This bird agrees well with von Pelzeln's description, except that the cross- 

 bands of the tail-feathers are white, tinged with pale greyish brown on the outer 

 webs. In general coloration this species bears a strong resemblance to S. hylopkilum 

 (Temm.) from S.E. Brazil, and S. albitarse Scl. from the mountains of Merida 

 and Colombia, but differs at a glance by its more blackish upper parts, there 

 being but narrow wavy lines of dull rufous ; by the much darker rufous facial 

 ruff ; by the white (not ferruginous) tail-bands ; and by having no transverse 

 markings whatever on the abdomen. The thighs, too, are much darker, deep 

 tawny (instead of buff), etc., etc.

 bill greyish green." — Wing 167 ; tail 90 ; bill 20J mm. 



This bird agrees perfectly with several specimens from Eastern Ecuador. 

 Cassia's account and figure leave not the slightest doubt that he described the 

 species afterwards named S. usta by Mr. Sclater (cf. also Berlepsch, Bull. B. O. C. 

 xii. 1901. p. 10). 



It is scarcely to be understood why Mr. II. B. Sharpe* should have treated 

 it as a "subspecies" of Pisorhina choliba (= his Scops brasilianus), since a 

 geographical form of the latter, P. c. cruciyera (Spix), occurs in the same district 

 where P. watsonii is met with. 



This species may be distinguished by the much longer ear-tufts, which are 

 almost uniform black, with only a i'vvf minute dots of buff along the inner 

 web of the feathers. The pileum is also mainly blackish, the back and tail 

 are much darker, blackish brown, with very narrow buff vermiculatious : the 

 upper wing-coverts entirely lack the large buff spots so conspicuous in P. c. 

 crucigera and allies ; and the lower parts are deep fulvous (not white with buff 

 patches), etc., etc. 



Some specimens show a distinct nuchal collar of bright buff. The Tring 

 Museum also possesses two adult birds obtained by Mr. E. Andre near Snapure 

 in the ('aura valley, Venezuela.
