204 BUBALUS MINDORENSIS. 



female much more backward ; the vomer in the female is 

 of about double the size of that bone in the male and is 

 much more prominent ; the posterior palatine foramina are 

 placed much more backward in the female than in the 

 male (Plate 10). The coronoid processes are more curved 

 in the female than in the male , and in the female the 

 incisor-series is much more inclined foreward. I recorded 

 here a series of sexual differences, there are however still 

 a great deal more which are as striking by comparing 

 the skulls as it is difficult nay impracticable to describe 

 with sufficient accuracy. 



Considering the peculiar white markings the Tamarao 

 reminds strongly the Anoa ; it is as it were an enlarged 

 edition of the Anoa , but the molars — as has been pointed 

 out by Dr. B. Hoffmann — the broad ribs, the horns and 

 the thinly spread coarse hairs remind the true Buffalo ^^o 

 the size and some cranial peculiarities. As the Buff'alo- 

 characteristics are preponderant, I call it provisionally with 

 Père Heude Bubalus mindorensis ^ although I confess that 

 there is reason to the supposition that it perhaps once 

 may be demonstrated to be merely a hybrid between Bu- 

 balus bubalus and Anoa depressicornis. This can be made 

 out by cross-breeding and therefore is a problem to solve 

 by Directors of Zoological Gardens and 1 recommend this 

 most scientific inquiry very much to those gentlemen. If 

 later on it appears that the Tamarao is not a hybrid, than 

 I think it needs a new generic title, as it is neither a 

 true Buffalo nor a true Anoa.
