Mammals from North Argentina. 135 



the top part of the figure named " cuneate." Bullae about 

 as in G. boliviensis, not so swollen as in anceps. 



Dimensions of the type : — 



Head and body 243 mm. ; hind foot 39 ; ear 22. 



Skull : greatest length 54 ; condylo-incisive length 48 "2 ; 

 zygomatic breadth 33 ; nasals 20 x 8*2 ; interorbital breadth 

 12 ; palatilar length 24 ; antero-posterior length of bulla 13 ; 

 upper tooth-series, crowns 13 ; breadth across m 3 15*3. 



Hah. Jujuy. Type from Maimara, 2230 m. Other speci- 

 mens from Abrapampa. 



Type. Adult female. B.M. no. 12. 12. 12. 53. Original 

 no. 25. Collected 15th March, 1912, by E. Budin and 

 presented by the Hon. N. Charles Rothschild. Eight speci- 

 mens examined. 



This Cuiso agrees with G. boliviensis in the size of its 

 bullse, but differs by the peculiarly broadened shape of the 

 choanse, which are more like those of the large-bulla species, 

 G. anceps. 



11. Dasypus nationi, Thos. 



<y . 435, 436. Abrapampa, 3500 m. 



" Quirchincho." 



So far as I am aware, no specimen of this distinct species 

 has been recorded since I described it in 1894* on an 

 example sent from Oruro to Prof. Nation of Peru, by whom 

 it was presented to the British Museum. 



The type having had quite an imperfect skull, I am glad 

 to be now able to record the skull-measurements of- an old 

 male of the species, no. 435 : — Condylo-nasal length 73 ; 

 basal length 60 - 5 ; zygomatic breadth 46; nasals 24x8*5 ; 

 interorbital breadth 18'5 ; bi-meatal breadth 45 ; palatal 

 length 42; greatest breadth of palate including teeth 16. 



These two specimens differ in the number of scale-rows in 

 the shoulder-shield, no. 436, like the type, having only three 

 rows in the centre, while no. 435 has tour. 



Both specimens are rather more hairy than the type, but 

 the latter looks somewhat worn and may possibly have been 

 in confinement.
