rhinoceroittc, < L. rhinoceros, < Gr. ptvoKcpuf 
(-Kepor-), a rhinoceros, lit. ' nose-horned,' < pif 
(piv-), the nose, + nepaf, a horn.] 1. A large 
pachydermatous perissodactyl mammal with 
a horn on the nose ; any member of the genus 
Rhinoceros or family Rltinocerotidfe. There are 
several living as well as many fossil species. They are 
huge ungainly quadrupeds, having an extremely thick 
and tough or hard skin, thrown into various buckler-like 
plates and folds. The legs are short, stout, and clumsy, 
with odd-toed feet, whose three digits are incased in 
separate hoofs. The tail is short; the ears are high and 
rather large; the head is very large and unshapely, sup- 
ported upon a thick stocky neck ; the muzzle is blunt, and 
the upper lip freely movable. The head is especially 
long in the nasal region, and there are usually one or two 
massive upright horns, without any bony core, the sub- 
stance of the horn being epidermal only. When two 
horns are present they are one behind the other in the 
median line, and the hinder one rests over the frontal 
bone, the front one being in any case borne upon the 
nasal bones. Rhinoceroses live mainly in marshy places, 
in thick or rank vegetation, and subsist entirely upon 
vegetable food. The living species are now confined to the 
warmer parts of Africa and Asia, and are hairless or nearly 
so ; but these animals formerly had a much more extensive 
range, not only in the Old World, but also in America. 
The best-known of the extinct species is R. tichnrhinus, 
the woolly rhinoceros, which formerly ranged over Europe, 
including the British Isles. Of the existing one-horned 
Rhinocerovlieetle (I\vn<utes

One-homed Rhinoceros (Khinoeeras unicomis}. 
species are the Indian rhinoceros, R. indicus or R. m'- 
cornis, which inhabits the warmer parts of Asia, attains a 
height of 5 feet, and has the horn short and stout ; the 
Javan rhinoceros, R. sondaicus, or R. javanus, distinct 
from the Indian species, inhabiting Java, the Malay pen- 
insula, etc.; the hairy-eared rhinoceros, /,'. lasiotin; and 
the African kobaoba, R. siixm. The two-honied species 
include the Sumatran or Malaccan rhinoceros, li. suma- 
tremis ; and the African keitloa, R. keitloa or bicornis. See

male sex a large up-curved horn on the head, 
resembling somewhat the horn of the rhinoce- 
ros, as well as a more 
or less developed pro- 
thoracic horn. The com- 
mon rhinoceros-beetle of the 
United States, Dynatta U- 
'//"-, the largest of the North 
American beetles, has two 
large horns directed forward, 
one arising from the thorax 
and one from the head, in the 
male beetle only. The gen- 
eral color is greenish-gray 
with black markings, and be- 
tween this form and a uni- 
form brown there are many 
gradations. The larva feeds 
in decaying stumps and logs. 
Both beetle and larva have 
a peculiarly disagreeable odor, which, when they are pres- 
ent in any number, becomes insupportable. It. herctues of 
South America is another rhinoceros-beetle, specifically 
called the Hercules-beetle, whose prothoracic horn is im- 
mensely long. See also cut under Hercules-beetle.

Rhihocerotidae (ri-nos-e-rot'i-de), n.pl. [NL.., 
< Rhinoceros (-ot-) + -?.] A family of peris- 
sodactyl ungulate mammals, for the most part 
extinct, typified by the genus Rhinoceros. The 
nasal region is expanded or thrown backward, the su- 
pramaxillary bones forming a considerable part of the 
border of the anterior nares. and the nasal bones being 
contracted forward or atrophied. The neck is compara- 
tively abbreviated. The molar crowns are traversed by 
continuous ridges, more or less well denned, the upper 
ones having a continuous outer wall without complete 
transverse crests ; the incisors are reduced in number or 
entirely suppressed. The basioccipital is comparatively 
broad behind and narrow forward ; the tympanic and 
periotic bones are ankylosed and wedged in between the 
squamosal, exoccipital. and other contiguous bones. The 
only living genus is Rhinoceros, from which Rhinaster and 
Atelodus are sometimes separated. There are several ex- 
tinct genera, as Ccelodonta, Acerotherium, Jtadacth< -rii'/ii. 
and Ht/racodon. The family is one of only three which 
now represent the once numerous and diversified sub- 
order Pertisodactyla. the other two being the Tapiridir or 
tapirs and the Equidte or horses. See cuts under Perweo- 
dactitla and rhinoceros.
