140 Mammalia of Southern Brazil, 
42. Canis vetulus Lund. 
One skin with skeleton, and one separate skull, from Chapada. 
43. Canis entrerianus, Burmeister, Reise durch die La Plata Staten 
I am not as certain of the identification of this species as I 
would wish, and find it easier to determine what it is not than what 
it is. It differs from the preceding two species as follows : 
C. cancrivorus ; Mandibular angle robust, truncate; posttympanic 
process adherent to bulla ; larger ; sectorial teeth relatively 
C. vetulus; mandibular angle slender, acute; posttympanic process 
adherant to bulla; smaller; sectorial teeth relatively small. 
C. entrerianus; mandibular angle slender; acute; posttympanic 
process well posterior to bulla, but connected at base; larger; 
sectorial teeth relatively large. 
This supposed C entrerianus agrees closely in general characters 
with the C.griseus, Gray, described by Burmeister ^ excepting in the 
superior size. It agrees in dimensions with the C. azarae Cuv. but 
differs from both that species and the C magellanicus Gray, in the 
possession of but one inferior premolar tooth with posterior cutting 
lobe instead of two. It also differs from both these species, and 
agrees with the C. griseus in the wide separation of the premaxillary 
and frontal bones. The general color is reddish, the hair on the an- 
terior regions above, yellow near the tips, and brown at the tips, the 
brown becoming blackish on the posterior regions and the tail. 
Limbs light clean rufous; soles reddish brown. Belly and neck 
white, a gray band crossing just in front of the breast. Chin black 
except at tip, which is vrhite. Upper surface of ears (which are 
large) bright rufous. The animal is at least as large as the red fox. 
The coloration differs from that of C.griseus only in not show- 
ing the two white spots on the throat as described by Burmeister.
