This bird, of which M. Andre obtained bnt a single specimen, seems to be 

 closely allied to .1/. bumbla from Gniana and J/, alboyiihiris from Ecuador. From 

 the former it differs by having the throat whitish grey and the foreneek and chest of 

 a mnch paler grey, with bnt very slight indications of dnsky bauds ; by the abdomen 

 being very indistinctly banded with brownish cross-bars ; by the upper parts of the 

 body being of a mnch lighter and more rufescent brown, with very slight indications 

 of blackish edgings to tlic tips of the feathers ; also by the white wing-bands being 

 a little broader, and by the presence of distinct small white spots at the tips of 

 the medium upper wing-eoverts, which are altogether wanting or only indicated in 

 M. bambla. From ^f. ii/boi/ii/iiris it difters by the throat being not pure white, but 

 ]iale or whitish grey, by the shorter wing, shorter tarsus, less barred breast and 

 abdomen, and more rufescent uppersid(>.

The two skins from Perico and Maij)nres, collected by Mr. Cherrie, closely 

 resemble typical Thr. albijjeetus, but are mnch deeper rufescent on the sides of the 

 body, thighs, vent and under tail-coverts. The wing seems to be about 3 mm. 

 longer, the ujijierside, especially the rump, very dee]) rufous. 



Vs'e refrain for the present from bestowing a name on this subspecies, and we 

 trust that a review of the genus T/iri/op/iilus,hy Mr. Carl Hellmayr, which we under- 

 stand is passing through the pres.s now, will soon enlighten us on the various species 

 and subspecies of this interesting group. We may, however, mention that the 

 birds from the Peruvian Amazons (Ucayali, Pebas, etc.), which are united with 

 albipectus in Cat. Ji. Brit. M/is. vi. p. 207 (there erroneously called li'/fcotix), are 

 different again, being very dark, very short-winged, and very closely barred on the 

 wings.
