252 PROCEEDINGS OF THE 



106 genera, and 244 species and varieties, testified to the 

 wonderful mildness of the past winter. 



Mr David Eobertson,- F.G.S., and Mr John Young, F.G.S., 

 exhibited a series of small recent land and fresh-water shells, 

 from Hairmyres, East Kilbride, which they had obtained last 

 month in the washings of some of the weathered fossiliferous 

 limestone shales from that district. Mr Young stated that their 

 object in bringing these shells before the Society, was for the 

 purpose of indicating a locality which gave promise of yielding a 

 considerable number of Scottish land and fresh-water mollusca. 

 The spot where they were obtained is at the Curling Pond, near 

 the Railway Station, and although the object of search was not 

 this class of organisms, yet it was interesting to state that, in the 

 small quantity of material which had been examined, and which 

 was only collected over a few feet of surface, there should occur 

 some fifteen species of recent shells, one of which had not 

 formerly been recorded as found in the Glasgow district, viz., 

 Vertigo 'pijfjmma. This shell, however, had been found on the coast 

 at Largs, and at Bute, by the late Mr AVilliam Haddin, a member 

 of the Society. Mr Young had no doubt that if a careful search 

 was made in the above locality during the summer and autumn 

 months, an enlarged collection of these interesting shells could 

 easily be formed. 



The President exhibited a number of specimens of finely 

 preserved Carboniferous polyzoa, from the collection of Mr John 

 Young, F.G.S., and made some observations on the structure of 

 their neAV genus, Rhuhdomeson, of which they had discovered two 

 species; the genus being founded upon the organisms formerly 

 known as Ceriopora (jrac'Uis and C. rhombifera of Phillips. He 

 also explained the structure of the star-mouthed cells in the newly 

 discovered i^mius A dinostoma fenestrat am, and in a new species of 

 Glauconome, which had been provisionally named G. steUipora, the 

 specimens being all from the limestone strata of the West of 

 Scotland. A number of large and beautiful photographs of slabs 

 of polyzoa, crinoidea, and shells, executed by Mr Thomas Annan, 

 Sauchichall Street, were exhibited by the President as illilstrative 

 of what could be done by photography in producing faithful 

 pictures of the numerous and varied organisms that crowd many 

 of our limestone shales.
