The teeth compressed, tre~cha~t and r?unded, fr~m twenty-two to twenty-five on each sule m 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 hke those of the common species. From the Cape seas. D. orca and D. gladiator; Buts-kopf and Schwerd-jisch of the Hollanders and Germans; Lacep. XV, 1, and not so well, V, 3. (The Grampus.)( 1) 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, pl. 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) D. globiceps, Cuv.(3) Ann. Mus. XIX, pl. i, fig. 2 and 3; D. 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 of grand poisson. Buts lcopf, or rather Boots kqpj, sig· nifies that its head is made like a long-boat. Scltwerd .fisch, Sword-fish, from lts dorsal fin. (2) The Epaulard ventru of Bonnaterre, Lacep. XV, 3, copied from IIunter, Phil. Trans. presents a. similar form; but Hunter's specimen was eighteen feet long, and ours never exceeds ten. The D. grisem, Ann. Mus., XlX, pl. i, f. 1, is merely a bad drawing of thisD· aries, lb. f. 4. The true aries of the ancients is the Grampus. . (3) It is the head of the D.globiceps deprived of its teeth, which is engraved In Bonnaterre, Cetol. pl. vi, f, 2: and in Lacep. pl. ix, f. 2, undel' the name of Cacludot swinewal; and in Camper, Cet. pl. xxxii, xxxiii and :xxxiv, under that of the Tooth/us Narwhal. 209 bELPHiNAPTERus, Lacep.
