DOLPHINS 269 



from the Malabar coast. Its external characters have 

 been described by M. Dussumier, who observes that 

 the young have much more white about them than 

 the adults a reversal of the conditions of colour 

 which characterise, for example, the Beluga. This 

 species is said to be slower in its movements than 

 many dolphins. It reaches eight feet in length. 



Solatia gadamu, Owen,* is in colour dark plum- 

 beous grey, below pinkish ashy grey, with a few 

 darker blotches. Teeth, 26. Rostrum not so long 

 as in last two species. 



This species, known only from a sketch of its 

 shape and colour, and from the skull, is named by the 

 fishermen of Vizagapatam " Gadamu," whence its 

 specific name. 



Also described by Owen is Sotalia tentiginosa, of 

 a bluish cinereous colour, freckled with dark brown. 

 Fins smaller than in S. gadamu. Teeth, 33-34. 



This species, from the same locality as the last, 

 is regarded by Flower as doubtfully distinct. True, 

 however, affirms the correctness of Sir R. Owen in 

 giving it a separate name. And we shall follow him. 

 Dr. Blanford would refer this and the last species 

 (under the name of S. perniger\} to the genus Steno.
