parts rather similar in colour to those of females of papuanus, 

 whereas the females are (approximately) liglit huffy- (or even 

 cream-) woodbrown above, cream-huffy beneath. A similar 

 sexual difference in colour is found in iV. geminus, major, and 

 scitulus, and so far as this character is concerned N. cephalotes 

 therefore stands nearer these species than does N. papuanns. 



Prom N. (jeminus the present species is readily distinguished by 

 its smaller size, a difference perhaps even more strongly pronounced 

 in the skulls and teeth than in the external dimensions (see table 

 below). 



In the Amboina group (or in any case in Burn) N. ceplialotes 

 occurs together with N.varius; the latter species is at once dis- 

 tinguished by its small size (forearm 55 mm.), mottled colour of the 

 upperside, and the completely fused cusps of p^ 



X.papicanit!^. N.cephalotes. N. geminus.

C'o?o»>-.— Adult males. 10.3.4.10, skin. Coram, October : Back 

 uniform fawn-drab slightly tinged with wood-brown and with the 

 seal-brown dorsal strij)e sharply defined along the whole of the back ; 

 individual hairs (outside dorsal stripe) dark slate at extreme base, 

 then light wood-brown (this colour partly showing through in the 

 arranged fur), with narrow darker brown tips. Nape of neck 

 similar to back, but slightly more greyish and without median 

 stripe. Crown wood-brown with very short darker brown tips to 

 the hairs ; sides of head fawn-drab. Breast and belly light drab- 

 grey tinged with pale yellow (perhaps rather a very pale shade of 

 tawny-olive) ; flanks and anal region fawn-drab. — A male skin 

 from Buru (August, 10.3.3.27) is similar in colour, but with the 

 drab element of the colour of the back rather more ])ronounced, the 

 breast and belly light fawn-grey (somewhat approaching ecru-drab) 

 with scarcely any trace of a yellowish tinge, and the flanks and anal 

 region lighter fawn. 



Adult females. 82.7.27.5, al., Amboina, October : Back light 

 buffy wood-brown (the colour might equally well be described as 

 bufl'y tinged with extremely light cinnamon), with a sharply 

 defined vandyek-brown dorsal stripe from nape to interfcmoral ; 

 individual hairs (outside dorsal stripe) dark brown at extreme base, 

 then buff (this colour partly showing through in the arranged fur), 

 narrowly tipped with light cinnamon. Head and nape of neck 

 nearly cream. Underparts cream-buff, flanks and anal region 

 similar hut tinged with pale fawn. — A female from Timor Laut 

 (al., 83.3.24.3) does not differ essentially in colour.
