case in the fresli specimen not being materially different from 

 that in Marmosa. 



The tooth-characters are all as described in the type, and it 

 may be noted in addition that the upper milk-seeator is 

 narrower than in Marmosa, and has its inner lobe further 

 back, the tip of the lobe being behind the level of the ante- 

 rior main cusp, while it is in front o£ it in Marmosa. 



Allowing for the difference in age, I can see no reason to 

 suppose that the Yungas specimen is specifically distinct 

 from that from Pozuzo.

 notum, broadened posteriorly and obliquely sloped. Shining, 

 the head finely aciculate, thorax and abdomen with a few 

 fine scattered punctures. First dorsal segment broadly 

 depressed at the apex, the raised basal portion broadly and

 the raised apical margin ; pygidium lanceolate. Ventral 

 segments more strongly punctured, the fifth closely and 

 coarsely punctured.

This female is easily distinguished by the peculiar form of 

 the pronotum.
