 Hugli Colqulioun, M.D., President, in the chair. 



SPECIMENS EXHIBITED. 



Curlew-billed Sandpiper {Tringa snharquata) and Storm Petrel 

 (Thalassidroma pelagica), both from the Firth of Forth, for- 

 warded by Mr John A. Harvie Brown, corresponding member. 

 Mr Brown also sent for exhil)ition a specimen of the Common 

 Dunlin {Tringa variahilis), which had Ijeen procured in the island 

 of North Uist by Mr Gray. It was in full breeding plumage, and 

 had been shot from the nest. The bird, when contrasted with 

 others of the same species from different localities, appeared to be 

 little more than half the size. Mr Gray explained that from 

 l)ersonal observation he was disposed to think that the dunlins of 

 the Outer Hebrides belonged to a northern race of that species, 

 and were of much smaller dimensions, resembling very much in 

 size and general features the Little Stint [Tringa minuta). 



Dr James Stirton exhibited specimens of the following mosses : 

 — Brachythecium Hunti and Hypnum Breaclalhanese, both new 

 to science; and Leskea nervosa, new to Britain — all from Ben 

 Lawers. 



Mr J. Gilmour exhibited a specimen of the common rabbit, 

 showing a curious malformation of the teeth. 



Mr Gavin Miller exhibited a complete specimen of Productus 

 scabriadus (Martin), which was obtained from a bed of boulder 

 clay, at a depth of ten feet from the surface, in digging the 

 foundation for a building near Windsor Terrace. 



The Secretary exhibited a rare Cystldean (Ischadites Kanigii), 

 which he had collected from the silurian rocks of the Girvan district 

 in Ayrshire. 



Mr John Young made some remarks on these fossils, and stated 

 that the Productus shell in the boulder sill must have been originally 

 derived from some of the beds of fossiliferous limestone shale 

 belonging to the carboniferous period, which exist to the north and 

 west of Glasgow, flanking the trap hills of the Campsie and 

 Kilpatrick range. He had often met with boulders of the fossili- 

 ferous limestones and ironstones of this period in the glacial drift, 

 but he had never seen so perfect an example of a shell as the 

 specimen exhibited. The geological relation of the Cystidean
