Ilie following measurements will show the relationbetween the 

 genus Ko(jia and tins new genus JEiipliysetes. 



Kogia. 



Euplvjsetes. 



Total length of skull 



Greatest breadth of ditto 



Breadth of ditto at notches 



Length of beak 



Breadth of ditto at notches 



Length of under jaw 



Width apart of condyles of ditto 

 Length of the symphysis 



As our animal, therefore, comes obviously near to the Kogia 

 hreviceps of Gray, who founded the genus on the description by 

 De Blainville of a skull of his Physeter Ireviceps, it may be 

 incumbent on me to state w"hy a new name has been adopted, 

 namely, Euphysetes Grayii. 



In the first place, the jawbone o£ our animal is not as broad 

 as long. The nasal pit is totally unlike that of the cachalot. 

 The nose (if by nose be meant snout) is not pointed, but very 

 truncated or blunt in the skeleton as well as in the perfect 

 animal ; moreover, instead of the nose being one inch longer 

 than breadth of occipital bone, this is to the length of snout in the 

 proportion of about fourteen to eight. The teeth, instead of being 

 fourteen or fifteen, are in number twenty-six. Again, the beak, 

 instead of being as long as it is wide at the notches, has its length 

 in proportion to this width only in theproportion of seven to nine, 

 and so on. The few characters given by De Blainville and Gray 

 show sufficient divergency from the form of our animal, and they 

 incline me to leave the name Kogia hreviceps for the whale that 

 may be found to suit the above description of it as recorded by
