Holotype. — Skin, Civico Museo di Milano; collected between July 20 

 and October 26, 1847, by Gaetano Osculati. 



Type locality. — "Habitat varum in sylvis Quixos.^' The "Cantoni 

 de Quixos" as indicated on the map prepared by Osculati (supra cit.) 

 comprises the region embraced by the upper Rio Napo and its affluent, 

 the Coca. Anciently, the province of Quixos extended to the Amazon 

 but in modern maps the term Quixos (or Quijos) is restricted to the 

 right branch of the upper Rio Coca. Osculati {op. cit., p. 123) first 

 mentioned the tapiti in connection with his three-month sojourn in 

 the area around Puerto Napo. He trapped tapitis there and, inci- 

 dentaUy, noted that upon the advent of a jaguar they would seek 

 refuge near huts of natives. With place of capture of the original 

 specimen of defilippi known, the type locality may be restated as 

 Puerto Napo, at head of navigation on the Rio Napo, eastern Ecuador; 

 altitude 457 meters.
