far as the rump. The throat marked by a mane of long buffy or whitish 

 hair from the chin to the chest. Top of snout from the interorbital re- 

 gion to the muzzle and far down on the sides to the lower level of the 

 eyes deep black, the blackness at muzzle spreading down around the 

 mouth and uniting with the black chin ; the upper lips whitish at tip 

 of snout and walnut-brown on the sides. Sides of head drab-gray 

 like the neck with a slightly lighter streak bordering the black face 

 blaze from the eye to the angle of the mouth. Crown seal-brown and 

 showing some contrast to the black forehead. Back of ears black 

 and united with the dark crown patch by a narrow bridge of dark 

 color, rest of base and inside pale drab-gray. 



No flesh measurements of the type are available but an adult male 

 specimen from the same locality, Xo. 181851, U. S. Nat. Mus., had 

 dimensions in the flesh as follows : Head and body, 2,000 mm. ; tail, 

 645 ; hindfoot, 515 ; ear, 200. The skull of the type shows consider- 

 able age, the last molars showing wear, the horn points being much 

 worn down and the fronto-nasal suture quite obliterated. Condylo- 

 basal length, 430 ; greatest length, 457 ; greatest breadth, 185 ; nasals, 

 222x40; orbit to gnathion, 300; length of premaxillse, 192; vertical 

 diameter of eye, 58; upper tooth row, 101 ; width of palate across 

 M 2 , 95 ; tooth row to gnathion, 142. Length of horns on curve, 15^ 

 inches; greatest spread. 20^ inches; spread at tips, i^}4. 



A series of twelve skins, with their skulls, of this new race is in 

 the National Museum from the Loita Plains and six skins and skulls 

 from the Kapiti or Athi Plains representing albojubatus. The series 

 from the Loita representing mearnsi shows much darker legs accom- 

 panied by darker body color on the chest, sides and underparts. In 

 the typical albojubatus of the Athi the legs are drab or tawny-olive 

 and never as dark as olive-brown or sepia. Xo difference in the color 

 of the throat, mane or forehead is evident in these two series but the 

 ears at the base in albojubatus show a tendency to lose the bridge of 

 dark color from the back of the ear to the crown patch. The horns 

 in the Loita Plains specimens agree in showing a much deeper sweep 

 downward from the head than do those of typical albojubatus from 

 the Athi Plains. 



Gorgon has been employed as the genus of the brindled wilde- 

 beests owing to their marked distinctness in skull shape and horns 

 from the white-tailed gnu which is the type of the genus Connochcctes 

 of Lichtenstein. Gorgon was proposed by Gray in 1850 for the 

 brindled wildebeest, G. taurinus.
