Description. — Pileum with two lateral stripes of black, reaching to 

 the nape, and inclosing a median stripe of olive buff, which is more 

 or less tinged with Mars yellow on the vertex, appearing on the bases 

 of the feathers ; superciliaries, chin, and subociilar region olive buff ; 

 transocular stripe dusky black ; sides of the neck, and upper parts in 

 general, including the wings and tail externally, neutral gray, the 

 back often with an olivaceous wash; wing-coverts sometimes with 

 faint whitish tips; under parts bright yellow (lemon chrome), the 

 sides with more or less wash of sulphine yellow, the crissum paler and 

 more whitish; bend of wing yellowish; under wing-coverts white; 

 " iris brown ; feet pale brownish flesh-color ; bill black, dark horn 

 below." 



Juvenal plumage (No. 89,865, Collection Carnegie Museum, July 

 6) : Above dull mouse gray, almost uniform; throat and breast simi- 

 lar but duller and paler, with a yellowish tinge, passing into pale 

 buffy yellow posteriorly. 



Measurements. — Male: Wing, 5(>-61 (average, 58.5); tail, 51-57 

 (53.5) ; bill, 10.5; tarsus, 18.5-20 (19). Female: Wing, 53-57 (54) ; 

 tail, 49-52 (50.5) ; bill, 9.5-10.5 (10.3) ; tarsus, 17.5-19 "(18.3). 



Range. — Subtropical Zone, Andes of Colombia and Venezuela. 



Remofrks. — In general, Basileuterus cahanisi would seem to be a 

 bird of the Subtropical Zone, but it drops down to as low as 1000 

 feet in some places. It is certainly a close ally (and probably a 

 derivative) of B. auricajnllus oUvascens, which occupies the Tropical 

 Zone in the Orinoco Valley and the northeastern part of Venezuela, 

 reaching also to Trinidad. Their respective ranges approximate 

 each other at certain points, but are not known to overlap. I do not 

 consider them conspecific, however. Count von Berlepsch's type 

 series came from San Esteban and Puerto Cabello (probably actually 

 higher up), Venezuela, but he was mistaken in placing previous Ven- 

 ezuelan and Trinidad records for B. " verimvorus " under the same 

 head. The species was presently reported from Bucaramanga, Co- 

 lombia, and more recently has been traced to the Central and West- 

 ern Andes of the same country by Doctor Chapman and Mr. Car- 

 riker. Our specimens from these parts are quite indistinguishable 

 from those coming from Venezuela, all having the crown showing a 

 more or less decided spot of Mars yellow. Three specimens in the 

 von Berlepsch collection, however, lack any of this color on the 

 crown, and are thus scarcely to be told from the race of the Santa 

 Malta Mountains, B. c. indignus.
