This grey Mexican representative of the F. Wiedit group 
contrasts markedly in colour with the tawny forms found to 
the south of it from Costa Rica to 8. Brazil. 
I can find no tenable name applicable to this species, that 
of F. meaxicana, de Sauss., bemg antedated several times 
over in other groups of the genus. Its earliest use appears 
to have been by Kerr in 1792, who applied it to an ocelot. 
In Group ITI. the following is a description of two fresh 
specimens apparently assignable to the little-known F. pardi- 
noides, Gray, to which Hensel’s “ F. guigna, Mol.,” should 
also be referred :— 
Size comparatively small. Fur rather harsh and close. 
General colour dark, owing both to the dark tone of the 
ground-colour and the closeness of the spotting. Ground- 
colour along dorsal area light fulvous, becoming markedly 
lighter on the sides and white on the belly. Face with the 
usual white supraorbital line, interrupted black frontal lines, 
and the two black lines running back on the cheeks to below 
the ear. Back of ears black, with the usual whitish patch 
small but well defined. Top of neck with an indistinct black 
median line, outside which there are two pairs of strong 
clearly defined black lines, and a third less defined one on 
the level of the outer base of the ear. ‘The narrow central
