PTEROl'PS SUBNIGER. 167 



upper canines, p, rather large, mucli larger than m^, about twice 

 (or a little moi'e) the bulk of i„. Posterior ledges of pj and p^ well 

 developed, raised postero-externall)' into a minute cusp; a similar 

 cusp-like elevation sometimes faintly indicated iu m,. m., small, 

 subequal in bulk to i„. 



The remarkable reduction in the siiie of the teeth accounts for 

 the non-development of a sagittal crest in this species. 



Ears. — Very small, completelj' bidden in the fur ; triangular in 

 shape, outer and inner margins almost evenly converging I'rom 

 base to tip. Densely clothed with long hairs from base to tip, in 

 front and behind. 



Interfemoral. — Extremely short or scarcely developed in centre. 



Far, — Long, very dense, silky, somewhat crinkled ; semierect 

 over the whole of the upperside of the body, directed backward but 

 not closely adpressed on underparts. Length of hairs at middle of 

 back about 25, middle of mantle 2fJ, middle of belly '22 mm. 



Above, proximal half or third of forearm clothed with long, 

 dense, adpressed hairs. Fur of back extending laterally on the 

 membrane almost to a line between middle of forearm and knee. 

 Tibia long-haired to ankle ; upperside of metataKUs and phalanges 

 to base of claws with long, thinly spread hairs. Below, proximal 

 half of tibia covered with long, dense fur. 



Colour. — Ad. skin, Mauritius, B. M. 06.1.24.2. Eack and rump 

 blackish seal-bi'own ; a slight sprinkling with silvery greyish-wliite 

 hairs detectable only on close examination. In the front of the 

 back, near the mantle, the individual hairs are seal-brown at 

 extreme base, then broadly buff, tip seal-brown ; further backward 

 the middle pale-coloured portion of the hair is gradually becoming 

 narrower and more greyish, until at middle of back ifc is represented 

 only by an indistinct greyish powdering of the middle ] ortion of 

 the hair, Avhich apart from this might be described as uniform 

 seal-brown ; on the rump the pale-coloured ring is again becoming 

 more pronounced and broader, passing from approximately mouse- 

 grey to smoke-grey near the interfemoral ; all pale-coloured parts 

 of the hairs of the back and rump only detectable on separating the 

 fur. Hair on upperside of tibia pale bufiy or cream-bufty. — 

 Breast, belly, and tianks seal-brown, sparsely and inconspicuously 

 sprinkled with some long buffy hairs. Anal region next to intei- 

 femoral and fur on underside of tibia bufl'y or cream-buffv. — 

 Alantle rich orange-buff, all the hairs seal-brown at extreme base. 

 On the sides of the neck and foreneck the colour gradually darkens 

 to tawny ; extreme bases of hairs evcnwhere seal-brown. — Inter- 

 ocular space, crown, occiput, and sides of bead grizzled dark 

 brownish and greyish buiTy ; individual hairs seal-browu at extreme 

 base, then broadly cream-buffy or (jreyish creain-buffy, seal-broAvn 

 at extreme tip; the general grizzled aspect of the colour of the 

 head being duo to the fact that the seal-brown tips are too short to 

 completely conceal the paler middle portion of the hairs. Chin and 

 throat uniform seal-brown.
