open as in lockwoodi. Bullae much inflated, larger than in 

 tucunianum, nearly equalling those of lockwoodi. 



Incisors wholly white. Molars larger and heavier than in 

 tucumanum, and their laminae slightly less oblique, more 

 transverse than in that species. 



Dimensions of the type : — 



Head and body 370 mm. ; tail 301; hind foot 90; ear 

 (dry) 71 *. 



Skull : greatest length 88 ; condylo-incisive length 81 ; 

 zygomatic breadth 44 ; nasals 33*5 X 10*5; breadth of brain- 

 case 35 ; projecting upper part of bulla 5*6 x 8*5 ; palatilar 

 length 41 ; diameter of bullae at right angles to their longest 

 axis 11*8 ; upper tooth-series, crowns 21, alveoli 21*8 ; 

 greatest breadth across the two series 21*8 ; breadth of w 1 on 

 lamina 5*2. 



Hab. Cerro Casabindo, 4800 m. 



Type. Adult male. B.M. no. 19. 8. 2. 32. Original 

 number 538. Collected 20th March, 1919. 



The two specimens from the lower altitude (4000 m.) of 

 Oasabindo itself are not so buffy as the two from the Cerro 

 at 4800 m., but they are both much younger, and I put 

 down their greater greyness to this cause. 



This species is distinguishable from L. tucumanum by its 

 white incisors, all our four specimens of that animal having 

 them deep yellow, as is also the case in L. cuscus and 

 lockwoodi, its larger teeth, larger bullae, and by the yellowish- 

 buffy colour of the fur. 



10. Galea comes, sp. n. 



c?. 490, 491 ; $ . 448. Abrapampa, 3500 in. 



External characters quite as in G. boliviensis. 



Skull stout and strongly built, very much as in G. anceps. 

 Nasals running back in the centre to a point projecting con- 

 siderably further backward than the premaxillary processes — 

 more so than in the lectotype of G. boliviensis. Mesoptery- 

 goid fossae parallel-sided, their anterior edge nearly squarely 

 transverse, or notched, their general shape resembling the 

 upper half of the figure called " scutiform " by Ridgway f. 

 The same is the case in G. anceps, while in G. boliviensis 

 they are narrowed anteriorly to a V-shaped notch, not unlike 



* There is an obvious lapsus calami in the measurement given on 

 Sr. Budin's label, so I have simply measured the dry ear.
