unite with the middle third of the outer border of the nasals. The acoustic bullae are 

 relatively more expanded than in the Lion or Tiger. The canines do not show the longitu- 

 dinal grooves which characterize those of the Lion or Tiger.

4538. The skull of a female Jaguar (Felis Onca). 



The nasal bones show the characteristic breadth and flatness of their upper parts, and they 

 are less bent longitudinally than hi the Leopard : the fangs of both upper and lower canines 

 are more rounded, and do not show the longitudinal grooves. 



Purchased. 



4539. The right upper jaw and both rami of the lower jaw, with a great part of the 

 deciduous dentition, of a young Jaguar (Felis Onca). 



In the upper jaw the first and second permanent incisors are in place, and the point of the 

 third incisor is beginning to appear : the crown of the permanent canine is exposed on the 

 inner and anterior side of the fang of the deciduous one. The permanent premolar p 2 is in 

 place ; the permanent p 3 is exposed above and on the inner side of the anterior fang of the 

 deciduous carnassial d 3, and the permanent carnassial p 4 is exposed above the hinder fang 

 of the deciduous carnassial, and above the deciduous tubercular d 4, of which it is the proper 

 successor ; the permanent tubercular m 1 is in place, its development preceding, as usual, that 

 of the premolars. In the right ramus of the lower jaw the base of the deciduous canine and 

 the two deciduous molars are shown in place, and the crown of the permanent carnassial, m 1 , 

 has cut the gum. The crowns of the permanent canine, of p 3 the successor of the first milk- 

 molar, and of p 4 the successor of the second milk-molar, and the fangs of m 1, are exposed 

 from the inner side. In the left ramus of the same jaw the first and second permanent in- 

 cisors, the deciduous canine and the two deciduous molars are in place ; the permanent third 

 incisor and crown of the permanent canine, and of the premolars p 3 and p 4, with the fangs 

 of ml, are exposed from the outer side.

The nasal bones are more triangular and less flattened than in the Jaguar, and their upper 

 extremities extend further back than the rounded ends of the nasal processes of the maxil. 

 laries. The canines have been broken, apparently during the lifetime of the animal. 



From Africa.
