NOVITATES ZOOLOGICAE XXiX. 1922. 40& 



1167. Eriocnemis mosauera bogotensis Hart. = Eriocnemis mosquera 



bogotensis. 



Eriocnemis mosqiiera bogotensis Hartert, Nov. Zool. iv. p. 531 (1897 — Colombia). 

 Type : ^ ad., from a Bogota collection, bought in London. 



1168. Eriocnemis deibyi longirostris Hart. = Eriocnemis derhyi longirostris. 



Eriocnemis derhyi longirostris Hartert, Nov. Zool. ii. p. 69 (1895 — Bogota collections). 



Type : ^ ad., found in a Bogota collection. (Cf. Simon, Hist. Nat. des 

 Trochilidae, p. 371, 1921.) 



f 1169. Spathura underwoodi bricenoi Hart. = Ocreatus underwoodi discifer. 



Steganurus discifer Heine, Journ.f. Orn. 1863, p. 210 (Merida, Venezuela, ex Mus. Hein. iii. p. 66). 

 Spathura underwoodi hricenoi Hartert, Nov. Zool. vi. p. 72 (1899 — Merida, Venezuela). 



Type: ? ad., Andes of Merida, 2,500 m., 12. i. 1897. Salomon Briceno 

 Gabaldon & Sons leg. 



The Merida form is well separable from the Colombian one, but when 

 describing it I had overlooked Heine's earher name discifer. 



t 1170. Heliangelus dubius Hart. = Heliangeius clarissae aberr. 

 Hdiangelus dubius Hartert, Nov. Zool. iv. p. 632 (1897 — found in a Bogota collection). 



Type : (?, Bogota collection, bought in London. 



I have little doubt now that Simon correctly places my name dubius in 

 the Hst of synonyms of H. clarissae, but the throat is dark ghttering violet-blue, 

 not rosy-red with a pxirplish tinge. Therefore H. dubius can hardly be called 

 a melanism of clarissae ; the different shape of the ghttering throat patch is, I 

 am now convinced, due to incomplete moult. 



f 1171. Heliangelus simoni Boucard = Heliangelus barrali aberr. 

 Heliangelus simoni Boucard, Humming Bird, ii. p. 76 (1892 — Colombia). 



Cotype : c? ^-d., found in a Bogota collection by Boucard. Bought from 

 Boucard. Marked in Boucard's handwriting : " Heliotrypha simoni n.sp. typical 

 specimen. H. Bird, ii. p. 76. Colombia." A similarly marked cotype was sold 

 to the Field Museum of Natural History in Chicago, cf. Cory, Cat. B. Americas, 

 ii. 1, p. 266. 



I have no doubt that H. speciosa Salv. (of which simoni is absolutely a 

 fijmonym) is nothing but an aberration of H. barrali, from which it only differs 

 in having the throat-patch green instead of ghttering silvery leaden or greenish 

 lead-grey, especially since two of our specimens are quite intermediate ! 



(In Chapman's wonderful work on the Distrib. Bird-life Colombia no 

 mention is made of these birds, because his collections did not contain them. 

 As, however, exact locahties of H. barrali were known, and thus Mr. Chapman 

 left out over 60 remarkable Humming Birds known to have come from Colombia, 

 his Ust gives an insufficient impression of the richness of the Colombian avifaima).
