16 MAMMALIA FER.E. [PHOCA. 



Common on many parts of the coast, but prefers rocky shores. Swims 

 and dives readily. Preys on fish, which it devours under the water. 



Breeds about Midsummer, and produces two young Obs. The Pied 



Seal of Pennant is probably only a variety of this species. 



16. P. barbata, Mull. (Great Seal.) Fur blackish: 

 middle toes on the forefeet longer than the lateral ones.

 Seal, Penn. Brit. Zool. vol. i. p. 136. Don. Brit. Quad. pi. 11. 



DIMENS. Entire length from ten to twelve feet. 



DESCRIPT. Teeth as in the last species : head somewhat elongated : 

 muzzle broad : upper lip rounded, fleshy, divided into two lobes by a deep 

 furrow ; each lobe furnished with numerous strong white bristles, semi- 

 transparent, and curled at the ends : eyes large; irides dark hazel: auri- 

 cular apertures larger than in the last species : fore feet rather long, with 

 the middle toe more developed than the lateral ones ; claws of these black, 

 horny, and curved ; those of the hind feet long and straight : body elon- 

 gated ; when young, clothed with a long woolly fur, which after the space 

 of fourteen or fifteen days is cast and superseded by a new covering of 

 close short hair* : general colour dusky gray, in very old individuals 

 black. 



Inhabits the coast of Scotland, and (according to Selby) the Farn 

 Islands, but is much less common than the last species. Breeds in 

 November.
