lend to completely encircle liirht areas, and, loyether with tiie other 

 black marking's, are disposed as in F. /n rniiii<Ji-nii, but are very much 

 increased in si/.e. There is no light spot at the upper margin of the 

 nasal pad. Ears whitish cream-buff within, i)lack wilhoul, edged an- 

 teriorly with lawny, and with a large tawny spot on middle of black ex- 

 ternal surface. Tail irregularly spotted and banded with black, which 

 color greatly predominates. At base of tail, the light areas are tawny 

 above and white or gri/.zled below: terminal four or fi\e light rings, 

 hoary grayish, becoming successively narrower until obsolete towards 

 the tip, which is all black. Underparts butfy while, heavily banded 

 with elongate (not quadrate) black spots. 



Skull lUid teeth. — Decidedly larger than /VZ/.s- nidrnlis^ the largest skull 

 equalling the smallest adult male of Felis onrd from South America. 

 Teeth larger than those of V. eentrnlix, smaller than in F. onra. The 

 premolar teeth are narrower than in South American jaguai's. The 

 skull as a whole, aside from general size, is much more heavily ossified 

 than in Felis mttnillK, in this respect being comparable with the South 

 American F. ot/i-d. from which it is geographically separatetl by the 

 range of F. rent rails.

liemark-s. — In true hernandtsll, from the arid region of Mazatlan, in 

 the State of Sinaloa. not only is the ground color paler, but the light 

 areas are increased in size at the expense of the black, giving a decided 

 pallor. The pailern of the tail marking's becomes evident in /lenfiatde-sii 

 through reduction of black, and appears as interrupted longitudinal 

 stripes on basal three-tifths of tail: grovmd color buff at base, darkest 

 above and whitish below, and the subterminal hoary bands more plainly 

 marked than in fjotdmo/tl.
