two intermaxillaries. The jaws have 28 . 28 teeth, of which two are 

 in the intermaxillary bones. The teeth are conical, acute, rather far 

 apart. The tympanic bone is two-lobed, as in Ddphinus. The petrous 

 bones are without apophysis. The lower jaw is very high behind and 

 curved, giving it the appearance of a Ziphiics." — Van Beneden.

Dr. Wagner (Supp. Schreber's Siiugeth. vii. 305) has given the 

 name of Delphinus carhonarius to " the Blackfish of the South-Sea 

 whalers," described and figured in Bennett's ' Narrative of a Whaling 

 Voyage,' ii. 233. fig., copied Wagner, tab. 352. f. 1.

At the end of remarks on the genus, add : — 



Several porpoises caught on the coast of England have been lately 

 examined, and they all have spines or tubercles on the upper edge 

 of the dorsal fin. The specimens without these ajjines or tubercles 

 are desiderata, and one is almost led to the belief that they do not 

 exist ; but it is difiiciilt to prove a negative, and one can hardly 

 beheve, if they are always present, that so many zoologists should 

 have overlooked them. The stuifed specimen in the Museum shows 

 them very indistinctly, if at all ; but then, stuffed specimens are so 

 mauled and rubbed with pumice and other material, that they may 

 have been rubbed off; and they are so covered with varnish that they 

 may have been hidden. So the existence of a porpoise vsdthout spines 

 must be left for future research. The differences discovered by various 

 anatomists seem to show that there must be more than one species 

 included under the name of P. communis, which are very like ex- 

 ternally, but this is probably the case with several Dolphins, Bottle- 

 noses, and Porpoises.
