MAMMALS OF BORNEO. ^iS 



coarse bristles on the under surface, where the scales are more 

 convex and more distinctly imbricate than above. Ears short, 

 rounded, almost naked. Body clothed with hair of two kinds, 

 the underfur soft and woolly, the longer hairs coarse bristles. 

 Claws curved, not retractile. Skull very long and narrow, 

 third upper premolar much larger than the second, and having 

 three roots. The specimens from Sara\\'ak differ from the 

 typical form in being of white colour, only a part of the longest 

 and strongest hairs on the trunk being black. The head, legs, 

 and tail are pure white. This is merely a local variety. This 

 white hedge hog is purely nocturnal, and lives under the roots 

 of trees. Its food consist of insects. It has a very offensive 

 smell, and is known to the natives as ' tikus bulan ' or ' agi 

 bulan.' Tikus in Malay means a rat, and bulan is the moon. 

 Probably the name is given on account of its nocturnal habits. 

 It is caught by the natives in spring traps called ' jirats,' but 

 is not often eaten on account of its overpowering smell.

\n a paper on the mammals of Mount Kina Balu, by 

 Mr. Thomas, on a collection made by Mr. John Whitehead, 

 which was published in the P.Z.S., of April, 1889, page 229, 

 I see he gives the name of Hylomys suillus dorsalis to a variety 

 of this species found between the heights of 3000 and 8000-ft., 

 the description of which is as follows. Essential character as 

 in the typical varietv, but with a more or less distinct black 

 line running from between the eyes down the neck to the 

 middle of the back.
