development of the horns of the Gnu,! from which it appears that 
in very young individuals the horns are straight and divergent, 
situated some distance below the vertex of the head, and separated 
by a wide hairy interval. These young horns form the straight

of the horns forms a helmet-like mass on the forehead which 
completely obliterates the hairy frontal space of the young.

Indian Antelopes, with simple horns present only in the males, a 
more or less elongated suborbital gland, a lachrymal depression 
in the skull, and square-crowned upper molars (Fig. 140). Lateral 
hoofs well developed.
