This species, which may be always recognized by its bright orange 

 bill, seems rather variable in some respects. There is a fine series 

 of specimens of it in the Paris Museum, coUected by d'Orbigny and 

 Castelnau and Deville. In what seem to be tbe fully adults, the 

 front sides of the head, throat and breast, are all deep black, a 

 post-superciliary stripe and middle of the throat only being white. 

 Others, which I suppose are immature, have the white space on the 

 throat much larger, the black guttural band being confined to a 

 mere ring, which in some specimens is hardly apparent. 



15. Saltator albicollis. 



Saltator albicollis, Vieill. N. D. d'H. N. xiv. 107, et Enc. Me'th. 

 p. 793 ; Gray, Gen. p. 363 ; Bp. Consp. p. 489. 



Fusco-olivaceus ; subtus albo-subvirescens fusco maculatus : super- 

 ciliis gulague albidis. (Bp.) 



I have examined the type-specimen at Paris upon which Vieillot 

 founded this species, and from which Prince Bonaparte took the 

 short characters above given. It seems to be an immature bird, and 

 T think the locality, Cayenne, is most likely wrong. I suspect it was 

 probably from Trinidad, in which island there is a Saltator belonging 

 to this section with the flammulated under-plumage. Of this I 

 possess an example which may be described as follows : — 



" Above greenish-olive ; head darker, uropygium more cinereous ; 

 small yellowish supefcilia before the eye ; wings bordered with bright 

 olive-green ; tail brown likę the wing-feathers inside, rectrices edged 

 basally with cinereous ; under-surface white, regularly flammulated 

 with olive-green, middle of the throat and belly nearly all white, 

 just the shafts of the feathers only being olive ; under wing-coverts 

 white; bill black, with the apex yellow. Whole length 7*5 ; wing 3'5, 

 tail 3-3." 



There is a peculiar twist in the commissure in this bird which 

 seems to agree with what Vieillot says of his S. albicollis ; and I 

 think it very probable that it is this Trinidad species that ought to 

 bear that name. 



But until an accurate comparison can be made between a series of 

 individuals of each of the five members of this section of the genus, 

 I think it almost hopeless to determine the species satisfactorily.
