neto Mammals from Bolivia, 279 



it is the specimen from " Tropical America " described in 

 1865 by Gray as '* Gonepatus nasutus^ var. 4. LichtensteinV"^ ^ 

 but this differs by its smaller size, narrower white dorsal 

 lines, white tail, naked soles, and other details. Somewhat 

 similar specimens to the latter come from Costa Rica. 



Phyllotis (?) Garleppii^ sp. n. 



General appearance very like that of one of the North- 

 American '' Grasshopper Mice " {Onychomys), an appearance 

 chiefly due to the short tail. Fur close and thick, not parti- 

 cularly long for an inhabitant of such altitudes ; hairs of back 

 about 12 niillim. in length. General colour above greyish 

 buff, finely lined with black, becoming clear buff along the 

 sides. Face rather paler, rump rather stronger buff, but no 

 special contrasts present. Eyes without darker rings. Ears 

 smaller than in other Phyllotes^ their colour not unlike that 

 of the back, except that the anterior part of the outer surface 

 is rather blacker. Hairs of under surface slaty basally, 

 snowy white terminally, the line of demarcation on sides 

 sharply marked ; on the chest the hairs are snowy white to 

 their roots. Hands and feet pure white above ; soles hairy 

 for their posterior two thirds. Tail extremely short, not 

 twice the length of the hind foot ; closely haired, pure white 

 above and below throughout. 



Skull with a very convex frontal profile, the muzzle being 

 markedly bent downwards ; nasals long, hiding the incisors 

 from above ; zygomata starting very strongly and abruptly 

 outwards, and tlien turned back almost at a right angle, front 

 edge of their anterior root much slanted and running up to 

 a very high level on the skull, so that the forehead does not 

 project above the upper anterior zygoma-root. Supraorbital 

 edges square, not ridged. Palatal foramina long and well 

 open, reaching backward to the middle of m}. 



Incisors more thrown forward than usual, very slender, 

 their narrow anterior faces pale yellow above and below. 



Dimensions of the type (an adult male) measured in 

 skin : — 



Head and body 123 f millim. ; tail 38 ; hind foot (wet) 25 j 

 ear (wet) 18. 



Skull : greatest breadth 17'8; nasals 13"4x4:; interorbital 

 breadth 3*7 ; palate length from henselion 14*2; diastema 8 7 ; 

 palatal foramina 7*2 x '2 b ; length of upper molar series 5'1 ; 

 lower jaw, condyle to incisor-tip 21.
