ON THE FOSSIL CAMEL 



2. Advanced position and prominence of orbits. 



3. Elevation of sagittal and occipital crests and development of tem- 

 poral fossae. 



• f 4. Narrowness of nasal bones at the posterior extremity. 



5. Extreme depth of maxillary, producing an arched appearance in 

 the nose of the animal. 



6. Form of sphenoid and basillary portion. 



7. Number of bones on the external nasal aperture. 



This summary brings us at once to the comparison of our fossil 

 species with the existing Camelidae. 



In pursuance of the rule that we have proposed to follow in naming 

 the new species so as to ally them at once to the mountain series, 

 whence their remains have been obtained, we propose calling the largest 

 and that nearly approaching the Indian species, Camehis Sivalensis : to 

 the second or a smaller species, the description of which we shall enter upon 

 more fully hereafter, and which may perhaps have been more closely allied 

 to the Lama, we propose the name oi Camelus Antiquus. 



Camelus Sivalensis. 



Of the Camelus Sivalensis we draw our description from the remains both of 

 the skull and of the bony structure of the animal generally. We have at 

 present only portions of the skull to guide us. The remains of the lower jaw 

 however are perfect, including the coronoid processes. The articulating 

 ends of bones are in sufficient abundance, and in a sufficient state of preser- 

 vation, to enable us to form a very tolerable idea of the size and height to 

 which the animal must have attained. 



To commence with a comparison between the fossil skull and that of 

 the Dromedarius or common Camel in use in the Bengal Provinces. From 

 the imperfection of our fossil fragments, and the sutures not being dis- 

 tinctly traceable in most cases, we must be satisfied with a view, limited more
