A specimen from Vera Paz, Guatemala, which I take to be true M. brachi/tarsus, 

 differs from all the last-named birds in having the pileum of a much browner and 

 the back of a more greenish shade (less blackish on the head and less greyish on 

 the back), and in having the middle line of the breast of a pure yellowish white 

 with no greyish suffusion, the sides of the breast being also more brownish, less 

 greyish. A Bogota skin seems to agree best with the bird from Guatemala. 



As far as I can see, Bonaparte's description of his Planchesia Juliginosa, 

 based on specimens collected in Cayenne by M. Deplanches, agrees with Cherrie's 

 specimens ; nevertheless an examination of the type-specimen in the Museum at 

 Caen is most desirable. In the case tliat Planchesia fuliginosa Bp. is identical 

 with our species, the generic term Myiockanes Cab. & Heine would become a 

 synonym of Planchesia Bp. 



Muscicapa fuliginosa Gml. ex PI. Enl. 574. f. 1 (=: Masricapa arausia 

 V. L. S. Mull.) seems to be quite a dilfereut bird. At least I am unable to recognise 

 our Myiockanes in the " Gobe-mouche bruu de Cayenne " of Buffon and Daubenton.

The Empidochanes from Cayenne has the npper parts of a very dark 

 coloration, being blackish brown or smoke-brown instead of rufous-brown as in 

 true E. fuscatus from Bahia. The mandible is also darker, more blackish than 

 iw E. fuscatus. The rufous wing-bands are generally narrower and darker, more 

 olivaceous rnfous-brown instead of clear rufons-brown. 



Specimens from Para agree perfectly with the Cayenne birds, while specimens 

 from the Upper Amazous (Yquitos) and from Alta Gracia on the Orinoco differ in 

 having the abdomen nearly white, but slightly tinged with yellowish. In this way 

 they agree with E. f. himaculatus (Lafr. & D'Orb.) from Bolivia and Mattngrosso, 

 but have the upper parts much darker, just as in the Cayenne bird. 



E. f cabanisi (L^ot.) from Trinidad, coast region of Venezuela and Colombia 

 (Bogotd collections), has the upper parts of a much clearer olivaceous-brown. It 

 agrees with E. f fumosus in having a blackish mandible.
