REMAINS OF GYRODUS FROM THE CORAL RAG 

 OF EAST YORKSHIRE. 



I HAVE recently obtained from the well-known quarry at 

 North Grimston, a palate with teeth of a" species of Gyrodus. 

 In this genus the palatine and vomerine bones are united by 

 fine longitudinal rows of teeth. The largest teeth are in the 

 middle row, and are almost, but not quite, circular, each having a 

 depression and a papilla in the middle. The teeth of the outer 

 row are slightly pentagonal, and are highest on the outside — the 

 inside being almost level with the palate. Each tooth is provided 

 with two circular sets of papillae — one within the other.

 Robinson, J. Hollingworth, R. H. Philip, T. Audas, and

 ensuring the present successful position of the Club ; they are all 

 still prominent members, and it is to be hoped may long be spared 

 to be so.
