It is t(> be uuticed that the colour t>f the helly is different in the 

 two sexes, owing to the niule generally having a Irrown patch in 

 the inguinal region, just in front of the hips, and this, with the browu 

 colour of the scrotum, gives a much darker aspect to the under side 

 than is the case in the females. 8ome few males are, however, with- 

 out the brovvn jjatches. 



[The habits of all the species of Rhinosciaras known to us are 

 identical and v>diat applies to one applies to all equally. They are 

 strictly terrestial and very shy, which accounts for their rarity in 

 collections. Their diet, judging from numerous specimens that we 

 have examined, is principally insectivorous, consisting of large ants 

 and beetles. The tongue is vei'V long and remarkably protrusible, and 

 it is probable that gritty matter taken up with the insects by means of 

 this organ accounts for the rapid wear of the teeth, which Messrs. 

 Thomas and Wroughton have commented on above. The animals are 

 generally found in the neighbourhood of large and rotten logs and, at 

 the least alai'ui, take refuge beneath or in any available hole. The 

 considerable number obtained was principally due to the efforts of 

 one of our Dyak collectors, who developed a remarkable capacity for 

 securing ground birds and nuimmals. — H. C. K. and C. B. K.] 



12. IIHINOSCIURUS PERAC'ER. 



Thos. and Wrought., Ann. Mag. N. H. (8). iii., p. 440 (1909). 



V 89. Maxwell's Hill, Perak, 3,600 feet. 1st September, 1908. 



B. M. No. 9, 4, 1, 252. Type. 



General colour daik ; light shoulder stripes scarcely perceptible ; 

 under surface of medium buffiness. Hands and feet dark, becoming 

 l>Iack on the fingers and toes. Tail jiairs tipped with buffy ochraceous, 

 rdther less broadly and cousiiicuously than in the more southern 

 forms. 



Skull curiously more like that of the Borneau laticaadatnK than of 

 the intermediate forms, the Indite similarly small, the muzzle not 

 quite so narrow and parallel sided. 



Dimensions of the Type measured in the tlesh : 



Head and body, 213 ; tail, 122 ; hind foot, 41 ; ear, 14 mm. 



Skull: greatest lenglh, 56; condylo-basal length, 52; greatest 

 breadth, 26; length of bullie, 11.7; upper molar series, exclusive of 

 l>^, 10 mm. 



Habitat and Type as above. 



The occurrence of this U/iiiwifciarus with a buffy-washed tail to the 

 north of hijjaioides is ciuious, for the latter appears to range quite 

 aci-oss the Peninsula, and to shut off jjcroxer from all the other 

 similarly-coloured forms to the sottth. Its skull is more similar to that 

 of the Borneau species than to leo, the species occurring next south 

 "f l"i>':i.i.'.>ulci<.
