MR. A. H. GARROD ON THE VISCERAL ANATOMY [NoV, 6, 



Mr. E. Gerrard has kindly lent me the skull for examination. 

 In its base it exhibits the characteristic peculiarities of the species 

 so clearly enunciated by Prof. Flower^ the vomer being free behind 

 and developed into a tongue-shaped process ; the mesopterygoid 

 fossa being expanded, and the free ends of the pterygoids everted at 

 the same time that they are broad. No second combing-plate is 

 present on the uncut first upper molar tooth. 



The animal is too young to be contrasted advantageously with 

 Prof. Peters's drawing^ of Rhinoceros inermis, Lesson. I have, how- 

 ever, taken the opportunity of comparing that figure with the skulls 

 of M. sondaicus in the CoUege-of-Surgeons' Museum, and fail to see

that there are sufficient differences to justify specific differentiation. 

 Prof. Flower had previously done the same, and had arrived at a 

 similar conclusion, as he found -.that even greater differences than 

 those pointed out by Prof. Peters' are to be detected in individuals 

 which are all undoubtedly of Indo-Malay origin.
