 chased by Mr. Bogoras at Baronesskorf Gulf. 



Mr. Buxton's measurements of three specimens in the flesh 

 are as follows :

 height, 840; head of humerus to head of femur, 760; girth, 1000; 

 girth of neck, 510. 



No. 18213, 2 . Total length, 1380 mm.; tail, 90; hind foot, 373. 

 No. 18210, $. juv. (quite young). Total length, 1070; tail, 86; 

 hind foot, 325; height, 665; head of humerus to head of femur, 665; 

 girth, 690; girth of neck, 330. 



The skull of No. 18211, adult male, measures: Basal length, 223 

 mm.; least interorbital breadth, in; greatest orbital breadth, 156; 

 mastoid breadth, 95; length of nasals, 68; breadth of nasals at mid- 

 dle, 38.5; palatal length, 131; length of upper toothrow, 72; length of 

 horns along outer edge, following the curvature, 588; spread at tips, 

 470; circumference at base, 255. 



The skull of No. 18212, an older and much larger male from Baron- 

 esskorf Gulf, measures: Basal length, 252 mm.; least interorbital 

 breadth, 125; greatest orbital breadth, 168; mastoid breadth, 95; 

 length of nasals, 83 ; breadth of nasals at middle, 43 ; palatal length, 

 137; length of upper toothrow, 65; length of horns along outer edge, 

 following the curvature, 730; spread at tips, 453; circumference at 

 base, 295. 



The skull of the adult female, No. 18213, measures: Basal length, 

 240 mm.; least interorbital breadth, 104; greatest orbital breadth, 144; 

 mastoid breadth, 80 ; length of nasals, 78 ; breadth of nasals at middle , 

 26; palatal length, 129; length of upper toothrow, 70; length of horns 

 along curvature, 167; spread at tips, 116. 



As the description and figure of this sheep given in 'Wild 

 Oxen, Sheep, and Goats of All Lands' (pp. 221-226, pi. xviiiA) 

 are quite misleading as to the color of the animal the following 

 description, based on a good series of specimens, is here pre- 

 sented. Eschscholtz's figure is also incorrect as to color and 

 does not agree well with the same author's good description.
