OF THE GENUS RHTNOLOPHUS.

Colour. 5 ad., skin ; Perak ; March ; teeth almost unworn. 

 Very different from Rh. lepidus. General effect of the colour of 

 the upper side : a dark shade of " Front's brown " with a tinge of 

 " hair-bi-own." On closer examination the fur of the upper side 

 proves to be composed of two kinds of hair : longer, thinner, straight 

 hairs, quite black ; and somewhat shorter, crinkled hairs of a 

 " hair-brown " colour ; the mixture of the colours of these two 

 kinds of hair produces the general effect. Base of hairs of iipjyer 

 side not lighter coloured. The fur of the upper side has a silvery 

 reflection (iridescence). Under side between "broccoli-brown" 

 and " hair-brown." A spirit-specimen from Selangor ( c? ad., 

 apparently the same age) is of the same colour. 



Skull. In addition to the characteristic in the diagnosis : the 

 " maxillar width," across the antero-external corner of m^ (a 

 character subject to exceedingly small individual variation in the 

 species of the lepidus-aectioia) is somewhat larger, giving this part 

 of the skull a somewhat broader aspect : 6"5-6*7 mm. ; in lepidus 

 6"2 mm. Gap in front between the maxillary bones somewhat 

 larger.
