Discovered by Salle near Cordova, in Mexico, this species veas first described by 

 Mr. Sclater in 1856 ^, and since then its range has been traced throughout Central 

 America to the State of Panama *. In Costa Rica and the adjoining portion of the 

 State of Panama it is found associated with its near ally A. pallidigularis, some speci- 

 mens from this region being somewhat intermediate in character between the two 

 birds. As a rule A, cervinigularis may be distinguished by its darker head as contrasted 

 with the back, the deeper fawn-colour of the under surface, and rather more definite 

 edges to the feathers of the breast, more definite superciliaries, &c. In size there is no 

 appreciable difference between the two. 



In Guatemala, A cervinigularis is restricted in its range to the forest-region of Vera 

 Paz, which spreads northwards of Coban to Mexican territory. It has not been 

 noticed in any of the forest country bordering the Pacific Ocean. Of its nesting-habits 

 nothing has been recorded.
