WHITE-BEAKED DOLPHIN. 473 



Zoology of H. M. S. Erebus and Terror/' pi. 10. Both 

 the skin and skeleton of this specimen are now in the 

 British Museum, which also contains the skull of one 

 killed near Cromer by Mr. H. M. Upcher of Sherring- 

 ham Hall {Anii. and Mag. Nat. Hist. 18GG), and the 

 complete skeleton of an adult male taken a few years ago 

 on the south coast, but in what precise locality we have 

 been unable to learn ; an account of the anatomy of this 

 last example is given by Dr. Murie in the " Proceedings 

 of the LinuEcan Society " for 1871. 



This species is a native of the North Atlantic, but 

 does not seem to be common. It has been taken at 

 Faeroe, and on the coasts of Norway, Sweden, Denmark, 

 and Belsfium. Nothing seems to have been recorded of 

 its habits. 



The White-nosed Dolphin is a handsome species. 

 The following is Mr. Brightwell's description of the 

 Yarmouth specimen : — " The colour of the upper part 

 and sides was a very rich deep purple-black. The ex- 

 ternal cuticle was of a soft and silky texture, and so thin 

 and delicate that it was easily rubbed off. The nose and 

 a well-defined line along the upper jaw, and the whole 

 of the lower jaw and belly were of a cream colour, 

 varied in some parts by a chalky white, which contrasted 

 beautifully with the rich black of the body. The fins 

 and tail were of the same colour as the back." 



The teeth are small and are twenty-three to twenty-six 

 in number, in each side of either jaw. The vertebrae are 

 eighty-eight to ninety, and there are fifteen pairs of ribs. 

 The rostrum of the skull is as long as the brain-case and 

 is regularly tapered to the snout. 



The adult animal attains a length of eiuht or nine 

 feet. The following measurements are some of those 

 recorded by Mr. Brightwell : —
