574 MESSRS. SCLATER AND SALVIN ON [May 23, 



Sclerurus bnmneus, Sclater, P. Z. S. 1857, p. 17, et 1858, p. 62. 



Capim River. 



One example, fully agreeing with Sclater's specimens from Bogota 

 and Cayenne, upon which he has founded his S. brunneus. On re- 

 vising the synonymy of this group, however, it appears that the 

 species indicated by Vieillot as Thamnophilus caudamitus was from 

 Guiana ; and it is, therefore, this Guianan species (and not the South- 

 east-Brazilian form) which ought to bear his name. The bird of the 

 Brazilian wood-region must therefore take the next earliest name 

 applicable to it, and stand as Sclerurus umbretta (Licht.).

 Am. Cat. p. 149. 



Capim River. 



A single specimen of Mr. Wallace's agrees in every respect with a 

 considerable series of skins of this species in our collections from 

 Mexico and Central America. They are from the following locali- 

 ties : — Mexico, Cordova (Salle), Jalapa {De Oca); Guatemala, Choc- 

 tum and Pacific slope (Salvin) ; Veragua (Arce). We have been 

 unable to refer to Swainson's iS". rufcollis, stated to be figured in bis 

 * Birds of Brazil.' In all copies of this work to which we have had 

 access, this plate (t. 79) and also t. 79t, where S. albigularis of the 

 same author is figured, are deficient. It is possible that this bird 

 may be the species figured in the first of these two plates, in which 

 case it should bear Swainson's name. 



60. Synallaxis rutilans (Temm.). 



An immature specimen, collected at Para in May 1849, of tbis 

 species. 



61. LePTOXYURA CINNAMOMEA (Gm.). 



Mexiana and Tocantins. 



62. Philydor erythrocercus, Pelzeln. 



Para, March and May 1849, three examples. 



One of these skins (marked c? ) agrees very nearly with Sclater's 

 Cayenne specimen of this species, and with a typical specimen of 

 Natterer's from Barra, also in his collection. Two others are larger 

 and stronger, clearer white below, and with a more rufous tinge on 

 the wings. The superciliary stripes are absent, and the tail is longer 

 and more rounded. We are in some doubt whether these latter spe- 

 cimens do not belong to a distinct species. 



^ 63. Glyphorhynchus cuneatus, Licht. 

 Para and Capim River. 



64. Dendrocincla fumigata (Licht.); Burm. Svst. Ueb. iii. 

 p. 8. 



Three specimens from Para, referable, as far as we can make out, 

 to this species.
