This Myiobius is nearly allied to M. nevius (Bodd.) (Pl. Enl. 574, 
fig. 3) of Brazil, and of the same form and distribution of colours ; 
but it is easily distinguishable by its larger size, sooty colouring 
above, and red crest. It appears to be common on the western side 
of Ecuador, examples having been procured by Mr. Fraser at Palla- 
tanga, Babahoyo, and Esmeraldas. 
8. My1opius CRYPTOXANTHUS. 
Fuliginosus, uropygio magis olivaceo ; pilei plumis interne flavis : 
loris albis: alis nigris albo bifasciatis, tectricum majorum et 
minorum apicibus necnon secundariorum marginibus externis sor- 
dide albis : cauda fusco-nigricante, rectricum marginibus ex- 
ternis dilutioribus et harum ipsis apicibus anguste albis : sub- 
tus sordide cinereus, gutture albicantiore, abdomine flavido 
perfuso ; rostro et pedibus nigris illius mandibula inferiore 
carnea. 
Long. tota 4°5, alee 2°3, caudze 2°1, tarsi 0°6. 
Hab. In rep. Equator.

This species is closely allied to the preceding, but may be distin- 
guished by its smaller size, shorter bill, yellow hidden crest, and yel- 
lowish belly. Its discovery is also due to Mr. Fraser’s researches, 
the only examples of it I have seen having been obtained by him at 
Gualaquiza and Zamora, in Ecuador. It is included in my list of 
Mr. Fraser’s birds collected in those localities given in our ‘ Pro- 
ceedings’ for 1859*, but not named, as I was not then able to deter- 
mine it satisfactorily. 
The Tyrannide allied to Muscicapa barbata of the old authors 
—the type of Swainson’s genus Tyrannula (a name which we 
must replace by Mr. Gray’s term Myiobius in consequence of its ap- 
proaching too near to T'yrannulus)—appear to me to form a group 
distinguished by their short flat bills, gay colouring, and hidden 
bright crests. I possess examples of the following species, which I 
am inclined to arrange together under one generic name :— 
a. Myiobius.
