562 NOTES ON NEOTROPICAL BIRDS. 



siiinc as. the bird which we used to call U. cyanocephala. In his descrip- 

 tion of Trochilus quadricolor, Vieillot says. " mi beau vert brillc sur les 

 flancs," which is by no means the case in U. quadricolor of Elliot, but 

 applies well to U. cyanocephala auct. Therefore it becomes necessary 

 to bestow a new name upon the species named If. quadricolor by Mr: 

 Elliot, and I propose to call it in future U. ellioti Berl. I believe 

 the locality, Mazatlan, has not been mentioned elsewhere for this 

 species. 



15. Uranoniitra quadricolor (Vif.ill.) juv. fere pull, ex Orizaba = Sphenoproctuak 

 i_ eurvipennis (Liciit.) 



No. 38224 (juv. fere pull.) Orizaba (Botteri). 



This is by no means an Uranomitra, but a very young bird of Spheno- 

 proctus curvipennis, which is evident from the long yellowish legs audi 

 claws, as well as from the structure of the wings and the blackish tail— 

 f eat hers, also the grass green color of the back, etc. 



16. TJranomitra viridifrons Elliot ; correct. 



No.57774, male, Tehuantepec, Sta. Eugenia, 22d, December, 1868 (Prof. F. Sumi- 

 chrast). 



This species, which agrees with U. violiceps in the coppery hue 

 on the tail-feathers, I had never seen before. The locality, Tehuan- 

 tepec, is interesting as showing that U. viridifrons occurs in a locality 

 where U. violiceps is also found. I confess I am not quite convinced 

 that these forms are really distinct specifically. 



17. Uranoniitra guatemalensis Gould ex Ties Marias; name correct, locality erro- 



neous. 



No. 25855, female, Ties Marias, July. 1861 (Xantus). 



Agrees with specimens from Guatemala. The locality, Tres Marias, 

 is doubtless erroneous. See remarks under the head of Florisuga mel- 

 livora, etc. 



18. Agyrtria tephrocephala (Vieill.) ex Surinam = .l. viridissima (Less.). 

 No. 70577, Surinam (('. F. Hering). 



This is by no means=.A. tephrocephala (Vieill.), which is a much 

 larger bird with uniform pure white under tail coverts, and is exclusively 

 found in Southern Brazil. The Surinam bird belongs to the species 

 sometimes called A. linncei, or more recently by Mr. D. G.Elliott A. 

 till. act (Gml.). 1, however, believe it entitled to the name of A. viridis- 

 sima (Less.), the Trochilus tobaci of'Gmelin being most probably the 

 same as Pyrrhophwna erythronota. 



19. Arnazilia cyanura <iui i.t> c Retaleuleu, Guatemala; correct. 



No. 33654, Guatemala, Retaleuleu, Pacific coast, September, 1862 (O. Salvin). 



This is an excellent species which 1 had not seen before, it being some- 



' what rare in collections. If comes nearest to A. devillei ,sivc mariod 



( BoURC.),bu1 is easily distinguishable by its steel-blue tail, bluish instead 



of rufous under tail coverts, and the greater restriction of the cinnamon 



color on the base of the secondaries. The green of the bod}' above and
