REVISION OF THE PUMAS 585 



In color the Florida Puma comes nearest to the widely remote F. 

 batigsi costaricensis of Central America, with which it nearly agrees 

 in the red of the back; but the face, legs and feet are grayer (less 

 fulvous), and the tail is very different, being dark brown with a 

 blackish stripe along the median line above ; in bangsi the upper side 

 of the tail is uniform dark reddish fulvous without trace of a dorsal 

 stripe. 



Measuret7ients. — An adult male [tail and feet measured from dry 

 skin by O. Bangs]: total length 2057; tail vertebrae 760; hind foot 

 280. An adult female: total length 1918; tail vertebrae 670; hind 

 foot 271. 



Cranial ineasurements. — Largest of 2 males, and largest of 2 

 females (females in parentheses) from Sebastian, Florida : Basal 

 length 175 (158); occipito-nasal length 193 (174); zygomatic 

 breadth 152 (123); occipito-sphenoid length 66 (59); postpalatal 

 length 92.5 (82.5) ; interorbital breadth 44 (39) ; length of upper 

 carnassial on cingulum 23.9 (22.8).

 Mountain Lion. 



Felis hippolestes Merriam, Proc. Biol. Soc. Washington, Vol. xi, p. 219, July, 

 1897. 



Type locality. — Wind River Mountains, Wyoming. 



Characters. — Size largest of the knowni members of the group ; color 

 dull fulvous ; skull large and massive with highly developed sagittal 

 crest. 



Color. — Upperparts and sides dull pale fulvous brown, dai'kest on 

 middle of back and tail ; tip of tail black ; face from nose to eyes gray- 

 ish brown ; a pale patch over each eye ; back of ears blackish ; chin, 

 lips (except dark patch at base of whiskers), throat, breast, inner side 

 of forelegs, inguinal region, and hinder part of belly soiled white ; 

 under side of tail grayish white. 



Cranial characters. — Skull largest of the known species ; heavy and 

 massive ; frontal region elevated but less elevated than in males of 

 olympus ; sagittal crest highly developed and arched ; interorbital region 

 broad [interorbital breadth in adult males about 48-50] ; under jaw 

 long, large and massive, somewhat swollen under premolars. Teeth 

 large and powerful, the upper carnassial and 2d premolar much heavier 

 and broader than in aztecus. Skulls of female hippolestes from the 

 Rocky Mountain region are sometimes difficult to distinguish from 

 males of aztecus from Chihuahua.
