These specimens no doubt represent S. a. chimbanus Cabrera 

 (Trans. Mus. Cien. Nat. Madrid, Zool. Series, No. 9, 1913), but as. 

 I am unable to appreciate the difference between the two forms and 

 have no typical material of either for comparison, I prefer to refer 

 the specimens to Thomas's *S. andinus. 



"These cottontails were found, as we rose from the Chimbo River 

 valley up the slopes, 500 to 1,000 feet above the town of Chambo. 

 They frequented the brush-grown pastures in similar situations to those 

 frequented by our cottontails of the United States, only they kept more 

 closely to the bushes and were not found in the open pastures. They 

 seemed to range from that point no lower, but to reach up the slopes 

 into the paramo, at an elevation of 12,000 to 13,000 feet, but we 

 secured none in the paramo region, abundant as they evidently 

 were by their tracks and droppings in the thick tussock grass. We 

 also saw several on the paramo of Mount Pichincha, above Hacienda. 

 Garzon, but were fated to secure no specimens. None were seen in 

 this locality below the paramo, viz., 11,000 feet, approximately. 

 It is quite possible that the paramo rabbit is distinct from the 

 animal of the templada, at least subspecifically, or that there are 

 two species, not distinguisliable at a distance by a field observer."'

15. Mazama americana (Er&l). 



Moschus americanus Erxleben, Syst. Regni. Anine, vol. I, p. 1777. 



One female specimen (12,730, Coll. A. N. S. Phila.) obtained at 

 the junction of the Chanchan and Chaguancay Rivers on the lower 

 western slope of the Andes, February 27, 1911. 



Length 1,050 mm., height at shoulder 600, height at rump 715,. 

 tail 160, ear 115. 



Mr. W. H. Osgood has revived Erxleben's name for M. nemo- 

 rivagus (Field Museum, Nat. Hist. Puhl., No. 155, vol. X, p. 43, 1912)
