harum latioribus, extus ochracescenti-rufis : subtus valde dilu- 
tior, gula albicantiore, ventre crisso et tectricibus alarum infe-

This Tyrant-bird belongs to the crested section of the group which 
contains M. ornatus (Lafr.) and M. phenicurus, though its bill is 
slightly more compressed and less well provided with rictal bristles 
than in those species. My collection contains two specimens of this 
bird, one from Pallatanga in Ecuador, collected by Mr. Fraser 
(no. 1088), and a second received from M. Verreaux, apparently a 
Bogotan skin. The latter is either a female or young bird, and wants 
the orange crest. 
The wings of this Myiobius are rather long, reaching beyond half 
the length of the tail. The third, fourth, and fifth quills are nearly 
equal and longest, the second and sixth are of the same length, the 
first being equal to the eighth and ninth. 
6. My1osius PULCHER. 
Olivaceus, pilei semicristati plumis intus aurantiacis; loris albi- 
dis ; alis nigris albo bifasciatis, tectricum majorum et minorum 
apicibus necnon secundariorum marginibus externis conspicue 
albis aut flavicanti-albis : cauda fusca, extus olivaceo limbata: 
subtus flavus, gutture magis aurantio: tectricibus alarum infe- 
rioribus pallide sulphureis : rostro et pedibus nigris, illius man- 
dibula inferiore carnea. 
Long. tota 3-5, alee 1°9, caudze 1°6, tarsi 0°55.

This pretty and well-marked species is allied in structure to the 
last, but is immediately distinguishable by its diminutive size and 
doubie-banded wings. I have two examples of it, both out of a col- 
lection received by Mr. Gould from Ecuador, as it is believed, from 
the eastern slope of the watershed. The third, fourth, and fifth 
quills are equal and longest, slightly exceeding the second and sixth ; 
the first is rather shorter than the longest secondaries. 
7. My1opius CRYPTERYTHRUS. 
Fuliginoso-fuscus, uropygio brunnescentiore ; pilei plumis interne 
rubris ; loris albis; alis nigricantibus albo bifasciatis, tectri- 
cum majorum et minorum necnon secundariorum marginibus ex- 
ternis fulvescenti-albis : cauda fusca, marginibus pallidioribus : 
subtus albus lateraliter cinerascens, pectore nigricanti-cinereo
