"Rhinoceros Atelodus, with two well-marked species, peculiar to Africa. Incisors rudimentary or wanting, well-developed anterior and posterior horns in close contact; skin without definite permanent folds. R. bicornis, the common two-horned rhinoceros, is the smaller, and has a pointed prehensile lip. It ranges from Abyssinia to Cape Colony, but the progress of civilization and the attacks of sportsmen are rapidly reducing its numbers. Two varieties are said to exist, the square-mouthed, or white rhinoceros, has a square truncated lip, browses on grasses and frequents open country. It is the largest of the family, an adult male standing over six feet at the shoulder."—(Charles Leonard-Stuart, 1911)
