Striped Dolphin 



Lagenorhynchus acutus (Gray) 



Length. 8 feet. 



Description. Beak very short, a mere rim with a depression 

 between it and the forehead on each side. Colour black on 

 back, rest of body gray, sides with white and yellowish 

 patches; a narrrow black stripe from the base of the tail half- 

 way to the middle of the body; eye surrounded with black

Harbour Porpoise 



Ptiocana phocana (Linnaeus) 



Length. 5 feet. 



Description. Head rounded in front, no beak or snout. Fin of 

 the back more triangular than in the dolphins. Colour dark 

 slate or blackish, shading gradually to white on the belly, 

 sides somewhat tinged with pink or yellowish, and a dark 

 band from the lower jaw half way to the flipper. Teeth 26 

 in each jaw. 



Range. North Atlantic south to New Jersey; also on coasts of 

 Europe and in the Pacific. 



As the bottle-nose (Tursiops tursio) is the commonest of the 

 dolphins on our coast, this is the best known of the round-headed 

 or porpoise group. It is apparently more common on European 

 coasts than with us and, being more northern in its range, is 

 not so familiar as the common bottle-nose to our sea-shore 

 visitors. 



The five species which follow are all allied to the harbour 

 porpoise, but have striking peculiarities which have earned for 

 them distinctive popular names.
