A specimen of C. prasina, Less.^ brought by D'Orbigny 

 from Ayupaya, as ascertained by the Museum Catalogue, 

 I believe to be the O. mellisuga of the ' Synopsis Avium,^ 

 for the following reasons : — The locality of Ayupaya is only 

 given twice among D'Orbigny's examples; and the present spe- 

 cimen is the only Humming-bird brought by him that I have 

 been able to find in the Museum as having come from that 

 place, excepting the Metallura smaragdinicollis, about which 

 there cannot be any difficulty. This would seem to point it 

 out as the one intended by him as 0. mellisuga. In the 

 Museum Catalogue it is called the Saphir-emeraude, no Latin 

 name having been employed. The next species of the 'Syn- 

 opsis ' he gives is 0. bicolor ; and he asks if that is not the 

 young of the Saphir-emeraude, " Junior avis ? le Saphir- 

 emeraude," as though he had in his mind the present 

 species, which he called in the Museum Catalogue by that 

 name. These two circumstances seem to show that we 

 shall not probably go wrong if we place D^Orbigny^s 0. mel- 

 lisuga as a synonym of Chlorostilbon prasina (Less.). Again 

 M. Beauperthuy has placed in the gallery a specimen of C. 

 prasina which bears on the ticket the name O. mellisuga. 

 This seems to me also an indication that D^Orbigny^s name 

 was intended for the same species. 



Two specimens of the bird called Ornismya bicolor by 

 D^Orbigny are in the Museum, numbered 349 and 385. One 

 of them, a male, is mounted, and has upon the stand Circe 

 doubledayi in the handwriting of Bourcier ; the other, a skin 

 of a female in very poor condition, is marked on the label 

 ' Yungas,^ in D'Orbigny's writing. They are rather small 

 delicately shaped birds, of a species apparently undescribed, 

 belonging to the genus Thaiimatias. Most certainly they 

 have nothing to do with Circe doubledayi. I propose to call 

 the species
