Hah. Java. Skull of type from Mus. Leyden. / 



In the British Museum there are three skulls belonging to this 

 species : — 



1. A skeleton of an adult animal with a skull, purchased from the 

 Leyden Museum, from Java. 



2. An adult skull, received from the Zoological Society. 



3. A skeleton with the skull of a half-grown animal, received 

 from the J^eyden Museum through M. Franks as li. Sumatra nus, from 

 Sumatra. The skull agrees in all particulars, especially in the form 

 of the occiput and the concavity and breadth of the forehead and 

 nose, with the adult skidl oi R. javanicus from Java ; so that there 

 must have been some mistake in the name and habitat ; perhaps the 

 wrong skeleton was sent. 



There is also an adult skuU which has had the nasal bone cut off 

 (722 7(), which was received from the Zoological Society under the 

 name of li. unicornis ; but I have little doubt it is a Ii. javanicus, 

 perhaps from Sir Stamford Eaffles. 



In the oldest skidl (723 c?) the apertiire under the zygoma is 



3 inches 7 lines wide in the widest part, and 4 inches 9 lines long. 

 In the adult skull (723 «) the aperture is 3 inches wide and G inches 

 1 hue long. In the skull of the young specimen (723 c) the aperture 

 is 2 inches 2 Hues wide, and 4 inches 7 lines long. The greater 

 width is produced by the skull under the zygoma becoming so much 

 narrower as the animal becomes aged. In 723 d this part is only 



4 inches 7 lines, and in 723 « it is 5 inches 9 lines wide. 



In the Museum of the Eoyal College of Surgeons there are Jive 

 skuUs that appear to belong to this species, but one or two of 

 them are in a bad condition (nos. 2970 and 2971, the rest are not 

 numbered). 



Camper, who paid great attention to this species of Rhinoceros, in 

 a letter to Pallas, printed in the ' Xeue nord. Beytriige ' (vii. p. 249), 

 first pointed out that there were two Asiatic one-horned Rhinocerotes 

 with upper incisors. His s])ccimen, by the misfortunes of war, fell 

 into the hands of Cuvicr, and was described by him in the ' Ossemens 

 Fossiles ' (ii. p. 26). Cuder regards the height of the occipital arch 

 and the want of the apophysis on the upper edge of the intermaxil- 

 lary as the chief character of the Javan species ; but the apophysis
