252 DELPHINID^. 



This and the former species are very like D. Clymene, but are 

 broader and more depressed ; the intermaxillaries are more convex, 

 especially behind, and form a regular defined front edge to the 

 triangle, which is rough in front, and marked with oblique cross 

 grooves, while in B. Clymene the triangle is furnished with an 

 acute, raised margin on each side in front. 



A skull in Mus. Coll. Surgeons (Del^pMnus Belphis, Cat. Mus. Coll. 

 Surg. 161. n. 1117), with Qie palate convex, not grooved on the 

 side ; intermaxillary and vomer forming part of the palate ; teeth f^ ; 

 obtained from the Leverian Museum in 1806, may be another 

 variety.

Professor Nilsson thinks that D. Doris (Gray), D. pseudodelphis 

 (Schlegel, Abhandl. i. 22), and D. duhius (Cuvier, Mus. Paris), all 

 probably belong to this species. — SJcand. Fauna, i. 598. 



There is a skull from the Bay of Bengal in the Museum at Cal- 

 cutta, which Mr. Blyth has named Del/phinvs Eurynome, Gray (Blyth, 

 Cat. Mus. Asiat. Soc. Bengal, 90). Inhab. Bay of Bengal. 



Professor Burmeister informs me that he has a skull of this species, 

 in the Museum of Buenos Ayres, taken at the mouth of the Kio de 

 la Plata. I think it very probable that when the skulls from India, 

 the North Sea, and La Plata are compared, they may prove to be 

 distinct ; or there may be some confusion in the habitats.
