REMARKS. This dark form, closely resembling P. p. varicgatus in 

 coloration, but perhaps never quite so intensely blaek below, and 

 with the rump apparently never so black as the back, can always be 

 distinguished from P. p. varicgahis by its Ynuch larger size. Both young 

 and adult are sometimes uniformly colored below and sometimes very 

 much freckled with grayish. 



A specimen (Carnegie Museum) from Macho Muerto, Dept. Oran. 

 N. Argentina, has distinct whitish lores, while another (Carnegie 

 Museum) from the same locality, collected in the same year and 

 month, has practically no trace of any. In most specimens, however, 

 a very faint trace of white may be detected in the loral region. 



When Brewster and the senior author (he. eit.) separated this 

 large southern form as Pachyrhamphus notius, they compared .their 

 type with specimens of the pale race inhabiting eastern Brazil, which 

 they regarded as true poli/chopterns, but they did not fix the type- 

 locality of the latter. A few years later Hellmayr (he. cit.), evidently 

 considering the southern Brazilian bird different from true notius, 

 applied to it the name polychopterus of Spix, designating South Brazil 

 as type-locality. Notwithstanding this formal designation of the
