212 On small Mammals from North-western Patagonia. 
Skull, as compared with specimens from Cordova taken 
provisionally to represent G. leucoblephara, more heavily 
built, though with narrower interorbital region. Palatal 
foramina short. Mesopterygoid fossa broadly rounded ante- 
riorly, the palatine level with the main inner re-entrant angle 
on m®, In the Cordova specimens the fossa is continued 
further forward, and is narrowly pointed anteriorly. Bullee 
comparatively small, scarcely larger than in the otherwise 
much smaller G. b. (ittoralis, 
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 ; 
palatilar length 25; palatal foramina 4°2; greatest hori- 
zontal diameter of bulla 14 ; upper molar series 12. 
Hab. 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 littoralis, and its more widely open choane distinguish 
it from leucoblephara. It has smaller bulle than the still 
more northern forms of Bolivia.

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 already 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. Budin’s specimens with Philippi’s species is 
quite natural. 
Of this genus the Museum previously possessed the type 
of Dromiciops glroides from Chiloe and an individual from 
Temuco presented in 1908 by Mr. R. M. Middleton. 
“ T 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.”"—/. B. 
A most acceptable addition to the Museum collections.
