 Tursiops aduucus, Gervais, Mamm. 323. 



Inhab. Red Sea. 



Only known from Dr. Riippell's description and figure. It has 

 been said to be the same as D. Tursio, but it appears to be different. 



Delpliinus adimeus, Hempr. & Ehrenb. Sym. Phys. ii. (Beak de- 

 pressed, elongate ; teeth -§4, conical, strong. Inhab. Island of Bel- 

 hosse), is perhaps the same as the former. 



8. Tursio Eurynome. The Eurynome. 



Skull roundish ; nose thick, broad, rounded above ; intermaxil- 

 laries rather convex, one-half as wide as maxillaries ; nose one-third 

 longer than the length of the head (or contained four times and 

 one-seventh in the entire length), twice and one-third the width at 

 the notch ; hinder edge of blower largely tubercular ; teeth |4, 

 moderate, cyKndrical, rather curved, acute.

 one-fourth longer than the length of the head, slenderer, and more 

 rounded, and the teeth smaller.
