4542. The skull of a young Leopard (Felis Leopardus). 



It shows a state of the dentition comparable with that of the Jaguar No. 4539. 



Hunterian. 



4543. A vertically and longitudinally bisected and mutilated cranium of a Leopard 

 (Felis Leopardus). 



It shows the same general characters of the interior of the cranium as that of the Lion, 

 No. 4483. The temporal bone has been removed from the left moiety, showing the extent 

 of the cerebral cavity which is closed by the squamosal in front of the bony tentorium and by 

 the petromastoid behind that part. 



Hunterian. 



The following, to No. 4559 inclusive, are parts of the same skeleton of a Leopard (Felis 

 Leopardus) : 



Purchased. 



4544. The skull, in three transverse sections. 



The posterior section, as compared with the corresponding one in the Dog (No. 4439), 

 shows the more compact walls of the cranial cavity, the greater breadth of the basioccipital, 

 the greater extent of the bony tentorium, and the greater capacity of the acoustic bullse. In 

 the middle section may be observed the narrower communication between the meatal com- 

 partment of the tympanum and the bulla, the absence of the venous sinus which opens 

 behind the zygomatic arch in the Dog, and the presence of a smaller venous canal, which 

 conveys the blood of the petrosal sinus to the outlet at the middle of the outer side of the 

 bulla : a bristle is passed through this sinus on the left side. The anterior section shows the 

 development of the presphenoidal air-cells in the Leopard, and the extension into them of 

 processes of the turbinals beneath the rhinencephalic chamber : this chamber shows a 

 rudiment of a crista galli at its lower part. In the frontal sinuses exposed above it 

 may be seen the apertures of communication with the superior meatus of the olfactory 

 chamber. 



4545. The lower jaw. 4546. The atlas. 



4547. The dentata. 4548. A cervical vertebra. 



4549. An anterior dorsal vertebra. 4550. The right scapula. 



4551. The right humerus. 



The inner condyle and the intercondyloid space are both perforated.
