^Pulsatrix pulsatrix pulsatrix (Maximilian): According to Berlepsch (Bull. 

 B. O. C, XII, 1901, p. 5) this is quite distinct from P. perspicillata Latham. P. p. 

 pulsatrix is larger and the upper parts, head, throat, and crest, are much lighter 

 brown (light chocolate instead of blackish brown) and quite uniform in shade, while 

 in P. perspicillata the head and upper parts of back are much blacker than the 

 remaining portions. The abdomen of pulsatrix is dark fulvous brown (not ochraceous 

 buff as in P. perspicillata) and other characters. 



^ Pulsatrix pulsatrix sharpei (Berlepsch) : Somewhat larger than P. melanota 

 (Tschudi) and differs from it in having the belly pale fulvous brown with almost 

 obsolete darker bands (instead of belly whitish with dark brown bands) ; upper parts 

 more chocolate brown (not so socty brown) ; the pale patch on middle of chest and 

 the superciliary stripe is fulvescent (instead of nearly white) and other characters.
