NOVITATES ZOOLOGIOAE XXI. 1014. 1~5 



No. 1 is an immature male, with the bnflt' wing-banrls incompletely developed, 

 thongh otherwise in pert'eet plumage. Compared with three fine SS ad. from 

 Quito in the Muiiieh Mnsenm, it has the back slightly darker green, and the breast 

 as well as the abdomen much duller, dingy greenish yellow (instead of bright 

 sulphur yellow). This, however, is due to some external influence, since a few of 

 the abdominal feathers that have escaped this artificial alteration show exactly the 

 same shade of yellow as our Quito examples. E. ferruffineiceps thus becomes a 

 synonym of M. p. pulcher, whose range appears to be restricted to Ecuador.* 



The Colombian form, M. pulcher id //is Sol., differs by its darker, brownish 

 olive back, ochraceous (instead of butf) wing-bands, deep orange-brownish chest, 

 and larger size (wings 55-00, as against 50-54 in M. p. pulcher). There is no 

 difference in the extent or colour of the cinnamon vertical jiatch.

This specimen, an adult bird in good plumage, agrees in every particular with 

 several others from Valparaiso. Dr. Allen, when describing L. fuscescens, said 

 that the type had been obtained on the " Falls of the Rio Madeira," Eastern 

 Bolivia, by the botanist H. H. Rusby. On the original label, however, the words 

 " Falls of the Rio Madeira" are scratched out and replaced by the indication 

 •' Valparaiso, June 1885. Rusby." The latter locality is, no doubt, correct, and 

 there can be no question that L. fuscescens is merely a synonym of L. aegithaloides, 

 the type of which came likewise from Valparaiso. 



Birds from Southern Chile (Valdivia) are somewhat different, having the back 

 more rufesceut (less earthy) brown, the abdomen decidedly washed with buffy, the 

 white throat bordered below by a number of dusky spots, while the rufons portion 

 at the base of the outer web of the primaries is less extended and of a paler hue. 

 Moreover, the outer margin to the e.xternal rectrices is pure white and more 

 abruptly defined. 



The wing is slightly (55 to 56 mm.), the tail conspicuonsly (85 to 87 mm.), 

 shorter. The inhabitants of Southern Chili very likely represent a distinguishable 

 race, but I should like to see more specimens before giving it a name,
