ART. 7 REVISIOIT OF THE GENUS BASILEUTERUS TODD 33 



that I have no alternative but to separate them under another name, 

 given in honor of Dr. Frank M. Chapman, in recognition of his 

 excellent revisionary work on this genus. 



Specimens examined.— Pern: Chaupe (6,100 feet), 4; Tambillo, 2. 

 Total, 6. 



BASILEUTERUS CORONATUS NOTIUS, new subspecies 



Basileuterus coromtus (not Myiodioctes coronatus von Tschudi) Chapman, 

 Bull. Amer. Mus. Nat. Hist., vol. 55, 1926, p. 601, part (Locotal and 

 Roquefalda, Bolivia). 

 Type.—^o. 85,521, Collection Carnegie Museum, adult "male"; 

 Yungas de Cochabamba, Bolivia, July 10, 1921; Jose Steinbach. 



Suhspecific c liar act er-s.—Similsir to B. coronatus coronatus of Peru, 

 but rather smaller; upper parts, etc., darker, less brownish, more olive 

 green; under parts with more pyrite yellow shading on the breast 

 and sides, giving a generally darker effect. 



Measurements.— Male (two specimens) : Wing, 6T-71; tail, 59-60; 

 bill 115; tarsus, 21.5-22. Female (four specimens): Wing, 60-65 

 (average, 63); tail, 53-56 (54); bill, 10.5-11.5 (11); tarsus, 



20.5-23 (22). 



Range.— SuUropical Zone, eastern slope of the Andes of Bolivia. 



Remarks.— This is a readily distinguishable race, in which the 

 upper parts are darker olive green even than in the Colombian form, 

 and the coronal spot is also darker. It appears to be confined to the 

 Subtropical Zone on the eastern slope of the Andes in the Yungas of 

 Balivia, so far as known at present. In addition to the four speci- 

 mens in the Carnegie Museum and the American Museum of Natural 

 History, I have examined five others in the von Berlepsch Collection, 

 deposited in the Frankfort Museum in Germany. None of these 

 have been recorded in print before; in fact the species was not known 

 to range farther south than Peru. The specimen selected as a type 

 is almost certainly wrongly sexed. 



Specimens examined.— BolWidi : Yungas de Cochabamba, 2 ; Loco- 

 tal (5,800 feet), Cochabamba, 1; Roquefalda, Cochabamba, 1; Que- 

 branda Honda, 5. Total, 9.
