251 CLASS MAMMALIA. 



explicit, and possibly not altogether correct. We are, how- 

 ever, inclined to believe that there are two species of Tetra- 

 ceri, differing in the characters of the horns, and in some 

 other trifling particulars, as shall be noticed in the sequel. 

 The name of the group is derived from the generic denomi- 

 nation which Dr. Leach first bestowed upon the Four-horned 

 .Antelopes. 



The Chickara. (A. Chickara.) We cannot give a more 

 satisfactory description of this animal than by repeating 

 the excellent account furnished by General Hardwicke, 

 in the Linnaan Transactions, Vol. xiv. " This spe- 

 cies of Antelope," he says, " seems hitherto to have 

 escaped any particular description of the naturalist ; and 

 this circumstance is the more remarkable, as the animal is 

 not scarce in India. It inhabits the forests and hilly tracts 

 along the western provinces of Bengal, Bahar, and Orissa, 

 and is known by the name of Chickara. It is an extremely 

 wild and agile creature, and only to be tamed when taken 

 young. In size this species is something less than the 

 Harnessed Antelope (A. Scripta) ; it is in height, from the 

 foot to the top of the shoulder, twenty inches and a half; 

 and in length, from the nose to the root of the tail, thirty- 

 three inches, or two feet nine inches ; and the tail is five 

 inches more. The superior, or common horns, are black, 

 subulate, rounded, without annulations, smooth, and erect, 

 slightly inclined forward, and a little diverging; their 

 length three inches ; space between them at the base one 

 inch eight-tenths ; the greatest thickness at the base is two 

 inches in circumference, and gradually tapering to a point 

 one-tenth of an inch in diameter. In front of the common 

 horns (one inch four-tenths), in the middle of the forehead, 

 and between the eyes, rises a very short pair of spurious 

 horns, erect, stumpy, smooth, cylindrical, three-quarters of 

 an inch in length, one inch and a half in circumference at 

 base, and suddenly tapering to a point ; they are apart at
