42 PROCEEDINGS OF THE 



time lie liad ever seen the plant growing, and he had no doubt it 

 had been introduced with seed corn, and would likely establish 

 itself in Cumbrae, for in a neighbouring field they found the 

 Penny cress (Thlasjn arvensis), also a denizen of the east, but 

 which is seldom seen in the west, excepting occasionally on ballast 

 or rubbish heaps. 



On the 10th of the month they visited Benlomond, but 

 neither in ascending nor descending the mountain was anything 

 met with that they had not seen there before. One of the 

 party, however, who in coming down had taken a different 

 route from the others, succeeded in picking up specimens of three 

 plants worthy of notice. The Holly fern (Polystichum loncldtis), is 

 chiefly found on the highest mountains of Scotland and Wales. 

 It was last summer reported as having been got on Benvoirlich, 

 but it has not hitherto been recorded as found on Benlomond. 

 The next to be noticed, Potentllla aljiestris, is a very attractive 

 species, with deep rich, golden yellow flowers, and the only stations 

 given for it in the " British Flora " are the Clova and Breadalbane 

 mountains. The third noticeable species was Arenaria veriia, 

 which is quite common in the east, growing plentifully on Arthur's 

 Seat and the Corstorphine hills, but not recorded hitherto as 

 found in the west. It is noticeable that neither of these plants, 

 nor Sihhaldia inocumhcns, which grows abundantly on the mountain, 

 are mentioned in Kennedy's ^' Clydesdale Flora," although Ben- 

 lomond comes within the range of its stations.

SPECIMENS EXHIBITED. 



Mr Francis G. Binnie exhibited two specimens of Trichoptera, 

 united by authors under the llalesiis digitatiis of Schrank, and 

 remarked that three species arc confused under this name, two of 

 which — viz., those exhibited — seem to be British. The first, 

 H. radiaius, Curt., is not uncommon by the Clyde at Carmyle, and 

 by the Allander, also in the vicinity of the Cloch. The second,
