IV. — Alphabetical Catalogue of Type Specimens of Fossil 

 Fishes in the British Museum.^ 



By "Wm. Davies, 

 Of the Department of Geology, British Museum. 



THE fine series of Fossil Fishes in the National collection is ex- 

 hibited in and constitutes the principal feature of Eoom II. in. the 

 Northern Geological Gallery. The arrangement adopted is in accord- 

 ance with the classification of Prof. L. Agassiz, as indicated in his 

 great work, "Eecherches sur les Poissons Fossiles," but with such 

 modifications as the subsequent investigations of ichthyologists have 

 rendered necessary. These modifications occur chiefly among the 

 fishes of the older formations. 



Of the four divisions or Orders of Fossil Fishes, — viz., the Placoid, 

 Ganoid, Ctenoid, and Cycloid — divisions founded upon the form or 

 structure of their scales or dermal covering, the first (the Placoids) 

 are arranged in table cases on the north side of the room, in cases in 



1 Having already published in the pages of this Magazine, lists of the types of 

 Fossil Fishes in two of the grandest private collections in this country, namely, that 

 of Sir Philip de Malpas Grey Egerton, Bart., M.P., F.R.S. (see Geol. Mag. 1869. 

 Vol. VI pp. 408-413), and that of the Earl of Enniskillen, F.R.S. (see same volume, 

 pp. -556-561), it seemed desirable to complete as far as possible these valuable synopses 

 of Fossil Fishes by the publication of the types in the British Museum. I therefore 

 requested Mr. W. Davies, who has for many years made careful notes of the typical 

 and figured specimens of the Fossil Vertebrates in the collection, to do me the favour 

 to draw up for this Journal the accompanying particulars of our grand National collec- 

 tion, which 1 feel sure cannot but be most acceptable to palseontologists. — H."W.
