PITHECHIR MELANURUS. 227 



Head and body 209 



Tail 186 



Hind foot with claws 30 



Ear 15 



Length of skull 41 



Greatest breadth 22 



Length of upper molar series 9 



Distance between upper incisor and first molar . 11 

 Incisors smooth , upper incisors orange colored , lower 

 ones yellow. 



Fur very long and very soft to touch; hairs of belly 

 uniformly reddish white in the Sumatra-specimen , pure 

 white in the Java-specimen : all the other hairs have their 

 basal half dark mouse-color and their terminal half more 

 or less reddish (fauve apud Cuvier) : the tail is reddish , 

 perhaps decolored; ears and feet reddish, nails horn-brown. 

 For the rest 1 refer to Cuvier and v. d. Hoeven. From 

 all what has been reported concerning it, we may now 

 conclude , that Pithechir melanurus S. Muller lives in Su- 

 matra and West-Java, that Duvaucel's drawing represents 

 the animal in its natural size and has been satisfactorily 

 accurate drawn , and finally that the animal is a true 

 Mouse. 



NB. There is in the » Bijdragen tot de Dierkunde van 

 Natura Artis Magistra, Feestnummer, Amsterdam, 1888" 

 a paper, written by Mr. K. N. S wierstra, one of the mem- 

 bers of the scientific staff of that splendid institution, and 

 entitled »Naamliist van levende dieren, 1838 — 1888." On 

 p. 15 of that paper the author states that in 1871 lived 

 in the named Zoological Garden a specimen of Pithicheirus 

 melanurus from East-Java, Padjarakan. I am imformed by 

 Mr. Swierstra that unhappily that animal has not been 



The specimen from Java however is the largest and the lightest colored and 

 has the white belly (see also v. d. Hoeven, p. 51 and A. M. N. H. p. 471), 

 therefore the correction in A. M. N. H. should have been as follows: »The 

 specimen from Sumatra is . . . The larger specimen is from .7«m and of a lighter 

 red colour."
