BRITISH MAMMALS 



by a band of grey. Above the line and extending backwards in a 

 rapidly widening triangle which includes the black eye patch, the skin 

 is lead coloured. A narrow black line extending backwards to the 

 ear and from the level of the posterior cankus, forming a conspicuous 

 relief to the lead-coloured area." 



The colour of the upper parts of the body is black, broken up by 

 a band of white on the sides which blends into another patch of 

 pale brownish buff extending towards the tail. The throat and belly 

 are white with black markings surrounding the vent. The flippers are 

 black, with a stripe of the same colour extending from their base to 

 the corner of the mouth. 



The White-sided Dolphin inhabits the North Atlantic ; ranging from 

 as far north as Greenland to the British Islands. It is also found 

 along the eastern shores of the United States. 



Dr. Gray first described the species from a skull found in the 

 Orkneys, and an adult female was also obtained there in May 1835. 

 A party of about twenty were taken together in Scapa Bay, Kirkwall, 

 on May 21, 1858. One has been recorded from Ardrishaig and another 

 at Dunrobin stranded in April 1906. 



A few have been taken in Ireland, one as late as 191 6 on the 

 coast of Mayo. Like other Dolphins, this species moves about in 

 * schools,' frequently leaping clear of the water as it sports among the 

 waves along with its companions.
