The only pair seen. 
This extremely rare Green Bulbul, one of the handsomest 
of its genus, is to the best of our knowledge only known from 
the three types in the Leyden Museum, two of the typicat 
series in the Liverpool Museum, six collected by Modigliani in 
' the Battak Highlands and two males from the Padang High- 
lands, collected by Klaesi.

“‘Tris carmine, bill and feet black.” 
We can say with some certainty that this species does not 
occur in the Korinchi Valley, though, judging by the very 
large number secured by Klaesi in the Padang Highlands to 
the north of Korinchi Peak, it is extraordinarily abundant 
there. 
The four nominal species of this genus occurring outside 
the Philippine group are extremely closely allied and consti- 
tute but slightly differentiated races. It is impossible to pick 
out by the tint of the blue of the upper surface specimens of 
I. puella, I. cyanea and I. criniger, when considerable series of 
these forms are mixed, and as the synonymy shows, the Suma- 
tran bird has at different times been referred to each of the 
four races. The length of the upper and lower tail coverts 
which in fully adult West Sumatran males seem always to 
reach the extreme tip of the tail is the only character by which 
they can be separated from the Malayan I. puella and I. 
cyanea, Buttikofer, however, states that birds from Deli in 
Part Il: Vertebrata.
