g. A somewhat older female than "/." 



Simgei Kilim, Langkawi, 23rcl February, 1909. 



Very similar to ''//' but with the shouldeis darker and 

 ■without the pronounced white margins to the median wing- 

 coverts, though this may be clue to the age of the feathers ; 

 sides of the head somewhat richer buff. 



Wing 12'7 ; tail 9*2; tarsus 1'6 ; bill from gape 1'25 ; 

 crest 1*9 inches. 



h. A female exactly resembling '' g."

Wing 12'9 ; tail 9"G ; tarsus 1'65 ; bill from gape 1"3;

i. A female, probably immature. 



Interior of Sumatra [Wallace Cull.). 



Like the other feinules, except that the cross-bars on the 

 belly are less clearly defined, while the gular stripe is entirely 

 lacking. 



Wing 12*4<; tail 9*0; tarsus 1*6; bill from gape IS;

It may therefore be fairly concluded that the females in 

 this species differ from the males in the pale head with buff, 

 and not grey sides, and in the more rusty, less brown bars 

 on the under surface. There is a slight difference in size in 

 favour of the female, but this is by no means marked, and 

 in the small series before us may be due to the influence of 

 locality and individual variation. 



The specimen of Baza ceylonensis Leggc, from near Kandy, 

 in the British Museum can be exactly matched except in 

 size by two of the above-described series of females, and there 

 is but little doubt that the form is at best merely a poor 

 subspecies of B.jerduni. The dimensions of this specimen, 

 which is a female, are : — "Wing 12"0 ; tail 8*5 ; bill from 

 gape 1*2 5 ; crest 2'4 inches. 



The Bornean bird, B. borneensis Bruggem. (Sharpe, ' Ibis,' 

 1893, p. 557), is quite a good species, distinguished by its
