The common Malay deer is widely distributed, Cervus muntjac less so.
In the Asiatic muntjac deer we find a pair of skin-covered horns, or " pedicles," corresponding to the paired horns of the giraffe, although welded to the skull.
Some of the more northern American deer, such as the wapiti, reindeer and elk (moose), are closely allied to Old World species; but there is also a group of exclusively American deer (Mazama) - the only one found in Central and South America - the members of which are unlike any living Old World deer; and these must be regarded as having reached the western hemisphere at an earlier date than the wapiti, reindeer and elk (see Deer, Elk, Fallow-Deer, Muntjac, Musk-Deer, Pre David'S Deer, Reindeer, Roebuck, Water-Deer, &c.).
Other species include the hog deer (C. porcinus), the barking deer or muntjac (Cervulus muntjac), and the chevrotain or mouse deer (Tragulus meminna).
For the small eastern deer, respectively known as muntjacs (Cervulus) and tufted muntjacs or tufted deer (Elaphodus), see Muntjac; while under Water-Deer will be found a notice of the Chinese representative of the genus Hydrela phus (or Hydropoles).
