EE3IAEKS. — I^Tever Laving seen a specimen referable to this species, 

 I follow ]\fcssrs. Sclater and Salvin in recognizing- it as distinct from 

 T. melcuicJiolicus, withont knowing, however, their grounds for doing so. 

 In his remarks upon T. melanckoUciis, in the "Proceedings" of the Zo- 

 ological Society of London for 1870, p. 572, Dr. Fiusch alludes to T. 

 iilbujularis, as follows: 



" In contradiction to the views of Dr. Cabanis, I agree with von Pelzeln 

 in considering T. albigularis, Burm. (Bras, ii, p. 405), to be specifically 

 distinct fiom T. melanchoUcus. A spechnen from Brazil in the Bi-emen 

 3Iuseum shows the chin and throat decidedly white ; whereas these parts 

 in T. melanchoUcus are whitish gray. Four specimens from Xorthem 

 Brazil (Ceani) all show this latter character." 



Unfortunately, the other distinctive characters of Burmeister's species 

 are not alluded to. That mentioned by Dr. Finsch, i. e., the whiteness 

 of the throat, seems of little account, since, according to the specimens 

 which I have seen from that region, it is customary for T. mchtucJtoIicus 

 from northern South America to have the throat nearly, if not quite, 

 white. The only characters given in Burmeister's description which 

 appear really distinctive are the smaller size and the whitish green 

 instead of pale grayish edgings to the wing-feathers. It is, therefore, 

 solely upon the presumption that Messrs. Sclater and Salvin and Dr. 

 Finsch have good reason for considering the species distinct from me- 

 lanchoUcus that I so here consider it.

Keiniarks. — Although this supposed species is not recognized by 

 Messrs. Sclater and Salvin in their N'omencJator Avium N'eotrojyicaUum, 

 it would seem from the description above quoted, and the remarks which 

 follow (of which a literal translation is given), to be ^'ery distinct from 

 any other species of the genus. The black encirclement of the yolk- 

 yellow crown, the spotted back, and several other characters mentioned, 

 certainly cannot be reconciled in any other known species.
