most distant relative, S. b. paraguensis. Presumably, similarities 

 between kelloggi and paraguensis are correlated with environmental 

 similarities in their respective habitats. Climatic conditions at sea 

 level, latitude 25° S., are comparable to those at high altitudes near 

 the Equator. 



Specimen examined. — One. Guachanamd, 1 (A.M.N.H.), 



SYLVILAGUS BRASIUENSIS CHILLAE Anthony 



Sylvilagus chillae Anthony, Amer. Mus. Nov. No. 55, p. 12, 1923. 

 S[ylvilagus] chillae, Hershkovitz, Occ. Papers Univ. Michigan Mus. Zool.. 

 No. 393, pp. 4-5 (Porto Velo, El Oro; comparisons). 



Holotype.— Adult female, skin and skull, A.M.N.H. No. 60511; 

 collected August 29, 1920, by H. E. Anthony. 



Type locality. — Trail from Salvias to Zaraguro, southwestern flank 

 of the Cordillera de Chilla, El Oro, Ecuador; altitude, 6,600 feet. 



Distribution. — Tropical and subtropical forests of the western slopes 

 of the Cordillera de Chilla (Cordillera Occidental), El Oro Province, 

 southern Ecuador. 



Characters. — Paler than kelloggi, more warmly colored than daulen- 

 sis. 



Remarks. — An immature specimen at hand from Porto Velo, El 

 Oro, a few kilometers south of Zaruma and in the typical region, is 

 labeled "a tame animal." Another, an immatm-e, from Arenillas, 

 El Oro, in the dry coastal region of southern Ecuador, is considerably 

 paler throughout but, presumably, nearer typical chillae than capsalis 

 of northwestern Peru. The last is very dififerent from the dark, richly 

 ochi'aceous daulensis of the coast farther north. 



Specimens examined. — Three. The type (A.M.N.H.); Porto Velo, 

 1 (A.M.N.H.); Arenillas, El Oro, 1 (C.N.H.M.).

 Ecuador north of Guayaquil, Guayas Province.

Characters. — A dark tapiti, more warmly colored than chillae, 

 slightly paler than surdaster. 



Remarks. — Doubtfully distinct from surdaster. 



Specimen examined. — One, The type (A.M.N.H.),
