62 CEXACEA. 



28980. A tooth with the crown broken off; from the Red Crag of 

 Suffolk. This specimen agrees precisely with the one 

 figured by Gervais and already referred to. 



Purchased, 1854. 



44617. The imperfect root of a tooth, agreeing with the preceding^ 

 specimen ; from the Eed Crag of Suffolk. 



Purchased, 1873. 



Hoplocetus curvidens, Gervais 1 . 



In this species the roots of the teeth are nearly as much curved 

 as in H. borgerhoutensis, but are much thicker, and the groovings on 

 the enamel are more distinct. 



Hob. Europe (Belgium and [?] England). 



39024. The upper half of a much-rolled tooth, provisionally referred 

 to this species ; from the Red Crag of Eelixstowe, Suffolk. 

 This specimen appears to agree very closely with the type 

 tooth figured by Gervais in the ' Osteographie des Cetaces,' 

 pi. xx. fig. 25, and shows a remnant of the enamel with 

 its basal constriction. 



Bowerlank Collection. Purchased, 1865. 



49979. A similar fragment of a rather smaller rolled tooth ; from 

 the Red Crag of Suffolk. 



Weiherell Collection. Purchased, 1871. 



The following specimens agree in size and characters with the vertebrae 

 of Kogia breviceps, and may therefore be probably referred either 

 to the present or one of the allied genera of small Physeteroids, 

 unless they indicate the occurrence of Kogia itself. 



48487. A caudal vertebra in a rolled condition and wanting both 



epiphyses ; from the Red Crag of Suffolk. This specimen 

 agrees very closely with the seventh and eighth caudals of 

 Kogia. Purchased, 1875. 



48488. A rolled sixth (?) caudal vertebra, wanting both epiphyses ; 



from the Red Crag. This specimen is almost indistin- 

 guishable from the sixth caudal of Kogia. 



Purchased, 1875.
