts for their opinions, which varied a good 

 deal. The shell being immature made its determination 

 evidently very difficult. Finally we sent it to Mr. A. S. 

 Kennard, F.G.S., of the Conchological Society, London, in 

 order that he might compare it with some from South-West 

 Europe in the British Museum. This he kindly did, with 

 the assistance of Messrs. Edgar A. Smith and B. B. Wood- 

 ward, and I cannot do better than give Mr. Kennard's 

 remarks on the search: "It was a great treat to name the 

 shell. We at once rejected Helix virgata as clean out of it; 

 it was a young shell, perhaps two-thirds grown, so it could not 

 be that species. When we examined it with a lens and saw 

 the fine strice we rejected Helix pisana. Then came the ques- 

 tion — What is it ? Our first surmise was ■ Helicella affinior, 

 Debleaux, from Oran (Algiers), but it was not that, though 

 near to it ; a similar result was meted out to Helix cyclostoma, 

 Bourg, from Oran. We could see after this that its affinities 

 were North African, and then we found Helicella zakkarensts, 

 Kobelt, from Dral-el-miyan, Kabylie, Algiers, and we cannot 

 separate it from that form." This final search was in the 

 fine Canon Norman collection which is now in the Natural 

 History Museum. Helicella zakkarensis we see, from speci- 

 mens kindly forwarded to us by Messrs. Sowerby and Fulton, 

 to be much larger even than Helix pisana, the shell is not so 

 high in the spire and the umbilicus is much broader. The 

 larger specimen sent us measures 26 mm., a typical Helix 

 pisana only 18^ mm. We hope to visit the locality and make 

 a keen search to settle the question of its being possibly only 

 an accidental introduction. 



Mr. George C. Gough, A.R.C.S., F.G.S., then read a 

 paper entitled " Geology and Scenery." He said the study of 

 scenery was of interest to many besides the geologist. Scenery 

 depended on geology, either directly or indirectly, and geology
