Hence the authors conclude that there belonged to the Sewalik 

 fauna a true well-marked species of giraffe closely resembling the 

 existing species in form, but one-third less in height, and with a 

 neck proportionately more slender ; and for this small species they 

 propose the name Camelopardalis Sivalensis. 



Second Fossil Species of Giraffe. — The fossil specimens next to be 

 described have been in the possession of the authors ever since 

 1836. They are fragments from the upper and lower jaws of an- 

 other fossil species of giraffe, in which the teeth are so exactly of 

 the same size and form with those of the existing species, and so 

 perfectly resemble them in every respect, that it requires the calipers 

 to establish any difterence between them. 



The largest specimen (PI. II. fig. 3 a. 3 b.) is a fragment of a left 

 upper jaw containing the two rear molars. The back part of the 

 maxillary, beyond the teeth, is attached, and clearly proves tha,t 

 they belonged to a full-grown animal. These teeth were compared 

 with the teeth, in the same stage of wearing, contained in the head 

 of an adult female giraffe belonging to the museum of the College 

 of Surgeons, and the fossil and recent teeth were found to agree 

 together in the most minute particulars. The following are the 

 corresponding dimensions of the fossil and recent teeth : —
