iRT. 7 REVISION OF THE GENUS BASILEUTEEUS TODD 47 



and postocular spot dark olive gray ; auricular region like the back ; 

 under wing-coverts yellowish white; bill black; feet pale brown (in 

 skin). 



Measurements. — Male (eight specimens) : Wing, 68-76 (average, 

 72); tail, 60-69 (64); bill, 10.5-12 (10.8); tarsus, 20-21.5 (21). 

 Female (two specimens): Wing, 65; tail, 59-62; bill, 11; tarsus, 

 20.5-21. 



Range. — Humid Temperate Zone of the Andes, in Venezuela, 

 Colombia, and Ecuador. 



Remarks. — In its reduced ninth primary this species approaches 

 Myiothlypis (in which, indeed, it was actually placed by Bonaparte 

 in 1850), but otherwise is best referred to Basileicterus, although^ 

 aberrant in coloration. It is most nearly related to B. signatus and 

 B. fiaveolus.^ but while these two are species of the Subtropical Zone 

 and the Tropical Zone, respectively, B. luteoviridis (as a species) is 

 rather more characteristic of the Temperate Zone of the Andean 

 system. The typical race occupies the strip of Temperate Zone 

 stretching from Venezuela and Colombia into Ecuador, on the upper 

 slopes of the Andes.

/Suhspecific characters. — Similar in size and general coloration to 

 B. luteoviridis luteoviridis, but superciliaries much wider and more 

 distinct, as well as brighter yelloAv (empire yellow) ; lores and post- 

 ocular spot darker (as in B. signatus).
