The post-glenoid apophysis is represented by a very narrow ridge of bone, leaving only a slit-like cavity between it and the meatus. In Bovidee the temporals (e, fig. 327.) are partially hid by the overhanging frontals : they devclope short and strong zygomatic apophyses ; their bullas (e',fig. 327.) * F. Cuvier. are much narrowed, and their styloid pro- cesses are divided at the tip into several needle- shaped points. Bones of the face. — These are more nu- merous than those of the cranium, and we shall only notice the more important of them in detail. The nasals (7), which vary much in size, are long in the true Camels, a little spread out at the base and deeply notched in front, forming together three salient points : in the Llamas we find them very short and broad posteriorly. In Cervidas generally, the na- sals are much extended lengthwise and bifur- cate anteriorly (fig. 329.) : in the Muntjack (C. Muntjac) and in the Giraffe they are par- ticularly wide apart at the tipper or posterior border (Jig. 331.) ; and in the latter species they exhibit a gradual but marked rising towards the central eminence of the frontals (Jig. 328.). The naso-frontal suture in the genus Moschus is much denticulated. The nasals are very short in the Eland or Canna (A. orcas, Pallas), and in the Moose-deer (C. alces, Linn.) In OEgosceridae and Bo- viclae the bones of the nose are moderately long, and slightly convex above in the former (f,fig. 335.) ; in the latter family and in the Goats they are divided in front (f, fig. 327.); but in the Sheep they form together a single V-shaped process (l,fg. 332.)..
