coppery or ciniintnon (Dr. lliiiile speaks of the colour a3 

 " bronze "). Uiid'-r surface paler brown, the tips of the hairs 

 becouiiii^ ahnost white in the pubic region. 



Fur above not extending on to arms or wing-membranes, 

 though there are a few fine hairs on the tliumbs ; l)ut the 

 legs are clutlied as far as the knee, the backs of the feet are 

 finely hairy, arid the basal half of the interfemoral is thinly 

 covered with fine and inconspicuous hairs. Below the wing- 

 membranes are finely clothed nearly as far outwards as a lin? 

 from the elbow to the knee, but the interfemoral membrane is 

 more nearly naked than above. No trace of an interfemoral 

 fringe. 



Ears large, much larger than in Vespertilio, hwi not so large 

 as in Plecotus, Otonj/cteris, or Ilisliotus ; not connected across 

 the forehead with each other. Inner margin with a distinct 

 basal fold, ending below in a narrow lobe; its basal third is 

 strongly convex forward, so that the basal line is at right 

 angles to the upper two thirds, which are very slightly con- 

 vex and pass gradually into the rounded tip ; outer margin 

 nearly straight above, slightly convex below; antitragus low, 

 half-oval, marked by a distinct notch behind. Tragus un- 

 fortunately damaged in the type on both sides, but enough is 

 left to show that it is long, broad at base, with a slightly 

 concave inner margin and a broadly rounded tip. 



Wings of normal Vespertilionine proportions, the meta- 

 carpals of the thinl, fourth, and fifth digits approximately 

 equal in length. Insertion of wing-membrane at base of the 

 digits, 80 far as can be made out in the dry skin. Culcar 

 reaching about halfway towards the tip of the tail ; post- 

 calcaneal lobule present, but very narrow. Tip of fourth 

 finger T-shaped, or even slightly sjjatulate. Membranes and 

 ears uniformly brownish grey, except that the wing-membrane 

 from the tip of the fifth finger to the ankle is edged with 

 whitish. 



Skull very thin and papery, long and narrow, low, smooth, 

 and scarcely ridged at all. Nasal notch comparatively 

 shallow. Intertemporal region not strongly constricted, the 

 intertemporal but little less than the interorbital breadth. 

 Palatal notch penetrating to the level of the middle of the 

 canines. Palate narrow, the greatest breadth across the outer 

 corners of rn.^ going nearly three times in the total length of 

 the skull ; its posterior part produced behind the molars a 

 distance equal to the combined lengllis of />.* and ;/j.^ 



Uj)per incisors slightly convergent, of abotit the same 

 relative proportions as in the iSerotine, the inner one long, 

 with a secondary postero-external cusp near its tip and a small
