Note: The Indian, or white, and the Javan rhinoceroses
({Rhinoceros Indicus} and {R. Sondaicus}) have incisor
and canine teeth, but only one horn, and the very thick
skin forms shieldlike folds. The two or three African
species belong to {Atelodus}, and have two horns, but
lack the dermal folds, and the incisor and canine
teeth. The two Malay, or East Indian, two-horned
species belong to {Ceratohinus}, in which incisor and
canine teeth are present. See {Borele}, and {Keitloa}.
{Rhinoceros auk} (Zo["o]l.), an auk of the North Pacific
({Cerorhina monocrata}) which has a deciduous horn on top
of the bill.
{Rhinoceros beetle} (Zo["o]l.), a very large beetle of the
genus {Dynastes}, having a horn on the head.
{Rhinoceros bird}. (Zo["o]l.)
(a) A large hornbill ({Buceros rhinoceros}), native of the
East Indies. It has a large hollow hornlike process on
the bill. Called also {rhinoceros hornbill}. See
{Hornbill}.
(b) An African beefeater ({Buphaga Africana}). It alights on
the back of the rhinoceros in search of parasitic
insects.
