Size smaller than in B. cwniculus, hut the hind feet rather longer 

 in proportion. Fur woollier in texture than in the other species, the 

 woolly underfur thicker and longer. DetaUs of coloration on body 

 and limbs quite as in B. euniaulus, but the general tone rather more 

 yellowish or fawn. Tail coloured like the body for its basal third, 

 then gradually darkening above and the hairs lengthening until 

 there is, on the terminal third, a distinct black crest, the longest 

 hairs of which are upwards of an inch in length ; underside short- 

 haired, white ; a few hairs at the extreme tip white,' but these very 

 inconspicuous, hidden by the longer black hairs. 



Skull smooth and rounded, with a broad conical muzzle. Nasals 

 (PI. XIV. fig. 3) short and broad, their least from one half to three 

 fifths their greatest width, the latter going only about once and 

 three quarters into their length ; their sides but little curved, and 

 their posterior margin straighter across and less curved than in 

 B. cuniculus; but more than in B. penicillata. Interorbital space 

 broad and smooth, its edges square or slightly rounded. Palatal 

 foramina very short. Posterior palatal vacuities extending to about 

 the middle of m.* BuIIeo (PI. XIV. fig. 4) smooth and transparent, 

 but low and but little inflated, their most prominent point only 

 about 8 millim. below (in the natural position) the condyloid sur- 

 face of the glenoid fossa.

 perfectly straight antero-posteriorly, its postero-internal talon dis-
