Amman). 



The circumference of the base of each horn is sixteen inches nine lines ; the length of the 

 horn, following the greater curvature, is three feet five inches and a half. The premaxillary 

 bones and paroccipital processes have been removed : the facial part of the lacrymal has a 

 depression for the lacrymal pit.

 Argali, or Rocky -Mountain Sheep (Ovis montana). Hunterian. 



3775. The horns of the Ovis montana. Presented by the Hudson's Bay Company. 



3776. The frontlet and horns of the Burrhal Sheep (Ovis Burrhal). 



The horns are broader at the base in proportion to their length and much less curved than 

 in the Argali or common Ram, and their bases come almost into contact upon the upper sur- 

 face of the skull. The curve is upwards, outwards, then downwards and a little backwards, 

 the points scarcely reaching the level of the base. 



Purchased. 



3777. The horns of the Ovis Burrhal. 



The sheath is removed from the right horn to show the proportion and form of the core ; 

 and both core and sheath are longitudinally bisected on the left horn. 



Purchased. 



3778. The skull and horns of the Ladak Argali (Ovis Vignei). 



The bases of the horns meet upon the summit of the skull, whence they diverge with a 

 wide curve upwards, outwards, backwards and downwards in almost the same plane. The 

 premaxillaries join the nasals, and the facial part of the lacrymal is deeply impressed by the 

 lacrymal pit. 



From Thibet.
