40 MAMMALIA CETACEA. [MANATUS. 



up by the tusks : body covered with long stiff bristles, intermixed at the roots with 

 a soft woolly hair ; the longest and strongest bristles on the back. General colour 

 dusky gray DESM. 



*Var. ft. domestica. (Domestic Hog.) In this variety the ears are longer and 

 more or less pendulous ; the bristles more thinly scattered, and of one sort ; the 

 tusks comparatively short ; the tail more or less twisted ; the size and colour very 

 variable. 



Formerly abundant in a wild state throughout the country. Continued to inhabit 

 the forests about London so late as the reign of Henry the Second, but it is not 

 exactly known how soon after that period they were extirpated. In the domestic 

 state the Sow goes with young about four months, and is very prolific, producing 

 sometimes as many as twenty at a litter. Food extremely various.

Two instances at least are on record in which specimens of the Her- 

 bivorous Cetacea have been observed in the British seas, but there is no 

 satisfactory evidence by which the species can be determined, or even 

 the genus, to which they belonged*. In the Elements of Nat. Hist, by 

 Mr Stewart, mention is made (vol. i. p. 125.) of the carcase of one of 

 these animals which was thrown ashore near Leith ; and in the Edinb. 

 New Philos. Jonrn. as quoted above, there will be found some account 

 of another individual, which occurred a few years ago off the Shetland 

 Islands. See also Dr Fleming's Brit. An. p. 30. 



GEN. 27. DELPHINUS, Linn. 



(1. DELPHINUS, Cue.) 



63. D. Delphis, Linn. (Common Dolphin.) Jaws mo- 

 derately produced ; nearly of equal length : teeth more than 

 forty on each side above and below ; slender, slightly bent, 

 pointed.

DESCRIPT. Body slender, thickest in the middle, gradually tapering 

 towards the head and tail : muzzle or beak, measured from the forehead, 

 equalling in length the rest of the head ; much depressed, narrow, and 



* On this account I have introduced, in the Synoptic Arrangement of Genera, the characters of 

 both Manatus and Stellerus Cuv., which are perhaps equally likely to occur in the British seas. 

 At any rate they will prove useful in determining the true genus of any of these animals which 

 may be met with hereafter.
