1 68 PATAGONIAN EXPEDITIONS: ZOOLOGY. 



Felis concolor puma Prichard, P. Z. S., 1902, I, 273 (field notes) ; Through 

 Heart of Patagonia, 1902, 44, 45 (description and text figure of 

 animal), 242-244 (habits), 251-253 (habits and distribution). 

 Felis pinna patagonica Merriam, Proc. Washington Acad. Sci., Ill, 1901, 

 598 (Dec. II, 1901). East base of Andes, Patagonia, lat. 47° 30'. 



''Color. — Upperparts ash gray, everywhere abundantly mixed with 

 black hairs, the median dorsal region from top of head to end of tail suf- 

 fused with buffy ; belly buffy gray, the hairs much longer than on the 

 back; pectoral and inguinal regions soiled whitish; throat gray; chin and 

 lips white, the posterior part of upper lip and cheeks suffused with buff; 

 patch at base of whiskers gray (instead of black) ; rest of face gray, except 

 a buffy streak above and below the eye ; backs of ear gray, with apical 

 third and a faint basal band dusky ; feet buffy gray ; tail pale buffy fulvous 

 above, ash gray below, with only the extreme tip dusky. 



" Cranial CJiaracters. — Skull massive, elongate ; facial and frontal 

 regions low and narrow^ ; interorbital region narrow ; nasals rather broad 

 posteriorly and obliquely truncate ; sagittal crest low, continuous to frontal 

 shield ; bulLx rather large ; postpalatal notch broad ; the palatal margin 

 nearly straight ; presphenoid normal. Canines large (the upper ones 14.5 

 mm. in diameter) ; crowns of premolars and carnassials long ; upper molar 

 small (as usual in the group) ; inner cusp (protocone) of upper carnassial 

 very small. Compared with the skull of F. puma from Santiago, Chile, 

 the following tooth differences are conspicuous : crown 2d upper pre- 

 molar larger and thinner; crown of upper carnassial longer, with inner 

 tubercle greatly reduced ; upper molar small (less than half the size of 

 this tooth \x\ pjtma) ; 2d lower premolar smaller (decidedly less sw'ollen) ; 

 lower carnassial decidedly larger. 



"Compared with an old male concolor from Sao Paulo, Brazil, the facial 

 and frontal regions are very much lower ; frontal flatter ; bullae smaller ; 

 presphenoid narrower ; sphenoid suture distinct ; postpalatal notch broader ; 

 sagittal crest present ; underjaw more massive, the symphysis much longer ; 

 canines much larger ; crown of second upper premolar much longer and 

 narrower; crowns of upper and lower carnassial (particularly the lower) 

 decidedly longer ; crowns of lower premolars longer, the 2d much more 

 swollen posteriorly. 



''Remarks. — Compared with the skin of a head of F. puma from San- 

 tiago, Chile, the color of the corresponding parts in patagonica is lighter
