DR. F. A. JENTINK. MAMMALS; 175 



haired. Underparts slaty, tipped with a feeble reddish brown. Forefeet grizzled, hindfeet 

 brownish ; the hairs on the extremities very short, with the exception of the white curved 

 hairs overlapping the well developed sharply pointed and arched claws. Tail with rather 

 large scales, the latter imbricated ; the scales are neariy hidden by the adpressed brownish 

 hairs, the latter are somewhat elongate towards the tip of the tail, forming there a smalj 

 pencil. The ears are elongated and pointed like some VesperUlio-ears, and folded like the 

 latter. Whiskers numerous, very long for such a small animal, viz. 65 mm. Anterior 

 extremities with four toes, the fifth being so small that only the flat nail is to beseen;hind. 

 feet five toe-ed. 



In the skull the brain-case is enormously developed compared with the anterior parts, 

 especially the muzzle is very short; conspicuous also is the very wide foramen magnum and 

 the broad zygomatic process of squamosal. The skull is very subtilely built, semi-transparent. 

 It has been figured on plate VII, figs. g, h, i,j, k, l; this saves a description of the dentition 

 too. The skeleton could not be saved, as it was so crushed and cracked that it was smashed 

 to pièces.

N°. 475. Old cf. Bivak Island, January 22. 1910 (skull). 

 Young. Lorentz River (skull). 



No anterior lower premolar; this seems to be characteristic for this species (N. L. M. 

 Vol. XXVI, p. p. 191 and 192).

Very young. „ „ (skull without anterior part of upper jaw). 



Very young. „ „ (lower jaw). 



Ail the lower jaws with anterior premolar. 



Mr. VAN NOUHUYS kindly informs me that the Alkmaar-specimens were gray-brown, 

 the extremities not ringed with white. Among the Pigs of the Pesegem-people and also 

 on the Wichmann Mountains (3000 m.) he saw spécimens which were spotted and others 

 which were coloured like our domestic pigs.
