It is a rare species. My specimens were collected by 

 Gaumer, in Yucatan. 



I have also one specimen sent by the same collector, at the 

 same time, which 1 consider as the female of that species. 

 It is exactly coloured as the male, but all the underside is 

 cinnamon as A. cinnamomea ; the tail is exactly like that of 

 the male w^ith greenish bronze spots at tips of outermost 

 rectrices ; the external webs of these rectrices are also bronzy- 

 green.

Habitat. — Mexico.

 rufous margined, and tipped bronze, lateral rufous with ex- 

 ternal webs and tips bronze. Underside metallic green, 

 golden on breast and sides of neck. Abdomen pale rufous. 

 Flanks pale rufous, washed with golden feathers. Undertail- 

 coverts pale rufous. Wings purplish brown. Bill flesh colour

This species was discovered by Mr. Salle and myself, at 

 Tospam, near Cordoba, Mexico. It is closely allied to 

 A. yucatanensis, but easily distinguished from that species 

 by the colour of the abdomen, undertail-coverts, and flanks, 

 and the tail. In A. yucatanensis, the lateral rectrices are 

 much narrower, with small bronzy-black tips, instead of large 

 bronze tips.
