Catalogue of the Whales and Dolphins (Cetacea) inhabiting or 

 incidentally visiting the Seas surrounding the British Islands, 

 By Dr. J. E. Gray, F.R.S., &c. 



(Continued from Zool. S. S. 3364.) 



Section II. Denticete. 



Teeth well developed in one or both jaws, sometimes deciduous. 

 Palate without baleen. Head large or moderate, compressed. 

 Tympanic bones two, dissimilar, separate, becoming united, 

 sunk in a cavity in the base of the skull. Gullet large. 



The geographical distribution of the toothed whales or dolphins 

 is rather uncertain, from want of observations, and the evident 

 gradual extermination of the species by the increase of navigation 

 incident to the extension of commerce, and especially the use of 

 steamboats, which disturb the breeding of these animals. 



I believe that the porpoise {Phoccena communis) is the only 

 species that is a permanent resident here. 



The Goose Whale {Hyperoodon bulzkopf) often breeds in the 

 country, but it is doubtful if it does not become gravid from the 

 North Seas. 



The Toothed Whales and Dolphins may be divided into three 

 series : — 



I. Those that live and breed in the arctic and the northern part 

 of the Atlantic, some specimens of which proceed southwards after 

 the herrings and other fish. They sometimes have their young on 

 the British coasts, but I suspect that only a few, if any, of the 

 specimens which come as far south as the British Channel ever 

 escape being destroyed and find their way back to the Arctic 

 Sea, as — 



1. The Goose Whale {Hyperoodon hutzkopf). A frequent visitor. 



2. The Pilot Whale {Globiocephalus Svineval), which comes in 

 large "schools" to the North of Scotland, and smaller groups or 

 single individuals further south. 



3. The Black Fish {Physeter tursio) is described from a speci- 

 men long ago taken on the coast of Scotland. 



4. The Euphrosyne {Clymenia Euphrosyne) and (5) the White- 

 beaked Bottle-nose (Lagenorhynchus albirostris) inhabit the North
