SPECIMENS EXHIBITED. 



The Chairman exhibited a living specimen of a rare sea anemone 

 — Peachia trij^hyUa — from C umbrae, in the Firtli of Clyde. Mr 

 Gosse, in his work on this class of Zoophytes, gives the Channel 

 Islands as the habitat of the species. He had never seen it 

 himself, both descriptions and drawings having been supplied to 

 him by Dr Wallich. Mr Rol)ertson described the habits of the 

 creature in captivity, regarding which nothing appears to have 

 previously been noticed. 



Mr Robertson also exhibited two Nudibranchs, new to Scotland, 

 namely, Doris proxima and Eolis glauca, both from Cumbrae — the 

 former having hitherto been considered peculiar to the Mersey, 

 and the latter to the Devonshire coast. He likewise described 

 the Jiabits of both in confinement, and their distinguishing 

 characteristics, and explained the means by which he had been 

 enabled to keep them alive so as to observe their movements. 



Dr W. L. Stewart, of Bothwell, exhibited a collection of reptiles, 

 insects, and Arachnidce from Western Africa. Among these were 

 conspicuous a scorpion, remarkable for its great size, and a 

 double-headed snake; the whole of the objects being in a beauti- 

 ful state of preservation. 



The Secretary drew the attention of the meeting to a very 

 interesting series of British birds' nests and eggs, which had been 

 sent for exhibition by Mr James Thomson, late of Dunmore. 

 The collection, prepared by Mr Thomson himself, was distinguished 

 for gr^at neatness and accuracy in its arrangement. 



Mr James Dairon exhibited a series of GraptoUtes from the 

 Silui'ian shales of the Moffat district, belonging to the genera 

 Ch-aptolites, Diplograpsus, Didijmograpsus, Dichograpsns, and Rastrites. 

 In the course of his remarks, Mr Dairon pointed out some of the 

 pliysical features of the Moffat district and the nature of the strata
