brown, edged with the same colour as the back ; bastard-wing, 

 primary-coverts, and quills dusky brown, edged with dull rufous- 

 brown, the inner secondaries more broadly washed with the latter 

 colour ; tail-featbers dark brown, washed externally with reddish 

 brown ; sides of face and under surface of body deep ferruginous 

 brown, the under wing-coverts and axillaries like the breast. Total 

 length 6-5 inches, culmen OS, wing 3, tail 2*5, tarsus 0-9. 



Young males at first resemble the old female, and gain the blue 

 plumage by a moult. 



This species shows a tendency to merge into G. concreta.

Adult male. Blackish with an indigo shade, with scarcely any 

 indication of bright blue on the forehead, cheeks, or wing-coverts. 

 Total length 6 inches, culmen 0-85, wing 32, tail 2-7, tarsus 0-9. 



Adult female. Similar to the same sex of G. cyanoides, but rather 

 more rufous, especially below. Total length 6-3 inches, culmen 0*8, 

 wing 3*05, tail 2*7, tarsus - 85. 



Mexican specimens are much the darkest, and Guatemalan in- 

 termediate between those from Mexico and Veragua. As Messrs. 

 Salvin and Godman remark, specimens from Panama, Colombia, 

 and Ecuador show much more blue on the forehead and cheeks ; 

 but I feel, in common with those gentlemen, that a perfect series 

 of intermediate links is likely to be found to connect G. concreta 

 and G. cyanoides (cf. Salvin and Godman, Biol. Centr.-Amer., Aves, 

 i. p. 346).
