undertaken to describe their anatomical features to the 

 Society. 



Dr Traquair, in the absence of Mr Grieve, gave a short 

 description of some of the specimens which had been for- 

 warded for exhibition. 



V. Dr Traquair exhibited a tooth of Archichthys sulcidens 

 (Hancock and Atthey), from the roof shale of the splint 

 coal seam at Smeaton, near Dalkeith. Archichthys, of which 

 only one species is as yet known, is a characteristic fish of 

 the true coal measures, and is allied to Bhizodus, differing 

 from it, however, in the absence of cutting edges in the 

 laniary teeth. It is abundant in Northumberland, occurring 

 also in Lancashire ; but is now, for the first time, recorded 

 from one of the Scottish coal-fields. 



VI. Ornithological Notes : (1.) Buteo lagopus, Rough-lcggcd Baz- 

 zccrd; (2.) Mergulus melanoleucos, Little Auk; (3.) 

 Larus glaucus. Glaucous Gidl. (Specimens exhibited.) 

 By John Alexander Smith, M.D. 



(1.) Buteo lagopus, Eough-legged Buzzard. — A male bird 

 shot in the Pentlaiid Hills, also a female from the same 

 locality, another from Yester, Haddingtonshire, in the months 

 of November and December. 



(2.) Mergulus melanoleucos, Little Auk. — One specimen 

 recently shot near North Berwick, another at Tyninghame, 

 and another from the Fife coast. The birds are winter visitors, 

 and have been probably driven inland by the easterly winds. 



(3.) Larus glaucus, Glaucous Gull. — Another of our winter 

 visitors. One was shot near Newhaven, and another near 

 North Berwick.
