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 Camelopar- 

 dalis 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 another 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 difference 

 between them. 



The largest specimen (PI. XYI. figs. 5, 5 a) is a fragment 

 of a left upper jaw containing the two rear molars. The 

 back part of the maxilla, beyond the teeth, is attached, 

 and clearly proves that they belonged to a full grown animal. 

 These teeth were compared vpith 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 : —
