53. ODOCOILEUS PERUVIANUS Gray, 



Six specimens as follows : 



Ollantaytambo, 3 males and 1 female (Nos. 194300, 104304-5, 

 194299). 



Chospyoc, Huaracondo, 1 male (No. 194301). 

 Paso Panticalla, 1 female (No. 194306). 



54. MAZAMA AMERICANA WHITELYI Gray, 



Female, Uvini, Eio Cosireni (No. 194308). 



This is clearly Tschudi's Cervus imfus, but on geographical 

 grounds it may be provisionally considered as subspecifically distinct^ 

 from the Guianan and Brazilian form, to which that name, synony- 

 mous with americanus, properly belongs. 



The type skull of Gray's Coassus lohitelyi, however (B. M. No. 73. 

 6. 27. 2), coming quite from this region, appears to me to be referable 

 to this larger Brocket, and not, as Lydekker has placed it, to the 

 smaller Masama tschudii, the Cervus nemorivagus of Tschudi. 



Unfortunately that type skull is without skin and quite young, 

 while Mr. Heller's example is old, and we have no Peruvian speci- 

 mens connecting the two. An absolute identification must therefore 

 await further material. 



The hairs on the nape of this specimen are not reversed, and the 

 skull measures 204 mm. in condylobasal length; tooth-series (worn) 

 63 mm. The anterior palatine foramina are no less than 37 mm. in 

 length. 



55. MAZAMA, species. 



Imperfect skull of a male from Santa Ana, 3,480 feet (No. 194307). 

 Collected by E. C. Erdis. 



This skull (found on ranch of, and presented by, Alberto Duque) 

 consists only of the.frontals and brain case, without teeth, and is not 

 certainly determinable. It seems, however, to indicate the presence 

 in this region of a small Mazama of the rufina-hHcenli group, as it 

 appears too small to belong to M. tschudii., at least if that species is 

 really as large as M. simpUcwomls, of which it is said to- be the 

 Peruvian representative. 



56. HIPPOCAMELUS ANTISIENSIS D'Orbigny. 



Male and female from Ollantaytambo, 14,000 feet (Nos. 194298,. 

 194303). 



57. LAMA HUANACHUS CACSILENSIS Lonnberg. 



Two males from La Eaya Pass, 16,000-17,000 feet (Nos. 194292^ 

 194294). 



All the guanacos of the highlands of Peru and Bolivia may ap-- 

 parently be distinguished from those of Chile and Patagonia by
