DESCRIPTION OF A 



the contiguity of the teeth, so that the teeth of 

 both jaws must have opposed their surfaces to each 

 other, there being no intermediate space, as descri- 

 bed in the Grampus and Dolphin, for the recep- 

 tion of the teeth of the opposite jaw. All the teeth 

 I have examined, except one, have nearly a flat sur- 

 face, some a little sloping or obliquely truncated, 

 and quite flat ; others truncated at right angles, and 

 slightly convex, and one, not half so large as any 

 other, is obtusely conic ; this appears from the cor- 

 responding sockets to have been a fore-tooth ; for 

 in the upper jaw there are two small sockets in the 

 front, and in the lower jaw four ; but even these 

 could scarcely protrude beyond the flesh, as not 

 above a quarter of an inch projects above the jaw- 

 bone when placed in the socket. The hinder teeth 

 appear to have stood nearly perpendicular ; others 

 evidently stood obliquely forwards, both by the ap- 

 pearance of the teeth and the sockets ; and I am 

 of opinion, that none of the teeth, the six smaller 

 ones before mentioned excepted, could have been 

 scarcely elevated above the gums, both by the ap- 

 pearance of the teeth themselves, and by replacing 

 them in their sockets. 



The blow-hole in the skull is situated as descri- 

 bed by Mr Cornish, but a central septum or lon- 

 gitudinal division, cuts the aperture into two equal 

 parts. 



By comparing the number, disposition and shape 

 of the teeth of this species, with those of the gram-
