y _Poiana richardsoni_, a small species with a spotted genet-like coat, and also with a narrow naked stripe on the under surface of the metatarsus, as in genets. Here may be placed the two African spotted palm-civets of the genus _Nandinia_, namely _N. binotata_ from the west and _N. gerrardi_ from the east forest-region. In common with the true palm-civets, they have a dentition numerically identical with that of _Viverra_ and _Genetta_, but the cusps of the hinder premolars and molars are much less sharp and pointed. They are peculiar in that the wall of the inner chamber of the auditory bulla never ossifies, while the paroccipital process is not flattened out and spread over the bulla. In this respect they resemble the Miocene European genus _Amphictis_, as they do in the form of their teeth, so that they may be regarded as nearly related to the ancestral _Viverridae_, and forming in some degree a connecting link between the present and the next subfamily. _Nandinia_ is also peculiar in possessing a kind of rudimentary marsupial pouch. Apparently _Eupleres goudoti_, of Madagascar, which has been generally classed in the _Herpestinae_, is a nearly related animal, characterized by the reduction of its dentition, due to insectivorous habits (fig. 3); the canines being small, the anterior premolars canine-like, and the hinder premolars molariform. It is a uniformly-coloured creature of medium size. [Illustration: FIG. 3.--Skull of _Eupleres goudoti_.] The palm-civets, or paradoxures, constituting the Asiatic genus _Paradoxurus_, have, as already stated, the following dental formula, viz. i. 3/3, c. 1/1, p. 4/4, m. 2/2, total 40; the cusps of the molars being low and blunted, and these teeth in the upper jaw much broader than in the civets. The head is pointed in front, with small rounded ears; the limbs are of medium length, with the soles of the feet almost completely naked, and fully retractile claws; while the long tail is not prehensile and clothed with hair of moderate length. Spots are the chief type of marking. The vertebrae number C. 7, D. 13, L. 7, S. 3, Ca. 29-36. Numerous relatively large species ranging from India to Borneo, Sumatra and Celebes, with one in Tibet, represent the genus. Nearly allied are _Arctogale leucotis_, with a wide distribution, and _A. trivirgata_, of Java, both longitudinally striped species, with small and sli
