1867.] THE BIRDS OF EASTERN PERU. 1^7 



(72.) Myrmeciza hemimel.bna, Sclater, P. Z. S. 18.58, p. 249. 



A single skin, agreeing with the typical specimen in the British 

 Museum. 



(74.) Hypocnemis myiotherina (Spix). 



A series of ten specimens of this species proves, what we had long 

 suspected, that " H. melanosticta, Sclater, J" (as figured P. Z. S. 

 1854, pi. Lxxm.), is the young male of this bird before the black 

 throat is attained; and " H. melanosticta, $ ," the female of this 

 species. H. elegans, Sclater, of Bogota, is also probably merely the 

 female of the same bird rather more deeply coloured below. 



(80.) EusCARTHMUs spiciFER (Lafr.). 



See our remarks on this species, P. Z. S. 1866, p. 1S7. 



(82.) Leptopogon peruvianus, sp. nov. 



SitniUs L. amaurocephalo, ex Brasilia or. nierid., sed minor : 

 pileo saturatiore, et cauda brunnea unicolure : lony. lota 4"5, 

 alcB 2"3, caudce 2"0. 



Hab. Peruv. orient. Chyavetas (Bartlett). 



Dr. Cabanis has lately separated the northern form of this species 

 as L. pileatus (Journ. f. Orn. 1855, p. 414). This is a third local 

 form, resembling L. pileatus in the deep colour of the head, but 

 smaller than either of the others, and without any green edgings to 

 the tail-feathers. The bill of the single specimen sent is rather 

 stouter, and the chest somewhat darker. 



(92.) Empidochanes fuscatus (Max.). 



See our remarks on this bird {antea, p. 578). We should rather 

 have expected to find here the Cayenne form £. olivus. 



(95.) Tyrannus aurantio-atro-cristatus, Lafr. et D'Orb. 

 See P. Z. S. 1866, p. 190. 



(97.) Tityra albitorques, Du Bus. 



This is the true Tityra albitorques of Du Bus (Bull. Acad. Brux. 

 xiv. p. 104) ; and we are now for the first time enabled to compare 

 it with the Mexican and Central American form, which we have 

 hitherto referred to the same species. They are decidedly separable 

 as local forms ; and the northern bird, being the Psaris fraseri of 

 Kaup, may be called Tityra fraseri. It is larger than the present 

 species, has a much longer bill, and the black bar on the tail much 

 broader. 



(99.) Lipaugus lateralis, Gr. R. Gray ; Sclat. et Salv. Ex. 

 Orn. p. 6. 



In our synopsis of these birds in ' Exotic Ornithology ' we have 

 kept the present Peruvian form separate from the Brazilian L. 

 hypopyrrhus. The specimens in Bartlett's collection do not tend to 

 confirm this view, and the point requires further examination.
