Mammals from North Argentina. 129 



accurately to work out the distribution of the different forms *. 



The most striking novelty is the new Abrocoma, a genus 

 not previously known from Argentina. 



In fulfilment of my promise of further information on the 

 subject, I may record here that the locality " Otro Cerro," 

 where the collection was obtained of which I gave an account 

 in the May ' Annals ' f, proves, after all, to be in the Province 

 of Catamarca. Sr. Butlin was thus right as to the Province, 

 but wrong as to the distance and direction from Chumbicha, 

 Otro Cerro being really about 18 kilometres N.N.W. of 

 Chumbicha, and just to the south of Poman. 



Correction is therefore needed as to the Province for all the 

 species then described.

* The following new Euneomys, coming from the same general 

 region as the present collection, and, in fact, from the same locality as 

 the type of the new Galea, may be conveniently described here : — 



Euneomys {Auliscomys) leucurus, sp. n. 



Allied to E. sublimis, but larger. 



Size intermediate between those of E. pictus and sublimis. Colour 

 not very exactly definable, as the available specimens are either in 

 spirit or have recently been skinned out of it, with resultant discolora- 

 tion. The general tone, however, appears to be somewhat as in sublimis, 

 but more drabby or greyish ; hairs of under surface slaty, broadly washed 

 with pale buffy. Hands, feet, and tail white, a very faintly marked 

 narrow darker line perceptible along the top of the latter. 



Skull considerably larger than that of sublimis, but similarly built ; 

 not bo broad and stout as in boliviensis and pictus. Zygomatic plate 

 rather narrow. Palatal foramina long, reaching the level of the middle 

 root of m\ Bullae small, proportionally as in sublimis, smaller than in 

 micropus, much smaller than in pictus and boliviensis. 



Dimensions of the type (measured on the spirit-specimen, which is 

 probably somewhat contracted) : — 



Head and body 102 mm. ; tail 58 ; hind foot 21-3 ; ear 20. 



Skull : greatest length 305 ; condylo-incisive length 29 ; zygomatic 

 breadth 16-3; nasals 11*7; interorbital breadth 4; breadth of brain- 

 case 12'8 ; palatilar length 15 ; palatal foramina 7'7 ; antero-posterior 

 length of bulla 4*7 ; upper molar series 5"7. 



Hab. La Lagunita, Maimara, Jujuy. 



Type. Adult female in spirit. B.M. no. 19. 7. 10. 3. Collected by 

 E. Budin. Five specimens examined, two of them quite young. 



As shown by its small bullae, this species is clearly most closely allied 

 to E. sublimis, but is readily distinguishable by the greater size of its 

 skull.
