black lines are continued interruptedly down the back on to 
the rump, but laterally and on the shoulders the lines change 
into rosettes, which are about an inch in diameter, with dene 
fulvous centres. ‘Then below on the belly and on the limbs 
the rosettes again pass into black spots. Chin, chest, and 
groins white, with but little spotting ; belly heavily spotted. 
Limbs dull yellowish fulvous, the spots getting smaller ter- 
minally, being only about 3 inch in diameter on the meta- 
podials and disappearing on the digits. ‘Tail rather short, 
with 11 to 13 black rings, which are slightly broader than 
the light spaces between them. 
Skull small and delicate, very smooth, and without any 
trace of ridges or crests, with the usual exception of the 
lambdoid crest, and even this is low and little developed. 
Face short. Nasal region pinched in, but not markedly 
convex above, the profile running in an even scarcely convex 
line to the vertex. Postorbital processes small and weak, 
the brain-case but little constricted behind them. Bulle 
high and well inflated.

Compared with this, the Central-American representative 
of the group may be distinguished as follows :— 
Felis pardinoides oncilla, subsp. n. 
Size and general characters as in true Ff. pardinotdes, 
Fur of about the same length, and similarly directed back- 
wards on the nape, but much softer and richer throughout. 
Ground-colour much richer and deeper, and scarcely lightening 
on the sides or limbs; it is something near Ridgway’s clay- 
colour, but darker and glossier. Black lines of head and 
nape very strong, but the indistinct median dark nuchal line 
not present. Posterior back with a strong central black line, 
outside which rosettes begin to form at once. Lateral 
rosettes but little elongated, their centres much darker than
