The osseous protuberances support- ing the horns, of which we shall speak more particularly when describing the latter in detail, take their origin in most cases from the frontal bones. In the Giraffe the slight eminences analogous to the osseous cores are partly formed by the parietal bone, the coronal suture passing directly through the centre from side to side (fig. 328.) ; the an- Fig. 328. Front view of the skull of a Giraffe. (From a spe- cimen in Lond. Coll. Surg. Museum.) terior or central eminence, situated imme- diately behind the nasals, anil in part formed by them, differs in no respect, save as regards its position, from the other two, the elevation in all instances being produced by the expan- sion of the cranial sinuses beneath. There is a single large supra-orbital canal, having its superior outlet midway between the upper border of the orbit and the central frontal eminence (fig. 328.). In Cervidas generally, the canal opens at the upper surface by a longitudinal furrow (fig. 329.), but this is more particularly marked in Bovidae ( fig. 333.). In regard to the cranial sutures in Cervidas, M. F. Cuvier observes that ' all those por- tions, such as the second half of the frontal, the greater part of the coronal, and the occi- pital or lambdoidal, which surround the base of the core, exhibit an excessive multiplication of interlineations, because the weight of the horns and the shocks to which the parts are exposed require that the bones should be firmly connected ' (/z0r. 329). The sphenoid (Is?) articulates, except in Bovidae. with all the cranial bones; but its orbitar wi
