140 Mr. D. (Jr. Elliot on D'Oj'biyay'a 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. Flanks 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 

 3 J inches, wing 2, tail \\, 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| inches, 

 wing 2, tail \\, bill |. 



This specimen is in a very poor state, and the coloiu* of 

 some parts is difiicult 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. Ois.-Mouches, Suppl. p. lOT, pi. 4. 



Ornismya ruficoUis, D'Orb. & Lafr. Syn. Av. ii. p. 30, sp. 22. 



Hab. Santa Cruz, San Juan de Chiquitos, Yungas. 



1 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 O. r/fficol/is.
