with this species than with any other ; their chief peculiarity being 

 their cylindrical form and the backward direction of the curved 

 crown. Both these specimens were obtained from the Freshwater 

 Bed at West Eunton. 



Leuciscus cephalus ? — A pharyngeal bone with several teeth, pre- 

 served in the Gr^en Collection at the Natural History Branch of the 

 British Museum, Cromwell Eoad, there is little doubt, belongs to this 

 species ; but as it was obtained from Ostend, there is some question 

 as to whether its true horizon is not really much above the Forest Bed. 



Leuciscus rutilus. — Three or four nearly perfect pharyngeal bones, 

 but without teeth, and a large number of isolated teeth, are referable 

 to this species. Most of them are from the West Eunton Fresh- 

 water Bed, and are in Mr. Savin's collection at Cromer. 



Leuciscus erythrophthalmus. — Among the numerous isolated teeth 

 referable to the genus Leuciscus there are several which are believed 

 to belong to this species, but there is one in the Museum of Practical 

 Geology from the West Eunton Freshwater Bed, which is held to 

 be undoubted evidence of its occurrence. 



Ahramis brama. — Two unworn teeth from West Eunton 

 present the peculiar groove under the apex which is seen in the 

 pharyngeal teeth of the Bream, and so far as I know in these 

 alone. 



Tinea vulgaris. — Several short teeth with broad crowns and small 

 pedicles evidently belong to this species ; they are all from the West 

 Eunton Freshwater Bed, and are now in Mr. Savin's collection and 

 in the Museum of Practical Geology. 



Gadus morrhua. — This species is represented by portions of 

 jaws from the " Forest Bed " of several localities, and specimens 

 are to be seen in Mr. Savin's collection, and in the British and 

 Jermyn Street Museums. 



Gadus pollachius. — Two portions of otoliths from the Weybourne 

 Crag at Eunton are belieA^ed to belong to this species. Examples of 

 two other forms of otoliths have also been found which have not 

 yet been determined ; although probably belonging to the same genus, 

 they certainly do not belong to either of the species known from the 

 Forest Bed. 



Galeus canis. — This genus and species is represented by a single 

 but characteristic tooth from the Weybourne Crag of Eunton. 



Acanthias vulgaris. — This form is also represented by a single 

 tooth, from the Weybourne Crag of Eunton, and like the last is now 

 for the first time known in the fossil state. 



Baja hatis. — Numerous teeth from the Weybourne Crag at Eunton 

 evidently belong to one of the Skates ; and several can be identified 

 with the Raja hatis. 



Raja clavata ? — Several teeth obtained with the last species agree 

 closely with the two forms of teeth found in the male and female 

 Tlwrnhach and are with some reserve placed in that species. 



Examples of all the above "Forest Bed " Fish, with the exception 

 of Bar-bus vulgaris and Leuciscus cephalus, are to be seen in the 

 Museum of Practical Geology.
