Mammals from Peru and Bolivia. 189 
Nectomys Garleppit, Thos. 
Neacomys spinosus, Thos. 
Dr, Allen’s Inambari record for this species was quite to be 
expected, as Mr. Simons has found it both on the Perené and 
at Mapiri, on the Beni. 
Ichthyomys Stolzmanni, Thos. 
Marcapata. J. Kalinowski. 
Oxymycterus juliace, All. 
Skeleton ¢, Rio Inambari. Simons. 
It is unfortunate that Mr. Simons did not obtain a skin of 
this species for comparison with QO. d¢nca and iris; but the 
skull, which is barely adult, is not exactly like that of either, 
Oxvymycterus apicalis, Allen. 
One specimen. Santo Domingo, 13° 5! 8. and 70° W. 
1800 m. 21st July. ‘Topotype. 
This most remarkable rat is so unlike any previously 
known species of Oxymycterus that until its skull was cleaned 
I could not believe that it had been correctly placed in that 
genus; but its cranial characters confirm Dr, Allen’s judgment 
in the matter. ; 
It was at Santo Domingo that Mr. Simons found Mr. Keays 
in residence, so [ presume that it was there he collected the 
specimens described by Dr. Allen. 
Oxymycterus mimus, Thos. 
Limbane. Simons (as above). 
Akodon caliginosus, ‘Tomes. 
Marcapata. Kalinowski. 
Santo Domingo. Simons. i 
Also sent by Mr. Simons from Mapiri, across the frontier 
in Bolivia. 
Akodon boliviensis, Meyen. 
Limbane. Simons. 
This is the common olive Akodon of all the highlands of 
S. Peru. a ate 
The type locality is not in Bolivia, but near Mount Misti, 
Dept. Arequipa. My A. mollis is its lowland representative, 
and may perhaps pass into it.
