I have not enough material at present to form a completely 

 correct conclusion as to the specific value of the above average 

 measurements of the skull for specimens of different ages. 



I annex here a list of the comparative measurements of not 

 quite adult specimens : — 



Length from the nose to the 



tail 



Height at the shoulders .... 



Length of the horn 



Distance between the tips of 



the horns 



Width of the orbital surface of 



horns 



„ nuchal surface 



„ of horns .... 



„ frontal surface 



of horns ....
