Tbis specimen agrees in every respect with a good series of K. o/nnirostris 

 from Paragua.y and Sontii Brazil. It is a perfectly adnlt male iu black jilumage, 

 with the inner webs of the remiges narrowly margined with white. The allied 

 K. aterrimus Kaup. differs at a glance by having the whole basal half of the inner 

 webs pure white as far as the shaft. K. unicolor Kaup sinks, therefore, as a 

 synonym of K. o/anirostris. The A', unicolor auct. (nee Kaup) from the upper 

 Amazons, however, is a very different bird, without any white at all on the ciuills, and 

 is much nearer A', orenocensis Berl. The synonymy of these species is as follows :

<? ad. Nearest to K. oreiwcemis Berl. and without any white on the quill- 

 lining, but easily distingnishable by the consiiierably darker sooty-black colour of 

 the upper parts and much darker, brownish black lower surface. In A', orenocensis 

 only the top of the head is dull blackisli olive, the back olivaceous-grey, and the 

 lower parts are likewise paler, slaty-olivaceous.

16. Muscicapa cristata Less. = Knipolegus cyanirostris (Vieill. j ? ! 



Muscicapa cristula Lessou, Tniile d'Orn. (1831) p. 385 [without locality ; descr. mala]. 

 Muscicapa crislata Puclieran, Arch. Mus. Paris, vii. (1855) p. 371 (crit.) 



One specimen, mounted, without label, but with the following notes on the 

 stand : " Bresil, Mr. de St. Hilaire, aout 1822. Muscicapa cristata Less, type." — 

 Al. 73 ; caud. 70^ mm. 



M. Pncheran {I. c.) already stated that this bird was a female of some .species 

 of Knipolequs. I was enabled to compare it with the females of the four sj)ecies 

 which came into the (pie.stion, and found it perfectly agreeing with that of 

 K. cyanirostris. It differs from a female from Rio Grande do Sul (Mus. H. v. B.) 

 only in having the lower parts less densely striated with blackish. 



17. Muscisaxicola striaticeps Lafr. & D'Orb. should be Knipolegus striaticeps 



(Lafr. k D'Orb.). 



There is iu the Paris Museum a mounted specimen, labelled as follows : 

 ^' Geositta striaticeps (d'Orb. et Lafr.). D'Orbigny. — -Bolivie " ; and its 

 stand bears the following inscription : " Bolivie, ( 'hiipiitos. D'Orbigny 1834.
