The legs are long, thin, and delicate, being about the size of a lead pencil. In the genus Tragulus the pairs of metacarpal and metatarsal bones in the limbs are united into a single unit, known as a cannon bone. In Hyemoschus a cannon bone is not formed until old age. Each foot has four well-developed digits, though the lateral digits of Hyemoschus do not touch the ground when the animal stands. The stomach is three-chambered and ruminating.
Females have four mammae.
There are no horns or antlers. The lower canines look like incisors. The molars bear crescentic ridges of enamel on their crowns. All the cheek teeth are arranged in a continuous series. The Johns Hopkins University Press.
