P . perspicillata (Lath.) by Dr. Bovvdler Sharpe and others, 

 is apparently quite a different bird. The difference from 

 P. perspicillata (i. e. P. torquata) has already been pointed 

 out by the late Prof. Schlegel (Mus. Pays-Bas, Striges, p. 1 

 & note), where he remarks as follows : — ' Tres-voisine de la 

 S. perspicillata, mais d'une taille un peu plus forte et a 

 teintes plus pales/ 



" In a paper on the birds of Rio Grande do Sul, written in 

 company with Dr. von Ihering, I have also alluded to these 

 differences (cf. Berl. & Ihering, Zeitschr. ges. Orn. 1885, 

 p. 166). I have now in my collection two skins from Santa 

 Catharina, and have seen others from there, which fully confirm 

 the distinctness existing between P. pulsatrix and P. perspi- 

 cillata. The former is a larger bird, and differs decidedly in 

 its coloration as follows : — The upper parts of the body, 

 including the head and the upperside of the wings and tail, 

 as well as the throat and breast, are of a much lighter brown, 

 being light chocolate instead of blackish brown, and this 

 coloration is quite uniform in shade, while in P. perspicillata 

 the head and the upper parts of the back are always much 

 blacker than the remaining portions. The abdomen, on the 

 contrary, is of a much darker fulvous brown, while in 

 P. perspicillata it is of a pale ochraceous buff. The white 

 patch on the jugulum is but slightly indicated, and is more 

 Of a fulvous white instead of being pure white. The super- 

 ciliary stripe is not extended beyond the eyes and is by no 

 means so conspicuous, being rusty white, as are also the 

 hair-like plumes on the sides of the head, while in P. perspi- 

 cillata all these parts are almost pure white. The tail is 

 nearly uniform, the darker bands on the apical third of the 

 under surface of the rectrices being but slightly indicated, 

 while on S. perspicillata the tail-feathers underneath show 

 conspicuous whitish and blackish bands and a whitish apical 

 border, altogether wanting on P. pulsatrix.
