Show here considered. There are several, however, by which it appears to be even more generalized than Palceotragus', namely, the narrow frontal region with its non-telescopic orbits, the anterior position of the latter, the smaller size of the horns, and the more brachyo-dont condition of the cheek-teeth (as compared with the large fossil species Samotherium boissieri). In one feature only, the large extension of the air-sinuses in the bony palate, the Okapi has conversely progressed further than the Giraffe. Palceotragus, finally, is more generalized than the Okapi-and, as a matter of course, more so than the Giraffe-in the non-fusion of the five tarsal bones into one, in the comparatively very slight extension of cranial air-sinuses, and in the anterior position of the horns. To sum up the state of our present knowledge of the Okapi.-In the species preserved at Tervueren (Okapia liebrechtsi) the male is provided with horns, but the same will presumably prove to be the case in the species represented in the Natural History Museum also. The mode of formation of the horns of the Okapi is the same as in the Giraffe. In the present state of our knowledge they are limited to the male alone of the former, so that the Okapi is in this respect on the same level as Palceotragus, the Giraffe having progressed farther. Besides the last-mentioned some further features which the Okapi shares with Palceotragus, and all of them of a more generalized character as compared with the Giraffe, have been added to those formerly pointed out. One feature has been added to those formerly mentioned, in which the Okapi occupies an intermediate position between Palceotragus and the Giraffe. And, lastly, we have been able to adduce some characters in which the Okapi appeal's to be even more generalized than Palceotragus. It is this last category especially which adds weight to the assumption that Africa was the original home of the Giraffidfe. 350 THE SECRETARY ON ADDITIONS TO THE MENAGERIE.
