[An adult male from Chietla, State of Puebla [tierra caUente), De- 

 cember, 1884, differs from an adult male from Mazatlan, another from 

 the Tres Marias, and a third from Boquillo, Nuevo Leon, in the follow- 

 ing characters: The entire fore part of the head, including the crown 

 back to behind the eyes, the postocular and auricular regions, malar 

 region, chin, throat, and jugulum, are dull slaty black, with a decided 

 glaucous or chalky cast; the metallic bronze collar across lower part 

 of jugulum is less than half as broad as the distance from its upper 

 edge to the mental apex ; the white breast-collar is very narrow, being 

 in its widest part only about .35 of an inch wide, whereas in northern 

 and western examples it is .50 or more in breadth; the mottling of the 

 wiugs is appreciably more delicate, and the color of the upper surface 

 of the four middle rectrices is a very rich purplish copper, instead of 

 bronzy copper-color. The measurements are: Wing, 5.30; tail, G.80; 

 culmen, .80 ; width of bill at rictus, .72. 



It is altogether probable that the birds of this species from Northern 

 and Western Mexico, and those from Puebla and other more southern 

 States of the Kepublic, represent two well-defined geographical races; 

 but in the great uncertainty which at present necessarily exists as to 

 which form represents the T. ambiguus of Gould, and likewise as to
