Geographical d!><trih d ion. — Coast region of Peru, in the neighbor- 

 hood of Lima. 



Descrljytion. — Type, adult female. No. 39816, U.S.N.M.; Lima, Peru; 

 Walter S. Church. Upper parts light wood brown, rather tinged 

 with ochraceous, the rump and upper tail-coverts deep, dull tawny; 

 tail like the rump, l)ut darker, crossed by numerous narrow bars of 

 dark brown; wing-quills fuscous, broadly barred on exterior webs 

 with ochraceous, which on the tertials extends to both webs; wing- 

 coverts like the back, the greater and median series with bars of 

 dusky; sides of head, including the lores and a narrow, inconspicuous 

 supen^iliary stripe, pale buii', the ear-coverts with brownish admixture; 

 sides of neck wood brown like the back; entin^ lower surface buff, 

 though whitish on throat and center of abdomen, and deepening to 

 ochraceous on sides, flanks, and crissum, the last unmarked with 

 darker; lining of wing buffy white. Length of wing, 50.5 mm.; tail, 

 38 mm.; exposed culmen, 13 nmi.: tarsus, 1!».5 mm.; middle toe, 

 11 nun. 



This is a very pale form, thus resembling ((/h/can.s^ but distinguish- 

 able by reason of the brighter ochraceous of sides, flanks, and crissum, 

 and the deeper buffy suffusion of the entire lower surface. It differs 

 from T. ni. rex in ])eing lighter below and alcove, particularl}" on the 

 rump, and in having no spots at all on the crissum. A specimen from 

 Callao, Peru, is identical with the tvpe.

Tnxjlnihilrs tannerl Townsend, Pror. V. S. Nat. Muss., XIII, 1890, p. 133. 



Ti/jje locality. — Clarion Island, Kevillagigedo Islands, Mexico. 



Geoiirapliical distrlhution. — Clarion Island, Kevillagigedo Islands, 

 Mexico. 



Similar to Troglodytes! heani., but the lower back and rump arc verj' 

 little or not at all I'ufescent, and sometimes ol)scureh'^ barred with 

 dusk}'; the wings and tail are more grayish l)r<)wn; the entire lower 

 surface is dull cream color, slightly ])r()wnish on th(^ flanks. 



This species is a perfectly typical Troglodytc-i. while strangely 

 enough the wren that inhabits the neighboring island of Socorro is 

 apparently a ThryoiiKincs.^''
