304 I'TEROPUS PSELAPHOX. 



distinctly concave in upper third ; tip narrowly rounded off. 

 Posterior face of conch hairy at base and along outer and inner 

 margins ; tip and median portion naked. 



Wings. — About 30 mm. apart at origin from sides of back. 



/n<e)'/e»ioraL^ Undeveloped in centre. 



Fur. — General aspect : nnusaally long, dense, rather coarse, 

 spreading on back and rump, almost erect on mantle. Shorter 

 ground-fur everywhere thickly mixed with very long, coarse hairs. 

 Approximate length of longest hairs, back 30, mantle 30, middle 

 of belly 26 mm. Width of furred area of back about 50 mm. 



Above, humerus and proximal half or two-thirds of forearm 

 thickly covered with rather long adpresscd hairs. Tibia thickly 

 clothed. Feet distinctly haired to base of claws. Iiiterfemoral 

 along inner side of tibia almost concealed by overhanging long 

 hairs. 



Eeneath, proximal half of forearm thinly haired. Antebrachial 

 membrane, and lateral membrane along outer side of forearm and 

 between humerus and femur, clothed with woolly hairs. Proximal 

 half or two-thirds of tibia thickly haired. 



Colour. — Adults (three skins ; 94.7.3.1-3) : Prevailing colour 

 above and beneath almost typically seal-brown, with a slight 

 blackish-maroon gloss ; underparts not appreciably paler ; head 

 and mantle not differing from back ; rump generally similar to 

 back, sometimes slightly washed with dark vandyck-brown. Back, 

 rump, breast, belly, and flanks sprinkled with glossy silvery greyish- 

 white (on the rump sometimes more huffy-white) hairs, the amount 

 of sprinkling individually variable, always conspicuous, but never 

 obliterating the general dark aspect of the coloration ; sprinkling 

 on breast and belly usually rather thicker than on back. Seal- 

 brown of mantle thinly varied with short silvery greyish-white tips 

 to the hairs ; on the sides of the neck the pale hair-tips are longer, 

 forming an ill-defined patch on each side ; foreneck similar to breast. 

 Head seal-brown, more or less sprinkled with silvery- white or buffy- 

 white hairs (or tips to the hairs), particularly on sides of head. 



Two immature individuals (male and female, practically full- 

 grown : 5.1.4.1-2) have the general dark colour of the pelage 

 conspicuously washed with dark vandyck-brown, especially on 

 back, thighs, and tibiaj ; pale sprinkling inconspicuous on upper- 

 side, more distinct on underparts (particularly in $ ) ; ill-defined 

 lateral neck-patches as in adults. It is doubtful whether the 

 vandyck-brown tinge of the colour is really due to the immature 

 age of these specimens, rather than indicative of an individual 

 variation occurring also in adults.
