what Prof. Nicol has done for the geology of the north of Scotland, 

 As we have never been in Grlen Torridon, or seen the beauties of the 

 Grair loch, we are unable to judge of the accuracy of the author's 

 sections, and consequently of the position he takes in opposition to 

 the views of the officers of the Survey. In other matters he is at 

 variance with generally received opinions ; as, for instance, in regard 

 to the age of the Eed Sandstone beds at Elgin, which contain the 

 remains of the Stagonolepis, the origin of the parallel roads of Glenroy , 

 and the nature of the agency which produced the Boulder-clay.

GrEOLOGicAL SociETY OF LoNDON. — I. February 21, 1866. — Waring- 

 ton W. Smyth, Esq., President, in the chair. The following com- 

 munications were read : — 1. "On the Tertiary MoUusca of Jamaica." 

 By E. J. Lechmere Guppy, Esq. Communicated by Henry Wood- 

 ward, Esq., F.G.S. 



In 1862 Mr. Lucas Barrett deposited ia the British Museum a 

 collection of Miocene fossils, from Jamaica ; and the author having 

 described the nature of the beds whence the fossils were obtained, 

 remarked on the extended development of the Miocene formation 

 of the Caribbean area. From his examination of the fossils, he was 

 able to confirm many of the conclusions arrived at by Mr. Carrick 

 Moore, from his investigation of the San Domingo fossils, and by 

 Dr. Duncan's and Prof. Eupert Jones's investigation of the Corals 

 and Poraminifera of the West Indian Miocene deposits. 



The author considered that the Middle Tertiary beds of San 

 Domingo, Cuba, Cumana, and the Caroni series in Trinidad, together 

 :with the Miocene deposits of Jamaica, represent the upper or latter 

 part of the West Indian Miocene ; while the chert formation of 

 Antigua, the Anguilla beds, and the beds exposed at San Fernando 

 in Trinidad, belong to the lower and older part of the same 

 formation. 



Eeference was then made to the distinguishing features and cha- 

 racteristic fossils of the beds exposed in the several localities named ; 

 and in endeavouring to correlate the beds in the different islands, 

 the terms Upper and Lower Miocene were used merely as marking 

 what seems to be their relative antiquity. Out of sixty-one species 

 enumerated in this communication, thirty-four have been found to 

 be common to Jamaica and San Domingo, and fourteen to Jamaica 

 and Cumana. Thirteen species are ascertaiiied to be still living, 

 some of which have been found in the Miocene of Europe and other 

 localities. Several of the extinct species exhibit strong eastern 

 affinities ; but there is also a resemblance between a part of the 

 fauna and that now existing in the West Indies ; and a certain 

 number of the species are allied to European early and middle 

 Tertiary forms. The fauna as a whole is more nearly related to
