skull is long, smooth and rounded, with imperfect zygomatic arches, no teeth of any sort, and, as in other ant-eating mammals, with the bony palate extending unusually far backwards towards the throat . The lower jaw consists of a pair of thin rod-like bones, welded to each other at the

Asiatic pangolins are characterized by having the central series of body-scales continued to the extreme end of the tail, by having many isolated hairs growing between the scales of the back, and by their small external ears . They all have a small naked spot beneath the tip of the tail, which is said to be of service as an

African species have the central series of scales suddenly interrupted and breaking into two at a point about 2 or 3 in. from the tip of the tail; they have no hair between the scales, and no external ears . The following four species belong to this

forty-six caudal vertebrae, nearly the largest number known among Mammals; the white-bellied pangolin (M. tricuspis), closely allied to the last, but with longer three-lobed scales, and white belly hairs; and the short-tailed and giant pangolins (M. temmincki and gigantea), both of which have the tail covered entirely with scales . Those species with a naked patch on the under side of the tail can climb trees . The four species of the second group are found in West Africa, although some extend into south and eastern e uatorial Africa . (O . T.; R .
