XXXIX. — On some new Genera and Species of Fossil Fishes. 

 By Sir Philip Grey Egertox, Bart., F.R.S. &c. 



To the Editors of the Annals of Natural History. 



Gentlemen, 

 In the early part of last year I was solicited to undertake the 

 preparation of a second Decade of fossil fishes for the Memoirs of 

 the Geological Survey of the United Kingdom. Having mate- 

 rials at hand I completed the task assigned to me, and delivered 

 in the manuscript in the commencement of the month of July. 

 In consequence however of a press of husiness in the Stationery 

 Office, I have not yet received the proofs for correction, nor, as 

 far as I have been able to learn, is there any likelihood of the 

 matter being proceeded with for some time to come. The ma- 

 nuscript contains the detailed descriptions of twelve new species, 

 comprising three new genera ; most of them from the Purbeck 

 beds and the Lias. The delay of publication of these materials 

 having almost reached twelve months, I am induced to ask for a 

 vacant space in youi* Magazine for the following short descrip- 

 tions of the species, in order that ]\Ir. IVIorris and others, who 

 have works in progress on British Palaeontology, may be put in 

 possession of these additions to our fossil fauna. 



Genus Asteracanthus, Agassiz. 



A. granulosus, Egerton. An ichthyodorulite about 1 foot in 

 length, characterized by the small size of the tubercles orna- 

 menting the exposed portion of the spine. 



Locality. Hastings sand, Tilgate Forest. Decade 8. pi. 1. 



A. verrucosus, Egerton. An ichthyodorulite of common oc- 

 currence at Swanage. The surface is closely beset with stelliform 

 tubercles rising from circular expanded pedestals. 



Locality. Purbeck beds, Swanage. Decade 8. pi. 2.
