410 NOVITATES ZOOLOGIOAE XXIX. 1922. 



? f 1172. Heliangelus daudia Hart. = ? Heliangelus clarissae aberr. 



Hdiangdus clavdia Hartert, Nov. Zool, ii. p. 484 (1895 — " Colombia "). (See also Nov. Zool. 1897, 

 p. 532.) 



Type : c?, found in a Bogota collection by Monsieur Gounelle, of Paris. 



I am now inclined to think that H. clavdia (not " Claudiae " as quoted by 

 Simon) is a melanistic variety of H. clarissae ; the uniform black upperside and 

 tail, with faint purplish gloss, and the blackish, glossless abdomen, suggest 

 melanism, and the colour of the throat, which is dark violet-blue instead of 

 glittering rosy-red (as in clarissae) may also be due to melanism. It is, however, 

 peculiar, if Simon (p. 367 of his book) says of H. dubius that it is "Melanisme," 

 and of Claudia " peut-etre un premier degre de Melanisme (?)." Certainly the 

 other way round would be more correct. Of this melanistic form we have now 

 2 cJ and 1 apparent $, which is Uke the ^ on the upperside, while the throat is 

 duU black with whitish edges to the feathers. 



(I am convinced that H. violicollis, Salv., is an aberrant H. strophianus — ^in 

 fact this is sure to be the case, if my dubius is only clarissae.) 



1173. Metallura theresiae Simon = Metallura theresiae. 

 Metallura theresiae Simon, Nov. Zool. ix. p. 181 (1902 — ^Tayabamba, province of Pataz in Peru). 

 Cotype : ad., Tayabamha, 2,500 m., January 1901. G. A. Baer leg. 



1174. Metallura atiigularis Salv. = Metallura atrigularis. 



Metallura atrigularis Salvin, Bull. B.O. Club, i. p. xlix. (1893 — " Hills near Sigsig, not far from 

 Cuenoa, Ecuador, alt. 12,000 feet "). 



Type : ^ fere ad., hills near Sigsig, 12,000 feet. 0. T. Baron leg. 



1175. Metallura baroni Salv. = Metallura haroni. 

 Metallura harcmi Salvin, Bull. B.O. Club, i. p. xlix. (1893 — " Hills near Cuenoa, alt. 12,000 feet "). 

 Type : <? ad., Mts. near Cuenca, 12,000 feet. 0. T. Baron leg. 



1176. Metallura smaragdinicollis septentrionalis Hart. = Metallura 

 tyrianthina septentrionalis. 



Metallura smaragdmicoUia septentrionalis Hartert, Nov, Zool. vi. p. 73 (1899 — North Peru : Caja- 

 bamba, Cajamarca, Huamaohuco, Levanto, Celendin). 



Type : ^, Huamachuco, 10,400 feet, March 1894. 0. T. Baron leg. 



My M. 8. septentrionalis (not " meridionalis " as quoted by Simon, p. 381 !) 

 is in my opinion certainly different from the specimens collected in Peru by 

 Whitely in 1873, having longer wings and darker coloration. If Boucard and 

 Simon [I.e.) are right in separating the latter from Bolivian, examples, then there 

 seem to be three forms. 



There can be no doubt that Met. smaragdinicollis is a subspecies of M. 

 tyrianthina. 



1177, Chalcostigma purpureicauda Hart. = Metallura purpureicauda. 

 Chalcostigma purpureicauda Hartert, Bull. Brit. Om. Club, vii. p. 28 (1898— Colombia). 



Type : ^, found in a Bogota collection in London. 



I follow Monsieur Simon in placing this peculiar species, which seems to be 

 unique in the Tring Museum, in the genus Metallura, but if this is done I cannot 

 eee how Chalcostigma and Selatopogon Sim. can be separated from Metallura.
