In (Egosceridae (g,fig- 335.) and Cer- pardalis they exhibit a slight concavity at the vidae, for the most part, the ascending rarai in- upper margin. In this last, named genus the in- cline at a very oblique angle, and in Camelo- termaxillary bones are very long and extremely Front view of the skull of an Ox, with the right horny sheath detached from the core. (From Lond.' Coll. Surg. Museum.) attenuated at the tip (fig. 328.) ; in Bovidas, on the other hand, they are of diminished length (g, Jig. 327.), straight, of great thick- ness and broad in front, giving to the muzzle an aspect characteristic of the group (],Jig. 333.). The incisive openings are elongated, capacious, and widely separated in the Giraffe (Jig. 328.), they are still more so in the Stags (fig, 329) and Antelopes (fig. 342.) ; and in (Egosceridae and Bovidae they form enormous clefts, especially in the latter {fig. ). Several genera have a small free space be- tween the converging points of the inter- maxillaries; and this is particularly noticeable in the Giraffe (fig. 328). The bones in question are of great length in the Eland or Cape Elk, and in the Moose-deer. The maxillaries (2) usually carry six molars and premolars on either side ; excep- tions, however, occur in the Camelidas where one of the premolars is absent, and in this family, as also in the aberrant genus Moschus and in the male Cervus Muntjac, canines are developed (a, Jig. 331.). In all ruminants they send processes of greater or less extent to the inner and under part of the orbit, in the situation where these bones lie partly concealed by the jugular or malar bone. As regards the bones themselves there are few other peculiarities worthy of notice ; but we may remark, in passing, that in the Giraffe the maxillaries project more than two inches beyond the tips of the nasals.
