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 Aegitliina 

 viridissima 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.
