Discovered by Sallé near Cordova, in Mexico, this species was first described by 
Mr. Sclater in 18561, 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. Asarule 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.
