absence of the large flattened, fibrous, and downwardly 
curving yellow horns, which almost meet in the middle 
line of the forehead of the adult bull, renders the aspect 
of the head of the calf very different. In other respects, 
however, the calves are very like the full-grown animals 
in general appearance, showing the same long, straight, 
and rather coarse hair, the conspicuous light-coloured 
“saddle” on the back, the white “stockings,” the woolly 
triangular ears, the broad and almost completely hairy 
muzzle, and the entire burying of the rudimentary tail in 
the long hair of the hindquarters. Owing, however, to 
the inferior length of the hair on the flanks, more of the 
legs is exhibited in the young than in the adult; and 
this enables the peculiarly heavy and massive form of the 
pasterns and feet to be better seen. Nothing was more 
curious about the calves at Woburn Abbey than their 
movements, which recalled those of a Polar bear more 
than those of an ox or a sheep, the hocks being turned 
outwards in an altogether peculiar and distinctive manner. 
If this strange gait is also characteristic of the adult, it is 
probably adapted for progression on glaciers and other 
ice-coated surfaces ; firmness of foothold being secured by 
the presence of a considerable amount of hair on the 
under-surface of the foot. 
But there is one respect in which the Clavering Island 
calves differed from the adult specimens exhibited at the 
time of their arrival in the British Museum, as well as from 
the description then given of the species. This is the 
presence of a large patch of white hair on the forehead, 
as well as of an ill-defined white streak down each side of 
the face, and some scattered white hairs in the middle line 
between the muzzle and the eyes. 
As these differences have been found to be constant,
