Two males and one female from Humaytha have the sides of the neck dull 

 greyish or olive-brown, like specimens from Teffe, Yijnitos and Sarayacn, Peru, 

 and agree well with the original description of M. analis. In No. 1006 there is 

 just a faint vinaceous tinge to be seen on the posterior portion of the ear-coverts, 

 while Nos. 968 and 941, as well as the female from Borba, have the sides of the 

 neck decidedly pale vinaceous-cinnamon (Ridgw. iv. 15). The same variation is 

 to be observed in two specimens from Pani : one in the Paris Museum, obtained by 

 Mons. Baraquin, has the sides of the neck greyish brown, like several skins in 

 the Humaytha series ; the other in the British Museum, collected by Dr. Wallace, 

 has them clear vinaceous-cinnamon, like the Borba bird ! 



The examples from Humaytha, Teffe, etc., are bistre brown, those from Burba 

 and Para rather darker and more rufescenf brown on the upper parts. 



Skins from British Guiana and Cayenne, F. a. crissa/is (Cab.), however, differ 

 very conspicuously from all the Brazilian ones by having the sides of the neck
