NATURAL HISTORY SOCIETY OF GLASGOW. 31 



SPECIMENS EXHIBITED. 



Dr Young exhibited a model illustrating the anatomy of the 

 Polyzoa, recently prepared for the Hunterian Museum by IVIr 

 Fenwick, and made some remarks on the value of such models 

 for teaching purposes. 



Mr John Young, F.G.S., exhibited a series of specimens of a rare 

 bivalve shell, first discovered by Mr James Thomson, F.G.S., a 

 member of this Society, in Carboniferous limestone strata, in a 

 locality near Dairy, Ayrshire, and which has since been named 

 Posidonomya corrugata, sp.n., by Mr Etheridge of the Jermyn 

 Street Museum, London ; Mr Young stated that he had recently 

 obtained specimens of this interesting shell, in a second and new 

 locality, at a quarry near Boghead, south-west of Hamilton, and 

 made some remarks on Mr Thomson's discovery, as the earliest 

 recorded example of the genus Posidonomya found in this district.

The author of this paper stated that he had submitted the

 found to belong to species which he had named as follows: — 

 Climacammina antiqua, (Brady, M.S.) ; Endothyra Bowmanni, 

 (Phillips); Valvulina palceotrochiis, (Ehrenberg); Endothyra radiata, 

 (Brady, M.S.) ; several forms being left undetermined until further 

 sections were made to enable him to make out their exact rela- 

 tionship to some of the other fossil genera. Mr Young stated
