Mus. P.L.S. 
Two examples, not in good condition, of this apparently unnoticed 
species of Myiarchus ; of the size and general structure of M. feroa, 
but recognizable by its pale, rather greyish, olive back and dusky- 
grey head.

57. MytorHosus 
Two species of this division of T'yrannide@ (as typified by M. vir- 
gatus) are in the collection. These, with others of this very difficult 
group, I must leave for future determination. 
58. PyrocEPHALUS NANUS, Gould? 
Numerous examples of a Pyrocephalus, which agree with the 
description of P. nanus in having the outer margins of the external 
rectrices and tips of all “light grevish-brown.”: It does not, how- 
ever, seem to be inferior in size to the Eastern species, as far as I am 
able to judge by the specimens in my possession. 
59. Myrosrus BarBatus (Gm.). 
Two ex., apparently not different from the Eastern bird. 
60. CycLORHYNCHUS SUBBRUNNEUS, Sp. Nov. 
Brunnescenti-oleagineus : alis nigricantibus, fulvescenti-brunneo 
extus marginatis: cauda rufescenti-fusca unicolore: subtus 
pallide cineraceus, olivaceo perfusus, gutture et ventre medio 
dilutioribus :. tectricibus subalaribus fulvescentibus : rostro 
superiore nigro, inferiore flavo : pedibus plumbe?s. 
Long. tota 7°5, alee 3:4, caudz 3°2. 
Hab. In rep. Equator. 
Two ex. “ Irides whitish.” This Tyrant may, I think, be well 
placed in the genus Cyclorhynchus, although not a typical member 
of the group. The bill is much more elongated than that of C. oli- 
vaceus, and not so broad at the base, but does not differ in propor- 
tions from that of C. faviventris. The third and fourth primaries 
are nearly equal, and longest in the wing ; the fifth is slightly shorter; 
the sixth nearly of the same length as the second. 
61. MusctivoRA OCCIDENTALIS, sp. nov. 
Mr. Fraser has sent three specimens of a Crowned-Tyrant from 
Babahoyo, which will probably require a new name, as being distinct 
from the species at present known. It differs from Muscivora regia
