maxillipeds of Crustacea. As ne"\y localities for these interesting 

 though obscure forms are being found, it is to be hoped that more 

 light will soon be thrown upon the true nature of their origin. 



Mr. Young also exhibited a series of beautiful plates he had 

 received from Mr. Thomas Davidson, F.RS., Brighton, illustrating 

 a number of new and rare forms of Carboniferous brachiopoda 

 from the West of Scotland, which he is preparing for the supple- 

 ment to his great work on the Fossil Brachiopoda of Great Britain, 

 upon which he has been busily engaged for the last 30 years. 

 Among the specimens figured in these plates, Mr. Young called the 

 attention of the members to a small species of Productus which he 

 had found at Brockley, near Lesmahagow, and to a small species of 

 Chonetes from Corrieburn, Campsie. The former had been 

 identified by Prof, de Koninck, of Liege, as his Procluctus Griffith-. 

 ianus, found first at Vise, in Belgium, but which has not previously 

 been recorded for Britain. The second had been identified by 

 Mr. Davidson as Chonetes gibberula (M'Coy), and also new to the 

 Scottish list.
