The sing-sing and its relatives differ from the true waterbuck by the absence of the white elliptical ring on the rump

MOUNTAIN REEDBUCK.
One of a group of small antelopes still common in many parts of Africa.
In most species of duikers both sexes are horned, but in the case of the common duiker it is very exceptional to find a female with horns, and in all my experience I have only known of three such cases.
The Four-horned Antelope is the Indian representative of the African duikers, and is found along the foot of the Himalaya from the Punjab to Nepal, and in suitable localities throughout the peninsula of India. It frequents wooded hills, but avoids dense jungle. Like its nearest allies, the duikers, it is solitary in its habits, more than two of these antelopes seldom being seen together. The growth of four horns on the skull of this antelope and on certain breeds of domesticated sheep is a curious fact which has not roused as much comment as it deserves.
