black, more or less overlaid with canary yellow; ‘‘iris dark reddish 
brown; bill black above, leaden beneath; feet blue; claws black.” 
The female of this new form, compared with a female of Aegithina 
euidissyma from Pulo Lankawi, western Malay Peninsula, is very 
much more yellowish below. 
Three specimens were obtained by Doctor Abbott, as follows: 
Adult male (type), No. 170951, U.S.N.M.; Pulo Siantan, August 
20, 1899. “Iris dark reddish brown; feet blue; claws black; bill 
black above, leaden beneath.”’ 
Adult male, No. 170952, U.S.N.M.; Pulo Siantan, August 21, 1899. 
‘Feet blue leaden; bill black above, leaden beneath.”’ 
Adult female, No. 170953, U.S.N.M.; Pulo Siantan, September 5, 
1899. ‘Feet blue; bill leaden blue, culmen and tip black.” 
The type has some of the wing-quills in process of molt, so that its 
true wing measurement is possibly somewhat greater than that given 
below. Doctor Abbott states that this species lived in the forest, 
and was tolerably common on Pulo Siantan from August 19 to 
September 6, 1899. ,
