598 MERRIAM 



Sao Paulo, Brazil (No. 100118U. S. National Museum, Biological 

 Survey Coll.) presents the following differences : nasals more angular 

 posteriorly (less bluntly truncate) ; bullae smaller; basioccipital broader 

 between bullae ; premaxillae more swollen over canines (owing to 

 larger size of these teeth) ; presphenoid much narrower posteriorly 

 between wings of pterygoids ; suture between presphenoid and basi- 

 sphenoid not closed ; under jaw more massive and more swollen under 

 tooth row ; basal half of anterior border of coronoid process much 

 more broadly expanded transversely ; upper incisors and canines much 

 larger and heavier; middle upper premolar and lower premolars 

 larger ; body of upper carnassial thinner and lacking the external angle 

 of concolor (the part occupied by the angle in cowco/or being concave) ; 

 inner tubercle (protocone) very much larger than in any other Puma 

 1 have seen ; posterior end of crown of middle upper premolar curved 

 strongly outward ; 2d lower premolar much broader posteriorly ; and 

 nearly twice as massive as in coitcolor ; lower carnassial with anterior 

 blade more flattened or ' dished ' on outer side ; upper molar twice 

 as large as usual (crown 10 mm. in length). 



Remarks. — The skull from Santiago, Chile (36851), on which the 

 present description is based, is not full grown (evidently in second 

 year) , and the cranial characters are not full}- developed. The dental 

 characters, however, are shown to unusual advantage, the teeth being 

 unworn. The most noteworthy tooth characters are the enormous 

 size of the 2d upper and lower premolars and upper molar, and the 

 large size of the inner tubercle (protocone) of the upper carnassial. 

 The upper carnassial measures 24 x 12.S mm. The skin of the head 

 and neck of this specimen differs from the type of J^. puma patagon- 

 ica from east base of Andes, Patagonia, in having the face and head 

 darker and browner (quite different from the clear gray of patagonica) ; 

 neck decidedly moi^e fulvous ; ears without distinct markings.

Characters. — Size large ; color gray ; black of ears nearly obsolete ; 

 skull and teeth large and massive ; frontals low (depressed contrasted 

 with concolor and the North American forms) , giving the cranium an 

 appearance of unusual length ; tooth characters distinctive.
