Hab. Sierra de Santa Barbara, Eastern Jujuy. Type from 
Sunchal, alt. 1000 m. Another specimen from San Rafael, 
same altitude. 
Type. Old male. B.M. no. 21.1.1. 2. Original num- 
ber 1036. Collected 15th July, 1920, by E. Budin. Pre- 
sented by Oldfield Thomas. 
With the exception of the comparatively pale long-skulled 
C. tueumanus no Cerdocyon has been described from anywhere 
near this region, the nearest localities for C. brasiliensis being 
over 800 miles to the eastwards. 
The unusually short, stout, inflated skull, with broad inter- 
orbital region, would seem to distinguish this Thous from any 
described form. Both skull and colour readily separate it 
from its neighbour C. tucumanus. 
Pseudalopex zorrula, sp. n. 
External appearance very much as in P. gracilis, but size 
much less. 
Coloration quite as in gracilis, that of the type matching 
some of the more reddish-suffused specimens of that animal. 
Head, neck, backs of ears, and fore limbs strong ochraceous 
tawny. Back with the usual black and white grizzling, with 
ochraceous underfur. Under surface more or less smoky
