Biilhe small, nasals unusually narrow and pointe<l beliinJ, 

 ears and tail short, all a^ contpared witli tlie next species. 



Tlie bulla) are about \ nun. in loni^ltMilinal diameter as 

 measured alontj a line parallel witli tlio middle line ot' tlio 

 skull. lOars as measured by collectors 21 or 22 mm. in 

 ieiii^tli. 'Tail usually 100-110, rarely llf) mm. In two very 

 old specimens, however, nos. 341) and 3»»4, of whose deter- 

 mination I do not feel (piite sure, these dimensions are 

 exceeded, the ears and tail reaching to lengths normal in

G. P/if/llotis ricariiulus, sp. n. 



c?. 332, 355, 36G, 372 ; ? . 346, 351, 373. 

 Like P. tucumanus, but with larger bulloe, larger ears, and 

 lonj^er tail. 



Size about as in tucumanus. General colour above olive- 

 grey, varying, as do all the species of P/ii/llolis, in the extent 

 to which bully is suft'use 1 in the colour. Sides, wlien in 

 adult pelagi", with a well-inarkfd butfy band running from 

 cheeks to base of tail. Under .surface soiled grey, the hairs 

 very dark slaty basally, broadly washed with whitish or 

 buffy whitish, h^ars decidedly longer than in tucumanus, 

 but much smaller thaii in vaccarum or woIffsoJuiiy their pro- 

 ectote blackish, the rest grey. Hauils and feet |)ure white. 

 Tail longer and more heavily pencilled than in tucumanus, 

 its length rarely less than 130 mm. ; blackish proxiuially and 

 black terminally above, white below. 



Skull with the tuisals not so markedly narrowed behind as 

 in tucumanus. Supraorbital edges sharply square, not ridged. 

 Palatal foramina reaching to the level of the first lamina of 

 vi\ Buihe comparatively large, distinctly larger and more 

 fully iiiflateil than in tucumanus^ though smaller than in 

 vacoarum, their antero-posterior length on a line parallel with 

 the n)iddle axis of the skull 5 mm. or n)ore. Molars averaging 

 smaller than in tucumanus, though rather variable. 



Dimensions of the type : — 



Head and body 112 mm.; tail 145; hind foot 26; 

 ear 23. 



Skull : greatest length 30 ; condylo-incisive length 27*5 ; 

 zygomatic breadth 15b; nasals 12'5; interorbital breadth 

 4*2 ; breadth of brain-case 14 ; palatine foramina 7*2 ; post- 

 foraminal palate 5*3 ; bullre (measured as described above)

Although undoubtedly closely allied to P/i. tucumanus, 

 this species may be distinguished by its longer ears, its longer
