Dr. N. Severtzoff on the Mammals of Turkestan. 211 



round the neck is a pure white mane ; and along the vertebral 

 column from the shoulders to the loin there is a dark line. 

 The light greyish hrown colour of the sides shades ojf into white 

 on the belly; there is a white patch round the tail^ which is 

 hounded above by a rather dark line ; but downwards the white 

 extends largely over the hind part of the thighs^ and shades 

 gradually into the hrown colour of the legs. I did not observe 

 soft under-hair below the long winter hair in the month of 

 October. 



Length 6 feet 7 inches, height 3 feet 10 inches ; length of 

 horn 4 feet 9 inches. 



5. Ovis Heinsii. 



The horns are not massive ; they are laterally compressed, 

 and have three sharp edges ; the inner spiral would fit on an 

 inverted cone, with the base towards the skull. The maxil- 

 laries are separated from the nasals by a small bone ; the 

 pra^maxillaj articulate only with the maxillaries, and do not 

 touch the nasals at all. The anterior edge of the lachrymal 

 is rounded between the maxillary and malar, where a small 

 process is visible ; the malar in front finishes in three rather 

 rounded processes ; the middle one is the largest, and is about 

 as large as the process of the lachrymal, which latter, like the 

 malar, is broad and short. 



This species is known only from skulls of middle-aged spe- 

 cimens with not completely developed horns. Specimens seen 

 by me at rather a great distance appeared to be greyish brown ; 

 but I could not exactly define the colour. The height, judging 

 from the skulls, would be a little less than that of Ovis 

 Karelini. 



6. Ovis nigrimontana. 



The horns are not massive ; the nuchal edge is very sharp, 

 and the two other edges are not much rounded ; the frontal 

 surface is narrow, the two other surfaces are rather concave ; 

 the orbital surface commences to get narrower on the last third 

 of the horn, which is three and a half times as long as the 

 skull. The basal and terminal chords are not parallel, the 

 latter being more horizontal ; the inner spiral of the horn is 

 cone-shaped, getting a little narrower towards the point of 

 the horn. The preemaxilla^ articulate with the nasals, which 

 are separated from the maxillaries by the small bone between 

 them. The lachrymal is elongated, somewhat narrow, loith 

 one rounded process, and comes more forward than is the case 

 with the malar ; the front edge of the latter is straight, and 

 joins the lower edge in a sharp angle ; a process of the maxil- 

 lary fits in between the two above-mentioned bones. 



The head is pyramid-shaped, broad and blunt.
