208 MAMMALIA. 



D. phocsenOi L. j Lacep. XIII, f. 2. (The Common Por- 

 poise.) The teeth compressed, trenchant and rounded, from 

 twenty-two to twenty-five on each side in each jaw; blackish 

 above, white beneath. It is the smallest of the Cetacea, seldom 

 exceeding four or five feet in length; very common in all our 

 seas, where it is found in large troops. 



D. capensis, Dussum. (The Cape Porpoise.) Similar to the 

 preceding, but has twenty-eight teeth throughout, cylindrical, 

 slightly pointed, and not compressed like those of the common 

 species. From the Cape seas. 



B. orca and D. gladiator; Bicts-kopf SLnd Schwerd-fisch of the 

 Hollanders and Germans; Lacep. XV, 1, and not so well, V, 3. 

 (The Grampus. )(l) Teeth, thick, conical and slightly hooked, 

 eleven every where; the posterior ones flattened transversely; 

 the body black above, white underneath ; a white spot on the 

 eye in the form of a crescent; the dorsal fin elevated and pointed. 

 It is the largest of the Dolphins, being frequently found from 

 twenty to twenty-five feet in length, and is the most relentless 

 enemy of the Whale. They attack it in troops and torment it 

 until it opens its mouth, when they devour the tongue. 



D. aries, Risso; Ann. Mus. XIX, pi. i, fig. 4. A smaller spe- 

 cies sometimes seen upon the coast of France, which soon loses 

 the upper teeth and preserves only a few of the lower ones. 

 Its dorsal fin is lower and further back than that of the Gram- 

 pus.(2) 



B. globiceps, Cuv.(3) Ann. Mus. XIX, pi. i, fig. 2 and 3; Z>. 

 deductor, Scoresby. (The Round-headed Grampus.) Top of 

 the head so arched as to be globular; long, pointed, pectoral 

 fins; it is more than twenty feet in length; black, with a white 

 stripe from the throat to the anus. It lives in troops of several 

 hundreds, led by the old males, and is sometimes thrown upon 

 the coasts of Europe. It has from nine to thirteen teeth through- 

 out, but loses them all with age. 



(1) Grampus, a corruption oi grand poisson. Buts kopf, or rather Boots kopf, sijj- 

 nifies that its head is made like a long-boat. Schwerd Jisch, Sword-fish, from its 

 dorsal fin. 



(2) The Epaulard ventru of Bonnaterre, Lacep. XV, 3, copied from Hunter, 

 Phil. Trans, presents a similar form; but Hunter's specimen was eighteen feet 

 long, and ours never exceeds ten. 



The D. griseus, Ann. Mus., XIX, pi. i, f. 1, is merely a bad drawing of this D. 

 aries, lb. f. 4. The true aries of the ancients is the Grampus. 



(3) It is the head of the D. globiccps deprived of its teeth, which is engraved in 

 Bonnatcne, Cetol. pi. vi, f. 2: and in Lacep. pi. ix, f. 2, under the name of 

 Cachalot sivinewal,- and in Camper, Get. pi. xxxii, xxxiii and xxxiv, under that of 

 tlie Toothless Narwhal.
