mixed bronzy green and |iale cinnamon; abdomen whitish along the middle. Under 

 tail-coverts white, strongly washed with cinnamon, liut not " white with base rnfou.'*," 

 as described by Koncard. Wings pui-plish brownish black. Lateral pair of rectrices 

 purplish black, with a cinnamon spot on the tip of the inner web, and an indication 

 of a cinnamon edge on the latter. Next pair witli a distinct edging and a more or 

 less indistinct spot near the tip ; the following pairs with cinnamon edgings on both 

 webs ; central pair dark metallic green, with a broad edging of cinnamon on both 

 webs, except on the tip. Bill black, pale at utmost base of mandible. Wing, 43 mm. 



Adult Female (Faldas de Irazu, January, in full plumage). — Above like the 

 male. Three lateral pairs of rectrices with broad white tips. Below also like the 

 male, but the throat white, washed witli cinnamon and sjjeckled with round spots of a 

 dark brown, glossed with bronzy green. ]']ar-co\-erts dark brown, mandible more pale 

 than in the male. Wing, 42 mm. 



Some males, La Estrella, Cartago, .March and April, are strongly in moult and tlie 

 tliroat is darker. 



A female, Santa JIaria de Dota, September, very badly in moult, is less speckled 

 on the throat, has broader white tiiis to the outer rectrices and narrower edgings on 

 the central rectrices. It seems to be a young bird. 



2. Urosticte ruficrissa Lawr. 



Several specimens of this somewhat rare bird, which differ in no way from 

 P^cuador specimens, were found by Mr. Rothschild in a lot of the well-known Bogota 

 trade-skins. The species is not hitherto registered from Bogota collections, nor even 

 from Colomliia. (Cf. Berlepsch, " Uebersicht der Colibri-Arten in den sog. Bogota- 

 Oollectionen," in Jourii.f. Orn., 1887, and Boucard, " Comj)l. List up to date of the 

 Humming Birds found in Colombia," in Humming Bird, ii., 1892.) 



:>. Eriocnemis russata <iould. 



I am sorry to say that E. and CI. llartert, when recording Eriucnemis Uujeus on 

 J). 60 of NoviTATES ZooLOGlCAE, I. (1894), made a mistake, for the species collected 

 by Baron on the Rio Pastassa is really E. russata. It is, nevertheless, of much 

 interest to have found that the male has the '" tibial tufts " (cf. Salvin, Cat. B., x\i., 

 p. 381) partly white and partly pale chestnut, while the female has them quite 

 white, and that the wing of the feviale is 2 or 3 mm. shorter (see Novitates 

 ZoOLOGlCAE, I.e.). I am, however, of opinion that, in spite of our mistake, the 

 identity of E. Imjens and E. squainata, the former being the female, the latter the 

 male, will soon be proved, as it will only be a parallel case to E. russata. (See also 

 Houcard, Genera H. B., p. 251.) 



4. Eriocnemis derbyi longirostris subsp. nov. 



Eriocnemis derbiji has originally been described from the A'olcan de Purace in 

 Southern Colombia (Del. i<- I^ourc, Rev. ZooL, 184G, p. 30(!). Afterwards specimens 

 from the neighbourhood ol I'dpayan and Pasto in Southern Colombia (collected by
