CETACEA. 185 



D. tursio, Bonnaterre; vulg. le Souffleur ; Lacep. XV. f. 2. (Tlie 

 Great Dolphin). Snout short, broad, and depressed; from twenty- 

 one to twenty-four teeth throughout, conical, and often blunted. In- 

 dividuals have been seen fifteen feet in length, and it appears that 

 they are found in the Mediterranean as well as in the Ocean.* 



D. duhius, Cuv. Only thirty-six or thirty-seven teeth through- 

 out, but as fine and pointed as those of the Common Dolphin, which 

 it also resembles in its colours, 



D. frontalis, Duss. Very similar to the preceding, but coloured 

 somewhat differently, and has thirty-four teeth throughout. Dis- 

 covered by M. Dussumier, at the Cape de Verd Islands. 



D. frontatus, Cuv. But twenty-one teeth throughout, larger 

 than those of the preceding; the muzzle is also longer and more 

 compressed; its origin is not known. 



D. plumbeus, Dussum. The muzzle with the same compressed 

 form, but armed throughout with thirty-seven teeth. From Mala- 

 bar. -j- 



D. velox, Dussum. A somewhat longer muzzle, and forty-one 

 teeth throughout. From Ceylon. 



D. lomjirostris, Dussum. Surpasses even the Common Dolphin 



in the number of its teeth, having from fifty-five to sixty throughout. 



From the coast of Malabar, j; 



M. de Blainville separates from this first division of Dolphins, under 



the name of DELniiNORHYNCHUS, those species in which the snout, 



though long and slender, is not separated from the forehead by a decided 



furrow. One of them, 



D. micropterus, Cuv., was thrown upon the coast of France; it is 

 remarkable for its dorsal fin, which is also placed very far back. 

 It grows to the length of fifteen feet, and loses all its teeth at 

 an early age. § 



D. rostratus, . Cuv. A slender muzzle, and externally all of a 

 piece with the head; twenty-one teeth throughout. Its dorsal fin 

 is of the usual size.|| 



* The Whale or Capidolio of Belon, and the Orca, of the same author, which very 

 probably is that of the antients, belong also to the division of the Dolphins with 

 snouts, and are much larger than the above mentioned species; but their charactei's 

 are not sufficiently determined. The Dauphin feres of Bonnaterre is prpbable re- 

 ferrable to one of the two. 



t I suspect this D. plumbeus to be the same as the D, malaianus of MM. Lesson 

 and Gamier, Voy. de la Coq. pi. ix. f. 5. 



X We cannot, in this work, give a place to species which have been only seen at a 

 distance, and of which no part has been produced; we therefore mention, merely as 

 indications, the D. albigena, Quoy and Gaym., Voy. de Freyc. pi. xi. or D. super- 

 ciliosns. Lesson and Gam., Voy. de la Coq. pi. ix. f. 2. — The D. cruciger, Quoy and 

 Gaym. lb. f. 3 and 4, which is at least closely allied to the D. bivittatus, Less, and 

 Gam. f. 3. — The D. hmatus, Less, and Gam. f. 4. — Still less can we admit species 

 which have not even been figured. 



§ Blainville, Nouv. Bullet, des Sc. IV. p. 139, and Fr. Cuv. Mammif. under the 

 improper name of D. de Dak, which belongs to the Hyperoodoji. 



N.B. The D. rostratus of Shaw is the gangeticiis.
