It is only fair to state that M. Oiistalet had already recognised the true position 

 of this remarkable bird, as I learn from a M8. note of his on the bottom of the 

 i-tand. 



The iyyiG specimen has no locality, but M. Onstalet suggested that it might have 

 come from the interior of Cayenne, which is almost entirely unknown. 



The following key to the species of Huterocefcus may be acceptable to 

 ornithologists : 



A. With a brightly coloured crest (t?c?)- 



a. Forehead and sides of the crown very different 



from the olive-green colour of the back. 



a'. Crown-patch fiery red, forehead and sides 



of crown black ; breast chestnut . . Il.Unteatusi^incW.) 

 a". Crown-patch lemon-yellow, forehead and 



sides of crown ashy grey ; breast and 



abdomen pale sulphur yellow . . //. b.iteoceplialns (Less.) 



b. Forehead and sides of the crown olive-green 



like the back, 

 a'. Crown-patch golden yellow ; breast 



chestnut-brown, decidedly darker in 



colour than the abdomen . . . H. jlamvcrtex Yeiiz. 

 a^. Crown-patch orange, breast and abdomen 



of a uniform pale ochreous reddish . H. aurantiivertex Scl. 



& Salv. 



B. No bright crest ( ? ? ). 



c. Throat white with a slight isabelline tinge ; 



upper parts dull brownish olive-green . . //. linteatus (Strickl.) 

 (I. Throat pale grey ; upper parts pure olive- 

 green ........ H.Jlavimrtex Pelz. 



26. Muscicapa luteocephala Lafr. = Neopelma aurifrons (Wied). 



Musc'icapa aurifrons Wied, Beilr. Xnturg. Brazil, 3. ii. (1831), p. 829 [" Camnmu and Bahiii'']. 

 Muscica2M hiteocephalii. (nee Lesson 1831 !j Lafresnaye, Marj. Zoid. 1833. cl. ii. tab. 13.

 M.S. Hilaire, aodt 1822. Muscicapa luteocephala Lafresnaye." AVing 68^; tail 

 62 ; bill 10 mm. Not different from specimens from S. Paulo. 



As pointed out by Pucheran, the " Muncicapa luteocephala " of Lafresnaye is 

 very diiferent from Lesson's species. Lafresnaye's name has been quite correctly 

 given as a synonym of ^1/. aurifrons in tlie Cat. Birds, xiv. p. 323. 



27. Psaris erythrogenys Selby should be Tityra inquisitor erythrogenys (iSelb) ). 



Psaris er/jtliriii/riii/.'s Selby, Znnl, Jnurii. ii. uo. viii. (January — April 1S2IJ) p. 483 [Pernjimbuco. —

 J. Verreanx, Bresil," and on the bottom of the stand I find the note: "de Pernambuco, 

 fichange b. M. Verreaux, 1823. Brt^sil, no. 3593," Wing 04 ; tail 62 ; bill 

 2U mm. 



This is undoubtedly the type of Psaris erythrogenys. Selby says expressly 

 that he described an example from Pernambuco in the Paris Museum, and 



• Minas Geraes.
