88 PROCEEDINGS OF THE 



the rarer shells characterising the glacial dejDosits of the Clyde 

 district, and contained about thirty species. The most abundant 

 of these are Cyprina Islandica and Peden Islandicus, the latter being 

 extinct as a recent shell in the British seas. Mr John Young 

 made some remarks on Mr Robertson's interesting discovery, 

 stating that the collection exhibited was acquired during several 

 visits to the locality by Mr Robertson, Mr R. Gray, and himself. 

 The clay beds containing the shells had been found to extend a 

 considerable distance along the shore, their existence being easily 

 traced by the washed-out fragments on the beach for upwards of 

 a mile east of the village. At some places the specimens are in 

 excellent preservation, those of Panopma Norvegica being quite 

 entire. There were also numerous fragments of the plates and 

 spines of an Echinus, which, so far as can be made out, appear to 

 be portions of Echinus lividus — a species not now found alive in 

 any part of Scotland. 



Mr Young then drew the notice of the meeting to a series 

 of beautifully preserved minute organisms from the glacial 

 beds at Fairlie, near Largs. The material from which they were 

 collected was found filling up the interiors of some of the larger 

 shells — Pecten mciximus, etc. — obtained from that locality by Mr 

 Robertson. From these shells Mr Young had taken specimens of 

 the following genera of Foraminifera : — Polystomella, Rotcilia, 

 Lobatula, Numulina, and Miliola; also, four or five forms of 

 Entomostraca, and several species of univalve and bivalve shells, 

 none of which have hitherto been recorded as occurring in the 

 glacial deposits of the Clyde. He also referred to the discovery 

 of other shells and minute organisms in the same beds by Mr 

 Robertson, observing, in concluding his remarks, that the list of 

 glacial shells was likely to be greatly augmented by a more minute 

 investigation of the beds in all the localities where they occur. 

 This section of the proceedings appeared to possess a great degree 

 of interest. 



Mr Thomas Chapman exhibited two cases of North American 

 Lepidoptera, which he had just received from a correspondent, 

 containing many species identical with those of this country, after 

 which the President referred to three fine plants on the table which 

 were exhibited by Mr Peter Clark, of the Royal Botanic Garden, 

 the species being Ainaryllis Johnsoni, Aloe ccesia, and Vriesia 

 speciosa, all in flower.
