MR. R. H. BURNE ON THE 



curve, forming in some Antelopes (text-fig. 10, B) a veritable 

 hook, and in all cases ofi'ers a veiy broad surface for the insertion 

 of the occipito-styloideus muscle. 



In the Giraffe and Okapi (text-fig. 10, A) and in the Camels 

 and the Perissodactyl Ungulates the process is relatively small, 

 and is directed upwards, forming a simple swelling or tuberosity 

 of the upper end of the styloid bone.

Salivary Glands. 



The submaxillary gland (text-figs. \, '6, smoc.gl.) is similar in 

 position, form, and relative size in the Giraffe and Okapi, and 

 is closely comparable also to the same gland in Antelopes and 

 Domestic Ruminants. 



In the Giraffe and Okapi the gland gives off two main 

 tributary ducts, one from its posterior and one from its anterior 

 end. The parts drained by these two collecting ducts can be 

 readily and completely separated from one another in the Giraffe, 

 but this is not the case in the Okapi.
