Pronghorn (Antilocapra americana), an aberrant antelope, about the size of a fallow-deer, from the prairie-lands of North America. Both sexes bear true horns, which are shed annually. Those of the male are about a foot long, curved backwards at the tip, with a branch directed forwards rather more than half-way from the base. Those of the female are very much smaller.
