NATURAL HISTORY SOCIETY OF GLASGOW. 71 



and upwards of forty species. In illustrating his paper, Mr 

 Young brought forward, among others, the following genera: — 

 Naticopsis, Eul'ma, Loxonema, Macrocheikis, Euomphalus, Pkuroto- 

 maria, Murchisonia PlaUjceras, Dental mm, Chiton, Chitonellus, Por- 

 cellia, and Bellerophon. These embraced a large number of species 

 admirably preserved and mounted. In the case of Naticopsis it is 

 interesting to find the colours yet visible in the shells; and among 

 the Euompjhali, Mr Young mentioned in connection with Carbon- 

 arius, that he had collected in one evening, at a quarry in Een- 

 frewshire, one hundred and forty specimens. In concluding his 

 remarks, he alluded to the necessity that exists for a thorough 

 investiffiition of the British carboniferous univalves, as in their 

 present state of classification it is not easy to fix the precise limits 

 of many of the genera, and still more difl&cult to refer to doubtful 

 species, owing to the varieties of form they often assume in diffe- 

 rent districts. Mr Young also drew attention to a specimen of 

 Conularia qiiadri-sulcatus, in the collection upon the table, as a rare 

 shell in Scottish districts. 



Dr Lindsay then addressed the meeting at the close of the busi- 

 ness, and made some remarks on the success which had attended 

 the meetings of the session now concluded. He observed that 

 since the formation of the society, twelve years ago, its prospects 

 had never been in so satisfactory a state. While acknowledging 

 the many valuable contributions of those gentlemen who had, by 

 the exhibition of specimens and the reading of papers, aided the 

 advancement of the society's interests, he would now state what 

 he believed all the members already felt, that much of that success 

 had resulted from the exertions of their Secretary, who had lab- 

 oured successfully to place the society on a more satisfactory posi- 

 tion than it had hitherto occupied. He begged, therefore, to move 

 the following resolution: — "That the members of the Natural 

 History Society of Glasgow, on this the last meeting of the Session 

 18G2-3, unite in expressing a sense of their obligations to Mr 

 Robert Gray, their Secretary, for the continued and sustained 

 efforts he has made to secure and advance the Society's interests; 

 in acknowledgment of which they tender him their cordial thanks, 

 and further move that the same be recorded in the minutes of the 

 society." 



The resolution having been seconded by Mr Thomas Chapman, 

 was cordially and unanimously agreed to.
