A gland and tuft are present on the skin of the outer side of the upper part of the hind cannon-bone; but, unlike American deer, there is no gland on the inner side of the hock.
This is one of the few deer in which there are glands neither on the hock nor on the skin covering the cannon-bone.
Reduction and final loss of outer pair of digits (second and fifth), with coalescence of the metacarpal and metatarsal bones of the two middle digits to form a cannon-bone.
In the Sheep and the Camel the long compound bone, supporting the two main (or only) toes is the cannon-bone.
The most interesting genera are, however, the Upper Oligocene and Lower Miocene Gelocus and Prodremotherium, which have perfectly selenodont teeth, and the third and fourth metacarpal and metatarsal bones respectively fused into an imperfect cannon-bone, with the reduction of the lateral metacarpals and metatarsals to mere remnants of their upper and lower extremities.
