places in the Western Ancles between 5000 and 7000 feet, 

 though we procured only females at the lower altitude in 

 August. I noticed the same facts with regard to other 

 members of this genus^ namely that we collected only males 

 in one locality and females in another, and always at slightly 

 different altitudes. The females of C. rufigularis are less 

 marked with black on the breast than the males, while the 

 markings are smaller and more confined to the upper breast, 

 and are not continued so far down the sides. In two skins 

 the throat is also of a lighter rufous. 



71. Callistb aurulenta (Lafr.). 



Nine males and three females from Santo Domingo 

 and Intaj, W. Ecuador, between 600 and 1500 feet. They 

 suddenly made their appearance after we had been at Intaj 

 a few days, but all that we shot there in July were males, 

 and the females were procured at Santo Domingo only. 

 The latter appear to differ somewhat from the former in 

 having the golden yellow of the rump and breast of a 

 huffish hue, and the feathers of the back and wing-coverts 

 edged with greenish yellow. 



72. Calliste icterocephala (Bp.). 



A large series from Santo Domingo, Gualea, and Intaj. 

 They were generally to be found in the banana-plantations. 

 The females are distinguishable by their greener heads, 

 darker throats, and greener rump and underparts. Like 

 all the other members of this genus, these are restless birds, 

 always on the move and constantly uttering their sharp little 

 call-notes. 



73. Calliste vitriolina (Cab.). 



Our skins are from Gualea, Nono, and Intaj, W. Ecuador, 

 and (two) from the Chota Valley, North Ecuador. The latter 

 appear to be bluer on the back, wings, and tail. These birds 

 were also numerous along the hedgerows around Popayd,n, 

 South Colombia, and we obtained a good series of skins there, 

 which were among those that we lost. 



74. Calliste gyroloides (Lafr. & D'Orb.). 



Nine adult males, one young male, and two females from
