President's Address. 35 



The "Fossil Concliology" is cliielly useful to Scutch Taho 

 ontologists for the list of shells horn tlie Closeburn limestone 

 in Dumfriesshire. The fossils, as in the case of those de- 

 scribed l)y J. Sowerby, were collected Ijy Mr C. S. Menteith. 



Omitting the names of fossils previously described from 

 Scotch localities by the Sowei'bys or Fleming, the following 

 are Captain Brown's twelve additions to tlie list : 



Orthoccras cinctum (^^^y-)y 



Spirifera glabra (Martin), 



„ lata (Brown), 



Productus Martini (Sby.), 



„ latissimiis „ 



„ gigayitcus „ 



Avicula modioliforme (Brown), 



TJnio Gerardi „ 



„ Bhindii „ 



„ nucleus „ 



„ fyramidalus „ 



„ 'polmontcnsis „ 



Closeburn. 

 Arran, 



Fife. 



Woodhall.

We had occasion, when dealing with the Silurian shells of 

 Scotland, to refer to M'Coy's great work on " The British 

 PalaBozoic Fossils." The third "Fasciculus,"* published in 

 1855, has the merit of giving the first detailed and scientific 

 description of many sj)ecies of shells collected from Scotcli 

 Carboniferous rocks ; many localities are likewise men- 

 tioned. 



In 1857 a new era for British Carboniferous Pala?ontology 

 was ushered in by the appearance of the first part of Mr 

 Davidson's " Monograph of the British Carboniferous Bra- 

 chiopoda."-|- It comj^rises five sub-parts, and was published 

 between the years 1857-63, containing fifty-five lithographic 

 plates all executed by the author in his usually accurate and 

 graphic style. It contains an excellent table, showing the 

 geographical distribution of the British Carboniferous Bra- 

 chiopoda. Almost concurrently with the monograph, Mr 

 Davidson wrote a lengthy paper for the "Geologist":!: on 



* Pp. 407-644. t Pp. 280, pis. 55, 4to, London, 1857-63.
