least to the Ecuadorian species which I identify with Tschudi's 

 wretched figure), but is smaller in size, of a brighter and uniform 

 greenish yellow below, and has the lower mandible wholly yellow, 

 and feet pale. In L. superciliaris the lower mandible is black, like 

 the upper. I have two similar specimens of Bogotan origin, and a 

 third (imperfect) from Venezuela, which may also belong to the same 

 species, though it wants the conspicuous ochraceous tippings of the 

 wing-coverts. 



7. Myiobitjs bellus. 



Obscure olivaceus, pilei subcristati plumis interne rubro-igneis ; 

 alts nigris late ochraceo bifasciatis, harum remigibus eodem 

 colore limbatis : cauda fuscescenti-cinerea : subtus flatus ; pec- 

 tore fulno tincto : rostro superiore nigro, inferior e fiavo : pedi- 

 bus plumbeis. 

 Long, tota 4*2, alee 2*3, caudae 2'0. 

 Hab. In Nov. Granada int. 

 Mus. P. L. S. 



This species of Myiobius is closely allied to the M. pulcher of 

 Ecuador (P. Z. S. 1860, p. 464), and must be placed next to that 

 species in the order in which I have arranged the genus (I. c). It 

 is, however, easily distinguishable by its larger size and larger wings, 

 though nearly alike in coloration. 



8. Empidochanes pcecilurus. 



Fuscescenti-griseus, pileo obscuriore ; loris fuscescentibus ; alis et 

 cauda nigricanti-fuscis, illarum tectricum apicibus et secunda- 

 riorum marginibus externis albescentibus : subtus pallide ochra- 

 ceus, later aliter cinerascens ; subalaribus, remigum et rectricum 

 {nisi duarum mediarum) marginibus internis latis et crisso rufis, 

 fere rubiginosis : rostro et pedibus nigris. 

 Long, tota 5*5, alse 2'8, caudae 2*3. 

 Hab. In Nov. Granada int.

This Tyrant-bird, of which I have a single specimen, is readily 

 distinguishable by its parti-coloured tail. The inner webs of all, 

 except the medial pair, are broadly margined with clear rufous. This 

 colour increases towards the base, and gradually occupies the whole 

 of the vane. The outer tail-feather is also narrowly margined with 

 the same colour. The under wing-coverts and inner margins of the 

 quills are likewise similarly coloured. The fourth primary is rather 

 longer than the third, which slightly exceeds the fifth, and longest ; 

 the second is slightly shorter than the third, the first being of about 

 the same length as the eighth and ninth. 



This bird has much the general appearance of an Empidonax, 

 though abnormal in colouring. I place it for the present as a second 

 species of the allied southern genus Empidochanes, of which the type 

 is Muscicapa oliva, Bodd. (PI. Enl. 574. fig. 2). This generic term 

 I propose to use in the place of Myiophobus of Cabanis and Heine,
