A molting male from La Candela agrees with one in similar plumage from 

 Fusugasug^ and therefore shows no approach toward M. corunidatiis with 

 which this species does not appear to intergrade.

(3158) Masius corunulatus Scl. 



Masius corunulatus Sci,., P. Z. S., 1860, p. 91 (Nanegal, Ecuador); Scl. & Salv,,

Masius chrysopterus beUus Habt. & Hellm., Orn. Monatsber., XI, 1903, p. 35 

 (Rio Lima, 4000 ft., w. Col.); P. Z. S., 1911, p. 1138 (Pueblo Rico, 5200ft.). 



We have found this species only in the Western Andes and lower Cauca 

 slope of the Central Andes. At Buenavista it descends as low as 1200 ft. 



The most careful comparison of eight males from western Colombia with 

 two from Nanegal (type-locality of corunulatus) and two from Gualea, 

 Ecuador, fails to reveal characters on which to base a Cauca region form. 

 Both Colombian and Ecuadorian series contain birds with "tobacco-brown" 

 and "dark red" {cf. Hellm., Gen. Av., Pt. IX, 1910, p. 16) crests. The 

 yellow of the wings averages deeper in the Colombian birds, but the dif- 

 ference at best is slight and entirely overlapped by individual variation. 

 Possibly our specimens from Gallera and Buenavista may not typically 

 represent "hellus" of the Cauca region, though we have not found in other 

 species any difference between specimens from Gallera and the Andes west 

 of Cali. Furthermore, a specimen from Las Lomitas, essentially topo- 

 typical of hellus, can be almost exactly matched with one from Gualea. I 

 detect no evidence of intergradation between this species and M. chrysop- 

 terus of the Eastern Andes.
