Previously a few specimens had been obtained by Mf. J. 

 Kalinowski at Marcapata, lower down the Inambari, and by 

 including these, the species recorded by Dr. Allen in 

 Mr. Keays's collection (omitting the Larjldium) , and those 

 now received from Mr. Simons, the number of Inambari 

 mammals is raised from eighteen to twenty-seven. 



T.ngothrix sp. (probably L. Humboldt i). 



A number of skulls. Marcapata. J. Kalinowski. 



< ehus fatuellus peruanus, Thos. 



Marcapata. Kalinowski (as above). 



Alouatta nigra^ Geoff. 



Myotis sp. 



Xyctinomus sp. 



Saccopteryx sp. 



Rio Inambari. Simons. 



Nasua montana^ Tschudi.

These are the first specimens assignable to this rare species 

 that the Museum has received. Though from the same 

 locality, they differ remarkably from each other in their 

 general colour, one being comparatively rufous and the other 

 more or less straw-coloured. 



The species appears to replace in the Peruvian Andes the 

 peculiar small-toothed iV. olivacea, Gray, of the highlands of 

 Ecuador, Colombia, and Venezuela. It is probably l3r. Allen's 

 " Xtisiia nasua^ L.'' 



Sciurus cestuatis cnscinus, Thos. 



$ $ , Rio Inambari, IGth and 19th July. 



These specimens quite agree with the type, except that 

 their feet are rather less yellow. In a nice series sent by 

 Mr. Simons from Mapiri, however, there is considerable 

 variation both in the colour of the feet and of the belly, the 

 latter part being almost white in .some specimens. 



Jfhipidomys phceotis, Thos. 



Segrario. Simons (as ab'^ve).
