458 DR. J. MURIE ON SAIGA TARTARICA. [June 9, 
Ist, the extraordinary shortness of the nasal region, the face, as it 
were, being scooped out, leaving only an exceedingly narrow exten- 
sion forwards of the maxillary and premaxillary bones; 2nd, the 
great vertical depth of the naso-maxillary region; 3rd, the rela- 
tively prominent, large, and staring orbit ; 4th, the very small, 
shallow zygomatic arch; 5th, the moderate-sized, roundish, occi- 
pito-temporal region ; 6th, the long, erect, tapering horns. 
In bird’s-eye view, or from above, the skull is elongate, somewhat 
diamond-shaped, the palato-maxillary being considerably longer 
than the parieto-occipital segments. The orbits form two salient 
projections, behind and above which the horns start forth. 
Examined in front, or facially foreshortened (as in fig. 4), the 
horns appear to slant well backwards, the frontal bone being rather 
depressed. The broad orbital rings stand well out. The short nasals 
are raised, below which the turbinal bones are exposed ; and beneath 
these, between the inner borders of the maxillaries, is an immense 
narial vacuity. The irregular-surfaced, long, narrow palato-maxillary 
shelf forms the floor of the forwardly jutting nares.
