50.2 Mr. P. R. LoTve — Observations 



Ecuador — Gualaquiza, Esmeraldas, Zamora, Santa Rosa, 

 Naiiegal (coast districts), Quito, Intaj, Saravacu (moun- 

 tains) ; and whether from the eastern or western slopes of tlie 

 Andean system — all agree in being darker and more richly 

 coloured than specimens from Mexico. Thus the upper 

 parts exhibit a darker and browner tint than in C. mexicana 

 (olive-grey), the pileum is not so strongly contrasted with 

 the mantle, and the rump is yellow with a faint olive tinge, 

 and even brighter tlian in C. columbiana. The yellow of 

 the under jiarts is also strikingly richer and deeper, Avith a 

 tinge of ochraceous in some seven or eight specimens in the 

 British Museum. 



The wings of Ecuador birds average 58"9 mm. as compared 

 with 55"5 in Mexican birds. As regards the ashy grey 

 of the throat-patch, I cannot distinguish any noticeable 

 difference. 



Some specimens of C. m. intermedia come very close to 

 topotypical examples of C. m. columbiana, but, generally 

 speaking, Ecuadorian specimens are darker and richer both 

 above and below, and the yellow of the rump-patch is 

 distinctly brighter. 



It may be added that C, intermedia was originally described 

 by Salvadori and Festa as intermediate between C. colum- 

 biana Cab. and C. magniroatris Tacz, 



Goodfellow C' Ornithological Journey through Colombia 

 and Ecuador," Ibis, 1901, p. 319) states that "birds from 

 Western and Eastern Ecuador do not vary.^' In July he 

 found a nest with two eggs at Intaj.
