212 0)1 small Mammals from North-western Patagonia. 



Skull, as compared -with specimens from Cordova taken 

 provisionally to represent G. leucoble/>hara, more heavily 

 built, though with narrower interorbital region. Palatal 

 foramina short. Mesopterygoid fossa broadly rounded ante- 

 riorlv, the palatine level with the main inner re-entrant angle 

 on 7)1^. In the Cordova specimens the fossa is continued 

 further forward, and is narrowly pointed anteriorly. Bullte 

 comparatively small, scarcely larger than in the otherwiae 

 much smaller G. b. littoralis. 



Dimensions of the type: — 



Head and body 215 mm. ; hind foot 38 ; ear 24. 



Skull : greatest length 55 ; condylo-incisive length 48*5 ; 

 zygomatic breadth 32 ; nasals 20 ; interorbital breadth 9'5 ; 

 pahitilar length 25 ; palatal foramina 4'2 ; greatest hori- 

 zontal diameter of bulla 14 ; upper molar series 12. 



Hah. and type as above. 



The present is the furthest southern record for the genus 

 Galea, the next northwards being that of G. boliviensis 

 littoralis trom Bahia Blanca. The present animal is larger 

 than littoralisj and its more widely open choange distinguish 

 it from leucoblephara. It has smaller buUaj than the still 

 more northern forms of Bolivia.

? . 126, 143. Pilcaiieu. 1400 m. 

 " Caught among burrows out on the fields." — E. B. 



20. Dromiciops australis, Phil. 



cJ. 71; ?. 111. Beatriz, Nahuel Huapi. 800 m. 



The type-locality of Philippi's Didelphys australis appears 

 to have been in the neighbourhood of Union, Valdivia, some 

 150 kilometres north-west of Nahuel Huapi, on the Chilian 

 side of the Cordilleras. But, as alreadj^ mentioned, the 

 mountains in this region do not form an unbroken barrier, 

 and Nahuel Huapi itself makes a gap in them, so that the 

 identity of Sr. 15udin's specimens with Piiilippi^s species is 

 quite natural. 



(Jf this genus the Museum previously possessed the type 

 of Dromiciops gliroides from Cliiloe and an individual from 

 Tenmco presented in 1908 by Mr. P. hi. Middleton. 



" 1 was much pleased to obtain this striking little animal, 

 which seems to be very rare. It was, like other things, 

 caught among the roots of fallen trees." — E. B. 



A most acceptable addition to t4ie Museum collections.
