“ When running, they arch their backs and scurry away in a series of short leaps. In captivity as many as three have been produced at a birth. This is one of the few deer in which there are glands neither on the hock nor on the skin covering the cannon-bone. These glands probably enable deer to ascertain the whereabouts of their feUows by the scent they leave on the ground and herbage. The sub-aquatic habits of the present species probably render such a function impossible, hence the absence of the glands. The tail is represented by a mere stump. ”
