ABT. 7 BEVISIOIsr OF THE GENUS BASILEUTEEUS TODD 45 



Female (eight specimens) : Wing, 57-61 (59.5) ; tail, 55-59 (57) ; bill, 

 10-11 (10.7) ; tarsus, 22.5-23.5 (23). 



Range. — Subtropical Zone, Andes of Peru, from Junin southward 

 to the Urubamba Valley. 



Remarks. — This form was described as a distinct species, but has 

 been reduced to a subspecies of B. Jutecwirldis by Doctors Hellmayr 

 and Chapman. It differs from B. luteoviridis in its markedly smaller 

 size, much duller coloration throughout, and paler feet. Moreover, 

 while B. luteoviridis is a representative form of the Temperate Zone 

 in the Andes, B. signatus belongs to the Subtropical Zone. Both 

 forms occur in the Urubamba Valley in Peru at their appropriate 

 and respective elevations, as Doctor Chapman remarks. Convincing 

 evidence of their specific distinctness is now forthcoming in the 

 shape of perfectly typical examples of both which have been taken 

 at Rumicruz, Junin, Peru, at an elevation of 9,700 feet, by one of 

 the collectors for the American Museum of Natural History. The 

 type specimen of B. signatus., now before me, was collected by Kali- 

 nowski at Idma, above Santa Ana, in the Urubamba Valley ; it agrees 

 well with the good series from Peru now available. 



S'pecinnens examined. — Peru : Idma, above Santa Ana, 1 (type) ; 

 San Miguel Bridge, Urubamba Canon, 6; Santa Rita, Urubamba 

 Canon, 4; Torontoy (7,800 feet), Urubamba Canon, 2; Inca Mine, 

 2; Chelpes, Junin, 1; Rumicruz (9,700 feet), Junin, 3. Total, 19.
