tend to completely encircle light areas, and, together with the other 

 black markings, are disposed as in F. kernandem, but are very much 

 increased in size. There is no light spot at the upper margin of the 

 nasal pad. Ears whitish cream-buff within, black without, edged an 

 teriorly with tawny, 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 grizzled below: terminal four or five light rings, 

 hoary grayish, becoming successively narrower until obsolete towards 

 the tip, which is all black. Underparts butty white, heavily banded 

 with elongate (not quadrate) black spots. 



tfkull <ind teeth. Decidedly larger than Felix mif-mli*, the largest skull 

 equalling the smallest adult male of Felix o/tca from South America. 

 Teeth larger than those of F. cenfralix, smaller than in F. onrn. The 

 premolar teeth are narrower than in South American jaguars. The 

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

 than in Ff/i* ccnfrnfix. in this respect being comparable with the South 

 American F. onctt. from which it is geographically separated by the 

 range of F. <-ent)'Ux.

 of Chiapas, Mexico: 1)70)5, U. S. National Museum, from Tehuantepec,

 mensions: basilar length of Hensel, 211, 217, 227: zygomatic breadth, 178, 

 188, 180; mastoid breadth, 111, 112, 113: least interorbital breadth, 49, 

 51, 50: distance between tips of postorbital processes, 74, 81, 75: least 

 postorbital breadth, 44, 47, 40; length of nasals on median line, 02, 07, 

 (50: greatest breadth of nasals, 43, 40, 48; distance from foramen mag 

 num to posterior border of palate, 109, 111, 115: from posterior border of 

 palate to middle incisor tooth, 104, 109, 111: length of postpalatal fossa 

 from base of hamular process, 35, 3(5, 30: distance between upper car- 

 nassial teeth, 00, 57, 58: between upper canines, 30, 30, 39: greatest 

 length of mandible, 178, 179, 182; greatest height of mandible, 90, 93, 

 90; length of upper incisor toothrow, measured on alveoli, 32, 31, 33: 

 distance across upper canines, 71, 09, 72; length of upper lateral tooth- 

 row, 78, 79, 82; length of premolar series, measured on alveoli, 52. 50, 

 54: crown of upper carnassial, 27 by 13, 25 by 14, 27 by 14; crown of 

 middle upper premolar, 17.3 by 9.2, 17 by 10, 18 by 9.3. 



Remarks. In true hernandesii, 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 pattern of the tail markings becomes evident in hernatidesii 

 through reduction of black, and appears as interrupted longitudinal 

 stripes on basal three-fifths of tail; ground color buff at base, darkest 

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

 marked than in goklmani.
