The southern group : — 



3. Ovis Karelinij nob. 



The honis are moderately thick, with rather rounded edges ; 

 the frontal surface of the horn is very convex, whilst the 

 orbital surface is flat, getting narrower only in the last third 

 of its length. The horns are tliree times as long as the skull. 

 The basal and terminal chords rise parallel irt'th each other ; 

 the axil spiral of the horn fits on a cone with the base towards 

 the skull. The prcpmaxt'llce and maxillnries do not articu- 

 late with the 7iasals ; the same is the case with the lachrymals, 

 which latter are large and square, being rather wider than the 

 malar, and are partly separated from the latter by a protu- 

 berance of the maxillary. 



The neck is covered loith a mane of a ichite colour, shaded 

 with gret/ish brown. The light brown colour of the back and 

 sides is separated from the yelloicish white belly by a wide dark 

 line; the light brown colour gets gradually lighter toicards the 

 tail, till it becomes greyish white, not forming a sharply de- 

 fined round patch. On the back there is a sharply marked 

 dark line running from the shoulders down to the loins, I did 

 not find any soft hair under the long winter hair in October. 



Length 5 feet 10 inches to 6 feet, height at the shoulders 

 3 feet 6 inches ; length of the horn .3 feet 8 to 3 feet 9 inches. 



Obs. The figures of the skull of Ovis argali given by Blasius 

 (Saugeth. Ueutschl. p. 468) in the elongated form of the horns 

 resemble 0. Korelini; but by the orbital surface of the horns, 

 which gets regularly narrower from the base to the end, they 

 can only be referred to 0. argali. His diagnosis contains only 

 such characters as are common to both species. 



4. Ovis Polii. 



The horns are very large, laterally compressed, the edges 

 (except the nuchal one) being rounded ; the orbital surface is 

 concave, and commences to get narrower only at the last third 

 of its length. The horn is more than four times the length of 

 the skull ; the basal and terminal chords are not parallel, the 

 latter being more horizontal than the former ; the axil spiral 

 of the horn is cone-shaped, gradually narrowing till it reaches 

 the skull. The pra?maxilla3 do not articulate with the nasals, 

 whilst the maxillaries are separated from them by small 

 bones. The lachrymals are very large, and protrude a little 

 further forwards than the malars ; the anterior edges of both 

 articulate with the maxillaries by serrated sutures. 



The form of the head is prismatic, high and narrow. All
