242 EXTINCT AND VANISHING MAMMALS 



At the present time what few may remain are probably to 

 be found in the Florida Everglades and in southern Louisiana. 



TEXAS COUGAR 

 FELIS CONCOLOR STANLEYANA Goldman 



Felis concolor Stanley ana Goldman, Proc. Biol. Soc. Washington, vol. 51, p. 633, Mar. 



18, 1938 ("Bruni Ranch, near Bruni, southeastern Webb County, Texas"). 

 SYNONYM: Felis concolor youngi Goldman, Proc. Biol. Soc. Washington, vol. 49, p. 137, 



Aug. 22, 1936. (Preoccupied by Felis youngi Pei, for a fossil Chinese species.) 



Goldman has lately distinguished the cougar of southern 

 and central Texas and northeastern Mexico as larger than 

 azteca, with lighter upper parts of a more grayish tint, black on 

 tail usually more restricted, the dentition heavier, the nasals 

 depressed. It is smaller and paler than hippolestes to the 

 north. Total length of the type, 2,134 mm.; greatest length of 

 skull, 220 mm. A series of specimens examined by Goldman 

 represents 16 localities in Texas, and there were also two from 

 Matamoros, Tamaulipas, across the border in northeastern 

 Mexico. On the east it presumably intergrades with the race 

 coryi of Louisiana and Florida. Its general status may be 

 considered together with that of its near ally: 



MEXICAN COUGAR 



FELIS CONCOLOR AZTECA Merriain 



Felis hippolestes aztecus Merriam, Proc. Washington Acad. Sci., vol. 3, p. 592, Dec. 11, 

 1901 ("Colonia Garcia, Chihuahua, Mexico"). 



The characters claimed for this cougar are its large size, 

 though slightly smaller than the Montana hippolestes, "general 

 color dull fulvous [as in the latter] ... but tail darker, 

 browner, with longer black tip and no white underneath"; ears 

 almost wholly black. The skull is large and massive, though 

 not equalling that of hippolestes, but shorter and the teeth 

 somewhat smaller. The total length of an adult male, the 

 type, was 2,268 mm.; tail vertebrae, 731; basal length of skull, 

 171.5. It is thus a somewhat larger, duller animal than browni. 



The range of this race is believed to extend from the southern 

 border of the United States in Arizona and New Mexico, south 

 into Mexico for an undetermined distance, but probably over 

 the tableland in at least the northern half. Of its present 

 status in Mexico and Arizona, little information is at hand.
