 Petasophora serrirostris, G. R. Gray, List of Gen. of 

 Birds, 2nd edit. p. 17. 

 Hab. Brazil. 



Sp. 2. Petasophora cyanotus. 



Trochilus cyanotus, Bourc. Rev. Zool. 1843, p. 1 ; Ann. 

 de Lyons, torn. vi. p. 41, but not the cyanotus stated 

 by Lesson to be synonymous with DelphincB. 

 This species appears to be the representative in the Cordilleras of 

 the P. serrirostris of the Brazils, from which it is at once distin- 

 guished by the blue colouring of the ear- coverts. 

 Hab, Bogota. 



Sp. 3. Petasophora thalassina. 



Trochilus thalassinus. Swains. Syn. Birds of Mexico, in 

 Phil. Mag. June 1827, p. 441. 

 Differs from the other members of the genus by being of a smaller 

 size and by the greater extent of the blue on the cheeks and ear- 

 coverts ; it has dso a slight wash of blue on the chin and centre of 

 the abdomen. 

 Hab. Mexico. 



Sp. 4. Petasophora Anais. 



Ornismya Anais, Less. Col. Supp. pi. 3 ; Less. Troc. pis. 



55, 56, 57 ; Rev. Zool. 1838, p. 315, 1839, p. 19 ; 



Less. Velin, no. 1 1 ; Echo du Monde savante, 1843, 



no. 31. ined. pi. 11. 



Much confusion evidently exists with respect to this species, M. 



Lesson having figured one bird and described another with the same 



appellation ; under these circumstances it will be to the advantage 



of science to retain the specific term Anais for the bird best known 



to ornithologists by that designation, the species so common in all 



collections from Bogota, the great Anais of the French, and which is 



a very fine species, distinguished by the existence of a well-defined 



band of blue on the throat. The female is fully as bright as the 



male, but at least one-third smaller in size. 



Hab. Venezuela and all the Cordilleras in the neighbourhood of 

 Bogota. 



Sp. 5. Petasophora iolota, sp. nov. Pet. capite, et corpore su- 



periore saturate viridibus ; mento, spatio suboculari, auribus, et 



medio abdomine intense^ metallice, cyaneis ; corpore inferiore ni- 



tense viridi ; guld quasi tessellatd, quia media plumce quam pogonice 



extremcc obscurius nitent ; tectricibus caudce inferioribus pallidis 



ad margines pallidioribus . 



Head and all the upper surface deep green, in some specimens 



tinged with gold; primaries and secondaries brown, tinged with 



purple ; chin, space beneath the eye, ear-coverts and the centre of
