Article III. ON A FURTHER COLLECTION OF MAM- 

 MALS FROM SOUTHEASTERN PERU, COLLECTED 

 BY MR. H. H. KEAYS, WITH DESCRIPTIONS OF 

 NEW SPECIES. 1 



By J. A. ALLEN. 



The Museum has just received a third collection of mammals 

 made by Mr. H. H. Keays, at the Inca Mines, near Juliaca, 

 southeastern Peru. This collection contains nearly all of the 

 species previously received from Mr. Keays, and eight ad- 

 ditional, three of which appear to be undescribed. The species 

 additional to the former list are nearly all from other localities, 

 as San Antonio, Osila, and Tirapata, situated at much higher 

 altitudes than the Inca Mines. 



In this connection it is necessary to correct a misleading state- 

 ment in my former paper in respect to the locality where the 

 principal part of Mr. Keays's first collections were made. Mr. 

 Keays's post-office address was Juliaca, and through lack of ex- 

 plicit information, it was inferred that the Inca Mines, where he 

 collected, were in the immediate vicinity of Juliaca. In a later 

 letter Mr. Keays informs me that the Inca Mines are situated 

 about 200 miles northeast of Juliaca, on the east side of the 

 Andes, on the Inambary River, a tributary of the Amazon, and 

 at a much lower altitude than Juliaca. The altitude and geo- 

 graphical position were correctly given in the former paper, but 

 in place of Juliaca, in the introduction and for the type localities, 

 read Inca Mines. San Antonio and Tirapata have an altitude 

 of 12,000 to 16,000 feet. 



The species not recorded in the former list are indicated by a 

 star prefixed to the number. All the external measurements 

 given are the collector's measurements from the fresh specimens, 

 except when otherwise stated.
