I cannot perceive any differences between the Teffe specimens and some others 

 from Paraguay and Peruambuco. 



In my revision of Spix's types (p. 612) I rejected the name C. solitarius as 

 uncertain, because in Vieillot's description no mention is made of the whitish colour 

 of the bill. I fiud now, however, that in young birds the bill is almost entirely 

 blackish, the extreme tip alone being dull whitish. There is, therefore, no reason 

 for not accepting Vieillot's term. 



21. Lampropsar tanagrinus tanagrinus (Spix). 



Icterus tanagrinus Spix, Av. Bra*, i. p. 67. tab. lxiv. fig. 1 (1824. — " in locis sylvaticis Parae").

Compared with four specimens from Mumlnapo, Upper Orinoco, and 1 c? ad. 

 from Guauoc.o, Orinoco delta (L. t. guianensis Cab.), this bird is much duller and 

 less glossy everywhere. I alluded to this difference in my revision of Spix's types, 

 p. 016; there is, however, a regrettable pen-slip, for it should read: " Sechs 6 <$ 

 von Munduapo . . . und zwei 8 6, Guanoko . . . unterscheiden sich durch viel 

 lebhafteren und mehr sta/Wblauen (not ' griiublauen ') Glanz," etc.

 tail 29 ; bill 13 mm. 



Differs from the types only by its slightly longer wings. 



A very near ally is T. pictum tSalv., of which the Triug Museum has lately 

 received a series from near Paramaribo. It is easily distinguishable from 

 '/'. guttatum by its duller green back, by having the throat, cheeks, and lower 

 ear-coverts white (not bright yellow), aud by lacking the yellow superciliary stripe. 



23. Todirostrum maculatum siguatum Bel. & Salv. 



Vide ■'•qua, p. 1 1. 



No. S89. 6 ad., 23. vi. 06. " Iris pale yellow, feet dark grey, bill black." 

 Agrees with specimens from Nauta, the top of the head being plumbeous with 



minute black centres to the feathers. As in one of the Peruvian skins before me, 



there are a few white dots in the middle of the forehead.
