Characters. — Palest of known forms of Peruvian tapitis; paler than 

 kelloggi and andinus of Ecuador. 



Bemarks. — Tapitis from across the divide in the Amazonian drainage 

 area of northern Peru are darker, more warmly colored and referable 

 either to kelloggi or to the race described below. 



Specimens examined. — Three. The type (B.M.); Hacienda Lla- 

 gueda, Libertad, 2 immatures (C.N.H.M.). 



SYLVILAGUS BRASIUENSIS PERUANUS. new subspecies 



Sylvilagus defilippii [sic], Osgood (nee Cornalia), Publ. Field Mus. Nat, Hist., 

 zool. ser., vol. 10, p. 171, 1914 (Moyobamba, Amazonas). — Thomas, Ann, 

 Mag. Nat. Hist., ser. 9, vol. 19, p. 371, 1927 (Yurac Yacu, San Martin); 

 vol. 20, p. 605, 1927 (Tingo Marfa). 



Sylvilagus defilippi, Anthony (nee Cornalia), Amer. Mus. Nov. No. 55, p. 11, 

 fig. 3B, 1923 (Moyobamba). 



[?]Sylvilagiis capsalis, Thomas, Ann. Mag, Nat. Hist., ser. 9, vol, 18, p. 167 

 (part; Tambo Ventilla, San Martfn), p. 399 (Corosha, Ainazonas; 10 miles 

 northeast of Chachapoyas, Amazonas), 1926. 



Holotype. — Adult female, skin only, C.N.H.M, No, 24143; collected 

 October 17, 1922, by Edmund Heller. 



Type locality. — Tingo Maria, Rio Huallaga, Huanuco, Peru; 

 altitude, approximately 700 meters. 



Distribution. — Upper Rio Huallaga drainage basin, Peruvian Andes. 



Characters. — A warmly colored Andean race, with more ochraceous 

 and less black throughout, than inca and defilippi. 



Coloration of holotype. — Back Ochraceous-Buff lined with dark 

 brown, rump Ochraceous-Tawny ; sides paler than back; rostrum 

 Ochraceous-Orange thinly lined with black; back of crown and outer 

 anterior surface of basal one-third of ear mixed buft'y and ochraceous, 

 terminal portion of outer surface of ear dark brow^l. Supraorbital 

 patch buffy, a dark brown patch behind orbit, a paler one beneath; 

 cheek Warm Buff; upper surface of foreleg Ochraceous-Orange, of 

 thigh Tawny, of hind foot Ochraceous-Buff. 



Measuremrnts of holotype (taken from the dry skin). — Total length, 

 380; tail, 30; hind foot, 70; ear, from notch, 50. Collector's measure- 

 ments on label, 300, 10, and 80, respectively, are obviously inaccurate. 



Remarks. — Comparison with tapitis from eastern Ecuador shows 

 indisputably the untenability of the name defilippi for the northern 

 Peruvian form here called 2)eruanus. A subadult from Moyobamba, 

 San Martin, provisionally assigned to peruanus is much less warmly 

 colored than the type, its back more heavily lined black. It differs 

 even more widely from defilippi to which it was provisionally referred 

 by Osgood {supra cit.). 



Specimens examined. — Eight. The type (C.N.H.M.) ; Moyobamba, 

 1 subadult, 6 immatures (C.N.H.M.).
