the moose, in the simpler maxillary suture and shorter anterior 

 process. The orbit is somewhat smaller than in the moose, and 

 more nearly circular, the vertical diameter being greater in the 

 latter, while the antero-posterior diameter is about the same in 

 both. While the frontal rim of the orbit is more projecting than 

 in Alces and the whole orbit is deeper, the jugal rim is less dis- 

 tinctly marked off from the body of the bone. 



The Squamosal, with its zygomatic process, is almost exactly 

 like that of the moose, the zygoma being directed downwards 

 and forwards, instead of being almost horizontal as in the other 

 Cervidde. This peculiar shape of the zygoma is due to the great 

 depression of the forehead, which, though somewhat less than in 

 the moose, is greater than in the deer. If the plane of the upper 

 molar alveolus be produced backwards, it will be found that the 

 distance from the summit of the sagittal crest to this plane is 

 much greater than in Megaceros (Cervalces 9 in., Megaceros not 

 quite 6). 



The Occiput. As Wistar pointed out, the occiput of the fossil 

 is rather deer-like, in lacking the indentation of the supra-occipital, 

 and in the greater flatness of the entire occiput. As in the moose, 

 however, the condyles are nearl}' in contact below, while in Gervus 

 they are quite widely separated. The basi-occipital has two large 

 rugosities just in advance of the condyles, as in Alces and Mega- 

 ceros. The paroccipital processes are stout and of the same 

 shape as in the moose, though somewhat shorter. The propor- 

 tions of the exposed part of the periotic are about as in that 

 animal. The same is true of the tympanic which does not form 

 an inflated auditoiy bulla. 



The structures at the base of the skull — sphenoids, pterygoids, 

 palatines, vomer and turbinals— need no special description, being 

 veiy much as in the moose. 



The Inferior Maxillary resembles the corresponding bone in 

 the moose more than that of the other Cervidse, but with some 

 differences. The jaw, as a whole, is somewhat shorter and broader, 

 the diastema and symphysis slightly shorter, and the coronoid 

 process shorter and heavier. 



The Dentition is like that of the moose, though with some 

 cervine features. The crowns of the upper molars are shorter 

 than in Gervus, bul us in some species of that genus they have
