62 MR. C. BODEN KLOSS ON 



raceous-buff and blackish : sides of head and body rather more 

 ochraceous buffy. Pelage throughout neutral grey at base. Sides 

 of muzzle, limbs beneath and under-parts greyish-white, fairly 

 clearly margined. Hands and feet white. Tail dark above and 

 pale below, the hairs clothing it in agreement. 



There appear to be three pairs of pectoral mammae : the 

 inguinal number is not ascertainable. 



Skull and teeth. Skull long and narrow : braincase markedly 

 pear-shaped. 



Nasals extending slightly beyond the premaxillaries and the 

 anterior edge of the orbital spaces, rounded anteriorly, truncate 

 posteriorly. 



Supraorbital edges sharply angular but without ridge or 

 bead. Anteorbital plates very angular, the apex slightly overhang- 

 ing the base and the backward flexture very abrupt : a very small 

 excrescence at the anterior foot, in no way approaching in size or 

 shape the masseteric knob of Mils. 



Dorsal profile of skull regularly curved, crown but little 

 flattened. Palatal foramina long and almost parallel-sided, but their 

 greatest combined breadth in front of their mid -length, truncate 

 posteriorly and terminating in line with the anterior edges of the 

 crowns of the first molars, considerably within the roots, which are 

 exposed : toothrows converging posteriorly. 



Mesopterygoid space narrow and diverging slightly posterior- 

 ly, scarcely reaching the level of the last molars. 



Size and dilation of bullae normal, as in Mus. 



Upper incisors nearly upright, as in L. p. gairdneri. 



Measurements. See table postea. 



Type. Adult female with very worn teeth (skin and skull)
