REVISION OF THE PUMAS 593 



are small, low, and narrow and not of the same size. In another (No. 

 99659) they are enormously swollen and inflated posteriorly, and rather 

 sharply pointed anteriorly. It is probable that the medium condition 

 shown in No. 99658 is the normal, that No. 99659 is exceptionally 

 inflated, and that No. 99660 has the bullae imperfectly developed. 

 This is the more probable because of the difference in the bullae on 

 the two sides in No. 99660, the left being considerably smaller and less 

 perfect than the right.

FELIS CONCOLOR Linn. Brazilian Puma. 



Felis concolor Linn^us, Syst. Nat., ed. xii, Addendum to Vol. iii, Mantissa 

 Plantarum, p. 522. 1771. 



Type locality. — Brazil (probably southeastern Brazil). 



Characters. — Size medium ; color apparently yellowish fulvous ; 

 cranial and dental characters distinctive. 



Color. — The original diagnosis by Linnaeus is merely " cauda elon- 

 gata, corpore immaculato fulvo." It is based mainly on Brisson, who 

 states that the color is reddish yellow. Burmeister (whose description 

 is apparently of a specimen from Neu-Freiburg, southeastern Brazil) 

 gives the color as rather pale reddish yellowish gray ; with throat, chest 

 and inner sides of arms and thighs pure white ; belly yellow ; outside of 

 ears blackish brown with a yellowish spot ; tip of tail blackish brown. 

 (Thiere Brasiliens, Saugthiere, pp. 88-89, 1854). 



Cranial characters.^ — Skull of medium size, thin and light com- 

 pared with the North American and Chilean species ; face and frontal 



' The present description is based wholly on two skulls from Brazil in the col- 

 lection of the Biological Survey: an adult male, No. 100118 from Piracicaba, 

 Sao Paulo ; and an adult female without particular locality. For both I am in- 

 debted to the courtesy of Prof. Herman von Ihering. The male when young had 

 suffered some injury to the top of the head, in the posterior frontal region, as if 

 he had been dealt a blow with a machete. The resulting deformity may have pre- 

 vented the development of the sagittal crest.
