( cS, jun. Guiana.) Both have the six middle tail-feathers of a dark metallic green, with scarcely any tinge of bluish; the rump and upper tail-coverts darker metallic green, with bluish reflexions. A young male from Demerara has the tail-feathers black, only the two innermost with green reflections on the outer web ; the outer tail-feathers are barred white and black at the apical half, like those of the female. W e possess an old male from Cayenne, which shows a very peculiar difference (as far as I know, not yet mentioned by any describer), viz. in having the tail-feathers, instead of green in every light, with a dark indigo-blue lustre, and the greater part of tbe uropygium and upper tail-coverts vivid dark purplish blue. If new, T. cyanurus, Hartl.; otherwise it agrees in every respect. 19. TROGON COLLARIS, Vieill.; Scl. Cat. p. 276; Leot. p. 103 (descr. opt.) ; Taylor, I. c. p. 88. Trogon curucui (L.); Cab. et Heine, Mus. Hein. iv. p. 176. One specimen, not different from a specimen from Surinam in the Bremen collection. T. curucui, Linne, based upon the description of Marcgrave and Brisson, is most probably this species, but cannot be made out with certainty. The white and black bars on the three outer tail-feathers, as described by Brisson, are very well referable to this species; but he does not mention the white cross band which separates the golden green of the jugulum and the scarlet of the breast. The figure of Trogon curucui by Hahn (Vog. aus As. Afr. A m . &c. Liefer, vii. t. 3) belongs undoubtedly to this species, and not to T. melanurus, Sw., as concluded by Dr. Cabanis (Mus. Hein. iv. p. 201). 7'"' (Trinidad.) - (Surinam.) -• (ap. Leot.) A very good description of this species is given by Dr. Leotaud. [jong. al. 4" 3'" 4 5 4 5 caud. 4" 10'" 4 8h 4 6~ rostr.
