(From a specimen in Lond. Coll. Surg. Museum.) the orbit of the opposite side ; a peculiarity not confined to the animals under con- sideration, being more marked in certain of the llodentia and in birds. In Boviclae the temporal wing of the sphenoid, which is of comparatively large size and much curved backward, does not reach the parietal bone as in the other ruminants ; and it is further distinguished by a sharp pointed ridge de- veloped from its anterior margin, which in the preceding genera is only feebly indicated, though tolerably prominent in the Giraffe. The anterior wing extends horizontally for- ward and is convex on its orbitar surface (d,Jig. 327.). Part of the body of the pos- terior sphenoid forms, in conjunction with the anterior third of the basi-occipital, two projecting elevations, which are separated from each other by a deep groove : these also appear in the Goats, where they are less marked. In both families the spheno-palatinc and the spheno-orbitar foramina are capacious; but in CEgosceridae the latter openings are somewhat compressed. The os cthinoidcx has the same relations as usual, its cells being greatly developed in the Giraffe. The temporal bone (10), as in other mam- malia, consists of three segments. In Camc- lidse the zygomatic arches form, in conjunction with the sunken temples and strongly pointed occipito-parietal crests, a striking feature, which imparts to the cranium of this family a carnivorous type of structure. This mor- phological peculiarity is chiefly noticeable in the Camels properly so called ; and in them the glenoid cavity is very deep, being sup- ported in front and behind by prominent apophy
