PisMT PotrcHBD Mouse. 



Size very small, general appearance exceedingly mouse-Hke. 

 Pur short, soft and fine, mainly composed of the underfur. 

 General colour finely grizzled mouse-grey, the head, back, outsides 

 of limbs, and upper side of tail all uniformly of this colour, which 

 is strikingly similar to that of Mus mvsCulus. Ears of medium 

 size, laid forwards just reaching to the centre of the eye, thinly 

 clothed with short pale brown hairs. Lips and chin white ; chest, 

 belly, inner sides of Umbs, and lower side of tail like hack, but 

 rather paler, the hairs slate at their bases and pale grey at their 

 tips. Hairs of pouch pale shining grey. Hands and feet pale 

 brown ; palms and soles quite naked, the former with six pads and 

 the latter with seven, owing to the development of a minute 

 supplementary pad on the outer side of the foot halfway between 

 the pad of the fifth toe and the postero-extemal pad. Tail rather 

 shorter than the head and body, uniformly short-haired throughout, 

 its scales very small, averaging about 25 to the centimetre. Pouch 

 much more developed than is usual in the genus, its anterior and 

 lateral walls from 4 to 6 miUim. high, its posterior lower, so that 

 as a whole it opens backwards. Mammae 8. 



'Skull (PI. XXIV. fig. 8) smooth and round, muzzle short and 

 conical. Nasals narrow in front, considerably expanded behind. 

 Interorbital region smooth, its edges evenly rounded. Occipital 

 crests little developed. Anterior palatine foramina reaching about 

 to the centre of the canines. Posterior palate comparatively perfect, 

 vacuities either small or absent. Bullae small, transparent, their 

 posterior, mastoid, portion approaching their anterior in size. 



Teeth (PI. XXV. fig. 3). Upper lateral incisors minute, cylin-
