haviu"' the whitish superciliary streak continaed to the posterior end of the ear 

 coverts. This character alone wonld be sufficieut to jirove that the bird lias nothing 

 to do with S. striatipictus (= albicollls anct.), in wliich species the snperciliavies 

 always end above the eye. Moreover, the lower mandible is pale yellowish, 

 except for the blackish basal half of the sides, just as in a series of 16 specimens of 

 S. ynadeloupensis, while in 71 examples of S. striatipictus (= albicollis anct.) 

 the whole lower mandible is deep black, only in a few skins a very small 

 spot at the extreme tip being yellow. In Vieillot's type specimen, also the 

 whole apical half of the upper mandible is yellow, as in some examples from 

 Gnadelonpe, Santa Lncia, etc. Most of the specimens of S. striutipictiis have the 

 whole ujiper mandible deep black; sometimes there is a minute yellow spot at the 

 very tip to be seen, but never more I 



After all, there can be no doubt that Vieillot's type is a sjiecimen of S. guade- 

 loupensis with wrong locality. Comjiared with some examples from Gnadelonpe 

 and Santa Lucia, it presents but very slight diflerences. The back appears rather 

 greyer, since the olive-green apical portion of the feathers is mostly worn off, but 

 on the head the green colour is well to be seen. The same applies to the under- 

 parts, which are rather greyer, less greenish, with the middle of the abdomen and 

 the under tail-coverts paler bnfty than usual. 



The nomenclature of the two species which enter into the question is as 

 follows : 



Saltator albicollis Vieill. 



Stillator albicollis Vieillot, Nouv. Did. xiv. (1817) p. 107 [■' Cayenne "— errore !].

 S.E. Brazil, vicinity of Jiio], 



1. Mus. Brit, ex coll. P. L. Sclater (<?) ad. "Sonth America.— Argent" Type 

 of P. lactea Sharpe. [The specimen is of the well-known "/^/o-makc."]— Wing 47 ;

2. Mus. Brit, tj ad. Rio de Janeiro. Alex. Fry coll. No. 263.— Wing 45J ; 

 tail 44; bill lOJ mm. 



This is a very distinct species, and easily distinguishable from P. bilineata 

 (Bp.), with which I united it in the Tierreich, 18. Lief. p. 27, owing to lack of 

 material. 



P. lactea agrees with P. bilineata in having the lores, cheeks, ear-coverts 

 and broad snperciliaries pure white, but differs at a glance by its much darker, 

 slaty-blue (instead of bluish grey) ujiper surface, entirely white outer tail-feather 

 without any black at the base, and beautiful creamy colour of the breast and
