30159a. Numerous fragments of the maxilla and mandible, with 
the cheek-teeth ; from the Headon beds (Upper Eocene) 
of Hordweil, Hants. These teeth apparently agree pre- 
cisely with those of the continental specimens of 7. 
aquatilis. Hastings Collection. Purchased, 1855. 
25228. Cranium, with the cheek-teeth in a very much worn con- 
dition; from the Headon beds of Hordwell. Owing to 
their worn condition the cheek-teeth of this specimen do 
not exhibit the characteristic marking; but from the 
resemblance of the specimen in other respects to the 
eranium of 7’. aquaitilis, there seems little doubt but that 
it belongs to the same species. 
Presented by S. V. Wood, Esq., 1850.

Presented by S. Laing, Esq., 1862. 
40212. The greater part of the right ramus of the mandible of a
