276 A BOOK OF -WHALES 



Delphinus truncatus, Montagu ; D. metis, Gray ; 

 D. cymodice, Id., ; D. eurynome. Id., are apparently 

 synonyms. 



Tursiops catalania, Gray,* is in size small (6 feet 

 9 inches). The colour is as in T. tursio, but the 

 sides are covered with blotches of darker colour. 

 Beak relatively longer than in T. tiirsio. This species, 

 as already said, is admitted by both Sir William 

 Flower and by Mr. True. It is a native of the 

 north-east coast of Australia. 



The skull only (as far as the skeleton is concerned) 

 is known ; but the collector, Mr. John MacGillivray, 

 sent home to Dr. Gray careful measurements and a 

 description of the colour of two specimens which 

 he obtained at localities not far apart. 



Tursiops abusalam, Riippell,f is dark green above ; 

 under surface white with dark spots. Teeth, 26. 

 Vertebrae: D. 12; L. 16; C. 26 = 61. Beak longer 

 than in T. tursio. 



This dolphin, from the Red Sea, does not differ 

 widely from Tiirsiops catalania, and may very possibly 

 be identical with it. Yet the green colour seems to 

 be characteristic and, as dolphins go, unusual. The 

 number of vertebrae and ribs, as a character, must 

 be handled with caution, for Mr. True records an un- 

 doubted T. tursio with but twelve ribs and sixty-one 

 vertebrae.
