(instead of olive-grey)i and the rectrices warm brown edged with rufescent (not 

 uniform olive-grey). Pilenm and back are, fnrthermore, more or less brightly 

 cinnamon-brown (instead of olive-grey or brownish olive), and the under parts 

 deeper ochraceons. The female from Marnins agrees very closely with Natterer's 

 hen birds, while the one from Calama is less rufescent on the back and tail, 

 pointing towards M. m. menetriesii, from which it can, however, easily be told by 

 the colonr of the upper wing-coverts, etc. 



The synonymy and range of the two races may be summarized as follows : —
