258 PROCEEDINGS OF THE 



jointly in the Proceedings of the Society, Mr Young stated 

 that in their investigation of these Carboniferous polyzoa they 

 had found, after close research, that many of the forms were 

 undescribed. In the genus Glauconome the following species were 

 new, and they had provisionally named them G. stellipora, G. mar- 

 ginalis, G. aspera, G. flexicarinata, G. retroflexa, and G. laxa. From 

 the limestone strata of the East Kilbride district they had also 

 found the following new species belonging to other genera : — 

 Adinostoma fenestixttmn, a polyzoon with star-mouthed cells, and 

 Sidcoretqwra porosa. Dr Rankin, of Carluke, had also sent them 

 a new and interesting species of Thamniscus, a genus of poly- 

 zoons, hitherto met with only in Permian strata. This species 

 they propose to name T. Ranhini, in honour of this able investi- 

 gator, who has so long and so carefully worked at the Palaeon- 

 tology of the Carluke district. There are other forms of Car- 

 boniferous polyzoa that still await investigation, and which they 

 hope to take up at some other time. They were indebted to 

 Mr James Thomson, F.G.S., and Mr David Robertson, F.G-.S., 

 both members of this Society, for the examination of many 

 interesting specimens in their collections, and they hoped that 

 these gentlemen, as well as other members, would continue their 

 researches amongst this interesting group, which is perhaps more 

 abundant, and in better preservation, in our strata, than in any 

 other Carboniferous district in the British Isles.

SPECIMENS EXHIBITED. 



Mr George E. Paterson exhibited and described a fine collection 

 of birds and eggs, which he had obtained in Shetland last sum- 

 mer. It embraced specimens of Richardson's Skua (Lestris rich- 

 ardsonii), showing a considerable variety of plumage ; the Black 

 Guillemot {Uria grylle), the Green Cormorant {Carho cormoraims), 

 and the Eider Duck (Somateria mollissima).
