Io6 THE SCOTTISH NATURALIST 



MOLLUSCAN INVESTIGATION IN WESTERNESS. 



By Fred Booth. 



[This is the third of the series of notes on investigation of the northern 

 range of mollusca in Scotland, undertaken by aid of a Government 

 grant. W. D. R.] 



My investigation was continued in the district around 

 Glenelg on 6th, 7th, 8th, and 9th August 1910. 



The physical features of the Glenelg area are much the 

 same as at Gairloch (see West Ross paper, Scot. Nat., 

 March 191 3, p 56-57). The lower parts of the Glenmore 

 and Glenbeg valleys are well wooded, especially the latter. 

 In the higher parts the trees become short and stunted. 

 The tops of the mountains are rugged and nearly devoid of 

 vegetation, what little there is to be seen being chiefly Erica 

 cinerea and lichens. The wooded portion of the lower end of 

 the Glenbeg valley is densely covered with undergrowth of a 

 varied character, and carefully fenced from the road with 

 barbed wire. The streams from the mountains in this valley 

 are very steep, coming down in a succession of waterfalls and 

 cascades, those from Beinn a Chapuill being very pre- 

 cipitous. The plant life inhabiting the boggy ground, both 

 in the woods, on the slopes of the hills, and on the sea beach, 

 is practically the same in character as at Skye and at Gair- 

 loch. The shore is rock and shingle. There is one small 

 pine-wood in the village, the rest of the woodland being of a 

 mixed character similar to that of the Gairloch woods. On 

 some of the mountain slopes new plantations of pine and 

 larch had been planted. 



Limax maximus. One adult of var. fasa'ata, in larch plantation 



near the village, 9th August 19 10. 

 Limax arborum. Two, immature, near Pictish Towers, Glenbeg 



valley, 7th August. 

 Agriolimax agrestis. In several places. Common in gardens in 



the village.
