Mr. Symers M. Macvicar exhibited Myurium Hehridarum^ 

 Schp., from Moidart. This moss has been found in North Uist, 

 South Uist, Benbecula, Barra, Skye, and Tiree. The specimen 

 exhibited on the present occasion, from Moidart, in the extreme 

 south-west of Inverness-shire, is the first known locality on the 

 mainland. Mr. Macvicar had lately found it in three localities 

 some miles apart, in each instance in the same kind of place — 

 namely, wet, stony ground close to the shore. In the station 

 where it is most plentiful, it occurs in company with Schoenus 

 nigricans, Linn., among stones, and on tussocks of Festuca ovina, 

 Linn., with Ling heather. Surrounding the tussocks is the 

 wetter ground, with Hypniim revolvens, Sw., II. scorpioides, Linn., 

 and Aneura pinguis, Dum. This species has been said to occur 

 on rocks, but from the localities in which Mr. Macvicar has seen 

 it, he would not call it a rock-plant, as there is always a con- 

 siderable amount of soil between it and the rock, and in this 

 respect it differs from such a species as Grimmia maritima, Turn. 

 Myurium belongs to the Atlantic type of plants, being limited to 

 the west of Britain, the localities above mentioned being the only- 

 stations known for it in the British Isles. It is not known from 

 any other part of Europe, but has been found in the Canaries and 

 Azores. Mr. Macvicar thinks that it will probably be found in 

 the west of Ireland when the coast there has been searched 

 further. It grows in compact patches of a few inches in 

 diameter, of a golden-yellow colour, somewhat in the manner of 

 Leucohryum glaucum, Schp. The only plant it could possibly be 

 passed over for is Hypnum cupressiforme, Linn., var. 9 elatum, 

 B. and S. ; but when once known it is easily recognisable at 

 sight, and under the lens no mistake is probable. 



Mr. George W. Ord read a paper on " The Lepidoptera in rela- 

 tion to Flowers. (See page 355.) 



The President (Mr. Kidston) showed with the lantern, some 

 photo-micrographs of insects and plants. 



Mr. Robert M. Morton gave a lantern exhibit of native plants 

 in their habitats.
