758 ON THE BIRDS OF EASTERN PERU. [JunC 27, 



(100.) lODOPLEURA ISABELLA, Parz. 



Both sexes and the young of this fine species are in the collection. 

 The female is distinguished hy the want of the violet side-tufts (as 

 in /. pij)7-a). 



(106.) Chloropipo, sp. — ? 



A female, probably referable to a species of this genus. Sclater's 

 collection contains a similar skin from Ecuador. 



-f' (128.) Ch^tura brachycerca, sp. nov. (PI. XXXIV.) 



JEneo-niffra : dorso inferiore uropygio et eauda tola cum tectrici- 



bus c(tud<ii svperioribus et inferioribus fuscescenti-cinei'eis ; rec- 



tricum rachidibus acuminatis nig?'is : cauda brevissima : rostro 



et pedibus nigris : long, tota 4*0, ala: 4"6, caudce 1'2, tarsi 0*4. 



Hab. Peruv. orient. Xeberos {Bortlett). 



This is a new and very distinct species of the small group of Ameri- 

 can ChcetiircE, remarkable for its short tail. Mr. Bartlett's collection 

 contains nine specimens of it, all from Xeberos. The sexes are alike. 



(145.) POLYTMTJS LETICORRHOUS, Gould. 



See our remarks on this species {anteH, p. 584). Many speci- 

 mens of it are in the present collection. 



j" (153.) PiAYA MEHLERi, Bp. ; Schlegel, Mus. d. P.-B. Cuculi, 

 p. 57. 



Piaya nigricrissa, Sclater. 



It appears from Schlegel' s recent researches that Sclater was 

 mistaken in considering Bonaparte's type of P. mehleri referable to 

 the Mexican form of this species (c/. P. Z. S. 1860, p. 285), and 

 that the specimen in question was from Bogota. It follows, there- 

 fore, that this bird must be called Piaya mehleri. 



^(154.) Piaya melanogastra (Vieill.). 



Cuculus melanogaster, Vieill. N. D. viii. p. 236, et Enc. Meth. 

 p. 1337. 



Cuculus cayanus, var., Gm. S. N. i. p. 417. 



Macropus caixana, Spix, Av. Bras. i. p. 54, t. 43. 



Piaya brachyptera. Less. Trait, p. 140 ; Bp. Consp. i. p. 11 1. - 



P. melanogastra, Schlegel, Mus. d. P.-B. Cuculi, p. 59. 



Pyrrhococcyx brachypterus, Cab. in Schomb. Guian. iii. p. 714. 



Several examples of this bird from Chyavetas. Mr. Eyton's col- 

 lection contains a skin of the same species from Guia {Wallace).

Celeus citreopygius, Bp. MS.
