1. " On the Fossil Fish-reraahis from the Armagh Limestone in 

 the Collection of the Earl of Enniskillen." Bv James W. Davis, 

 Esq., F.G.S., F.L.S. 



The author described in this jjaper a large collection of fossil fish- 

 remains at present at Florence Court, Enniskillen, hut which will 

 soon he removed to the new Natural History Museum in the Cromwell 

 Road. The collection comprises, besides specimens collected by the 

 Earl of Enniskillen from the Carboniferous Limestone of Armagh, a 

 large series accpiired from the famous collection of the late Captain 

 Jones, M.P., tlie remaining portion of which is in the Geological 

 Museum of Cambridge. Several genera and species were described 

 by Prof. Agassiz in his ' Recherches sur les Poissons Fossiles ' 

 (1883-43), and again referred to by J. E. Portlock, F.R.S., in his 

 ' Report of the Geology of Londonderry and parts of Tyrone and 

 Fermanagh' (1SI3). 



In 1854 Prof. M'Coy described many new genera and species in 

 his work on the British Palasozoic Pcocks and Fossils, principally 

 derived from a study of the portion of Cajit. Jones's collection 

 deposited in the Cambridge Museum. Prof. Agassiz paid a visit to 

 Florence Court in 1858, and appended names to some of the fossil 

 teeth in Lord EnniskiUen's cabinets, intending to describe and figure 

 the new forms, and to revise the whole of his former work. His 

 death prevented this intention from being carried into effect. As 

 far as possible the determinations of Prof. Agassiz have been adhered 

 to in the present paper. 



The detached and isolated condition in which the remains are- 

 found renders anj' appreciation of the relationship of the teeth and 

 spines, or even of the teeth only, to each other extremely uncertain 

 and difficult. Some speculations as to the probable organization and 

 characteristics of the Carboniferous fishes which they represent, 

 evolved during a long consideration of the specimens, have therefore 

 been postponed to a future opportunity.
