140 Mr. D. G. Elliot on D’ Orbigny’s Specimens of 
Thaumatias neglectus. 
Ornismya bicolor, D ; Orb. & Lafr. Syn. Av. ii. p. 30, sp. 21. 
Hab. Yungas and Moxos, Bolivia. 
Male. Top of head, nape, and mantle metallic green ; throat 
and upper part of breast brilliant metallic blue, the white base 
of the feathers on the throat and breast showing conspicuously 
amid the blue; but this may be caused by the plumage of the 
specimen being disarranged. Back, rump, and upper tail- 
coverts light greenish bronze. Wings purplish. Blanks and 
lower part of breast shining green. Abdomen whitish. Under 
tail-coverts pale brown, margined with white. Tail pale 
greenish bronze; a subterminal black bar, as in many species 
of Thaumatias , is present upon all the feathers excepting 
the two median ones. Bill very slender and pointed. Maxilla 
black; mandible flesh-colour. Feet black. Total length 
3J inches, wing 2, tail 1^, bill |. 
Female. Head and upper parts, sides of throat, and flanks 
shining grass-green. Centre of throat and underparts whitish, 
apparently spotted with metallic light green. Tail like that 
of the male, tips of lateral feathers whitish. Under tail- 
coverts whitish. Wing purple. Maxilla broken off, the base 
black; mandible flesh-colour. Feet black. Length 3 J inches, 
wing 2, tail 1J, bill f. 
This specimen is in a very poor state, and the colour of 
some parts is difficult to make out correctly. Some of the 
tail-feathers are wanting; those that remain resemble the 
rectrices of the male. 
Thaumatias neglectus cannot be confounded with other 
species of the genus, as it does not resemble any of them. 
Chrysuronia chrysura. 
Ornismya chrysura, Less, Qis.-Mouches, Suppl. p. 107, pi. 4. 
Ornismya ruficollis , D’Orb. & Lafr. Syn. Av. ii. p. 30, sp. 22. 
Hab. Santa Cruz, San Juan de Chiquitos, Yungas. 
I place O. ruficollis, D’Orb., as a synonym of C. chrysura , 
from the fact that I find a specimen brought from San Juan 
by D'Orbigny in the gallery of the Paris Museum, which 
answers very well to his description. It is the only species 
to which I can refer 0 . ruficollis.
