 The southern group : — 



3. Ovis Karelini^ nob. 



The horns 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 three times as long as the skull. 

 The basal and terminal chords rise parallel with each other ; 

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

 the skull. The prcemaxillce and maxillaries do not articu- 

 late loith the nasals ; 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 nech is covered with a mane of a white colour., shaded 

 with greyish hrown. The light hroion colour of the hack and 

 sides is separated from the yelloxoish white helly hy a wide dark 

 line; the light hrown colour gets gradually lighter towards 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, lieight at the shoulders 

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



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

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

 resemble 0. Karelini] 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 thn-d 

 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 prsemaxillse 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
