Plate XXII 



Characters. — Much smaller than the last, and of the approximate size of 

 the European roe, although more delicately and slenderly built. Antlers of 

 moderate size, with the lower or front prong of the main fork simple, and 

 the upper or posterior prong divided, and thus much the more complex, 

 the usual number of tines being three. Muzzle rather pointed ; ears 

 moderately large and filled with white hair ; tail moderately bushy. Hair 

 short and smooth, that of the middle of the back forming a whorl, and a 

 second whorl at the base of the neck, so that the fur of the withers is directed 

 forwards. 1 General colour of upper-parts and limbs light reddish brown, 

 with the individual hairs of the back light gray at the base, then darker 

 gray, followed by a ring of reddish brown, and the tip black ; face darker, 

 occasionally a black patch on the crown of the head, extending backwards 

 as a line to the level of the ears ; tarsal tuft, a patch at the base of the back 

 of the ears, a ring round the pedicles of antlers, another round each eye, the 

 lips, throat, chest, under-parts, front and inner side of thighs, of buttocks, and 

 of upper part of fore-legs, whitish ; flanks, outer side of limbs, and middle 

 of throat lighter than back ; tail dark blackish brown above and white 

 below. Upper canines generally present in the male. Very young fawns 

 lighter coloured, with a row of white spots on each side of the back, and a 

 second row running from the shoulder to the thigh. 



1 A similar peculiarity occurs in Cervus albirostris.
