ART. 7 REVISION" OF THE GENUS BASILEUTERUS — TODD 53 



Measurements.— M.q\q (three specimens) : Wing, 60-63 (average, 

 62); tail,. 44-50 (48); bill, 10-11 (10.5); tarsus, 18.5-20 (19). Fe- 

 male (two specimens): Wing, 55-57; tail, 46-47; bill. 9.5; tarsus, 

 18.5-19. 



Ra/nffe. — Humid Tropical Zone of southwestern Colombia and 

 northwestern Ecuador. 



Remarlis. — Judging from the few specimens examined, this race 

 appears to be a good one, its characters being a further extension of 

 those of B. c. chry so g aster (as compared with B. hivittatus). It was 

 described from two specimens of " Quito " make, but later records 

 go to show that it does not range so high up, and I therefore propose 

 to substitute Lita (altitude 3,000 feet), northwestern Ecuador, as the 

 accepted type locality. 



Speciinens examined. — Ecuador: "Quito," 1 (coll. von Berlepsch) ; 

 Lita, 2; Chimbo, 1. Colombia: Buenavista, Nariiio (1.200 feet), 2. 

 Total, 6.

Description. — Above, including wings and tail externally, dark 

 citrine, a little clearer and purer on the nape and the sides of the 

 head; crown with a coronal spot of Mars yellovr, inclosed between 

 two lateral stripes of velvety black, which are produced backward 

 and expanded over the nape, inclosing here a smaller spot of citrine ; 

 superciliaries citrine, their lower edge, from the nostrils to over the 

 eye, narrowlj^ pale yellow; a dusky black stripe through the eye; 

 edge of lower eyelid pale yellow ; under parts in general wax yellow, 

 the sides shaded with pyrite yelloAv; bill horn brown; feet pale (in 

 skin). 



Most of the specimens examined show citrine tipping to the feath- 

 ers of the vertex, producing a veiled effect.

 70); tail, 60-62 (61); bill, 11-12.5 (12); tarsus, 20.5-22.5 (21.5). 

 Female (four specimens) : Wing, 62-66 (64) ; tail, 55-56 (65.8) ; bill,
