Calotliorax schreibersi, Gray, Hand-l. B. i. p. 136. 



Adult male. Upper surface dark shiuing grass-greeu ; a glittering 

 green frontal spot; under surface black; a glittering violet-purple 

 gular spot ; breast glittering green : flanks washed with green : 

 under tail-coverts and tail dark steel-blue ; central rectrices tipped 

 with green ; edge of the wing and edge of the outermost primary 

 chestnut ; bill black. Total length about 5"5 inches, wing 2'9 ; 

 tail, central rectrices 1*25, lateral 2-15 ; bill 1"2. 



Female (as determined by Hauxwell). Very similar to the male, 

 but with a fulvous rictal stripe. 



Toun^l birds have more or less fulvous or buff upon the sides of 

 the head stretching from the gape and extending under the eye; the 

 gular spot appears at an early age, but the frontal spot is the last 

 adult feature to be developed. 



A specimen from Sarayacu, which I should have thought to be a 

 normal female, has the gular spot, but the breast is much less 

 lustrous and the abdomen much greener ; moreover, the central 

 rectrices are green throughout.

Adtdt male. Similar to that of /. schreibersi, but with the whole 

 breast up to the gular spot black ; frontal spot hardly visible. 



Female. Like the male, but with a buff rictal stripe and the black 

 of the under surface tinged with green. 



The sexes of this species as determined by Whitely confirm the 

 observation of Hauxwell as to those of /. schreibersi.
