uuder-surface serves to distinguish it at a glance. In the northern race * the back 

 is much darker sooty grey, being little, if anything, lighter than the crown ; the 

 whole under surface, from the chin to the anal region, is uniform sooty grey 

 [very nearly as dark as the upper parts], the under tail-coverts only being edged 

 with whitish. 



Count Berlepsch f has united Contopus brachyrhynchus Cab., \ from N.W. 

 Argentine, with M. f. fumigatus, as defined above. In fact, when studying the 

 type, forwarded by the authorities of the Berlin Museum, in company with the 

 Count several years ago, I could not perceive any material difference between 

 the Bolivian series and the Tucuman bird. However, it should be noted that the 

 type specimen of C. brachyrhynchus, in bleached breeding plumage, is not quite fit 

 for the purpose of comparison. Since that time I have had the opportunity of 

 examining five adults from the mountains of N.W. Argentine, and they appear to 

 me to represent another recognisable form, characterised by its very pale colora- 

 tion. The nape, back and sides of the head, instead of being sooty grey, are light 

 smoke-grey tinged with olivaceous, the crown nearly concolour with the mantle ; 

 the throat is more whitish ; the breast much paler greyish, and the yellowish white 

 area in the middle of the belly far more extended. The wings are apparently 

 somewhat longer (98 101 mm.). 



There are, thus, three races to be distinguished : 



(a) Myiochanes fumigatus ardosiacus (Lafr.) || the darkest, ranging from 

 Central Peru through Western Ecuador to Colombia, Western Venezuela (Merida) 

 and British Guiana (Roraima). 



(b) Myiochanes fumigatus fumigatus (Lafr. & D'Orb.), lighter, with whitish 

 admixture on throat and middle of belly, inhabiting the highlands of Bolivia. 



(c) Myiochanes fumigatus brachyrhynchus (Cab.), the palest, occurring in the 

 high mountains of North-Western Argentine (Tucuman, Jujuy). 1[ 



The recently described Myiochanes ardosiacus polioptilus Todd, ** from the 

 Venezuelan coast-mountains which I have not seen appears to be a fourth 

 member of this group, and should be called M. fumigatus polioptilus Todd.
