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 skuU, received from the Zoological Society. 



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

 from the Leyden Museum through M. Pranks as B. swmatranus, from 

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

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

 nose, with the adult skull of 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 skull which has had the nasal bone cut off 

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

 name of R. vjnicornis ; but I have little doubt it is a R. javanicus, 

 perhaps from Sir Stamford Raffles. 



In the oldest skull (723 d) the aperture under the zygoma is 



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

 In the adult skull (723 a) the aperture is 3 inches wide and 6 inches 

 1 line long. In the skull of the young specimen (723«) the aperture 

 is 2 inches 2 lines 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 a it is 5 inches 9 lines wide. 



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

 skulls 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 ' Neue nord. Beytrage ' (vii. p. 249), 

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

 with upper incisors. His specimen, by the misfortunes of war, fell 

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

 FossUes ' (ii. p. 26). Cuvier 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
