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



(100.) lODOPLEURA ISABF.LL^, PsrZ. 



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

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

 in I. pipra) . 



(106.) Chloropipo, sp. — ? 



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

 collection contains a similar skin from Ecuador. 



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



^neo-nigra : dorso inferiore uropygio et cauda tota cum tectrici- 

 hus caudm superiorihus et inferioribus fuscescenti-cinereis ; rec- 

 tricum rachidibus acuminatis nigris : cauda brevissima : rostro 

 et pedibus nigris : long, tota 4*0, alee 4-6, caudce 1-2, tarsi 0*4. 

 Hab. Peruv. orient. Xeberos (Bartlett). 



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

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

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



(145.) POLYTMUS LEUCORRHOUS, Gould. 



See our remarks on this species (anteil, p. 584). Many speci- 

 mens of it are in the present collection. 



(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 {cf. 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. Me'th. 

 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. 



Prjrrhococcyx 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^ . 



(169.) Celetjs citreopygitjs, sp. nov. 



Celeus citreopyyius, Bp. MS. 



Celeo-picus jumana, Malh. Mon. Pic. ii. p. 27 (partim). 



(S . Luride badius : secundariis et interscapulio cum ventre imo 

 et crisso castaneis : dorso postico aurantiaco : primariis extus 

 et cauda nigricantibus : subalaribus citrinoflavis hand fascia-
