The Earl of Derby, in answer to some queries, observes : "As to the Nagor of Ogilby, it has no tuft 
on the knees, nor has it the mark you have traced on the paper given to John Thompson. The inside of 
the fore limbs is pure white, and the hair so long as to give a sort of fringe to the edge of the bone. I 
could not perceive any mark between the nostrils, as you have marked on your paper, but the whole space 
between them and around appeared to me naked and black ; but I may not be quite accurate, as he vi'^as 
much excited, and several men had some difficulty in holding him. The Nagor has on the outside front of 
the fore-arm a stripe of black for some inches above the knee, and also a good deal of the same colour 
upwards from the fetlock, from two inches below the hough down to the foot. It has also some of the 
same colour on the hind legs, in front, but I did not notice particularly how much ; but behind, it has only 
the ring above the fetlock ; whence I imagine you gave it the name of A, anmilvpesr

This species varies much in the tint of the colouring, and in the length of the hair in the different 
seasons. In summer they are covered with very short, closely pressed fur, letting the skin be seen between 
the hairs. In the cold weather, and in England, the fur is longer and more abundant. The hair of the 
chin atid neck is long and rigid in all seasons, and even in the young animals. The tail of the adult speci- 
men is cylindrical and nearly bald, ending in a tuft of black hair; in the young specimens, especially in the 
winter fur, the base of the tail is fringed with hair on each side. The male is much brighter coloured, and 
the chest and belly are nearly black like the legs. The hinder parts of the rump of the young animals are 
greyish white ; in the older specimens it becomes pure white and broader in extent. 
This animal is called Sing-Sing by all the negroes. They do not think their flocks of cattle will be 
healthy or fruitful unless they have one of the Sing-Sings accompanying them, as some persons think a 
Goat necessary to be in a stable in England. The English on the Gambia call it the Jackass Deer from its 
appearance, and it is called Koba and Kassimause by the negroes at Macarthy's Island. Its flesh is very 
strong, unpleasant and scarcely palatable. 
As far as I could judge by my recollection and description, the adult specimen at Knowsley, the young 
male and adult female in the British Museum, the male and female at Frankfort, and the adult male in the 
Paris menageries are the same species. 
Buffon figured (Hist. Nat. 210, 267. xii. t. 32. f. 2) under the name of Koba a pair of horns which were 
in the Library of St. Victor at Paris. He described them as larger and more curved above than those of 
iki^Kob, eighteen inches long and five inches in circumference at the base, and he refers them to an animal 
which Adanson says is called Koba in Senegal, and the Great Brown Cow by the French colonists. Pallas 
refers these horns to A. Pygargus, and the figures and description agree in many particulars with the
