g. A somewhat older female than {< f” 
Sungei Kilim, Langkawi, 23rd February, 1909. 
Very similar to “//’ bat with the shoulders dai?ker and 
without the pronounced white margins to the median wing- 
coverts, though this may be due 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 P9 inches. 
h. A female exactly resembling “ g.”

Wing 12*9 ; tail 9*6; tarsus L65; bill from gape 1*3; 
crest 2*0 inches. 
i. A female, probably immature. 
Interior of Sumatra ( Wallace Coll.), 
Like the other females, 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 gapel‘3;

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 Legge, 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.jerdoni. The dimensions of this specimen, 
which is a female, are :—Wing 12*0; tail 8*5; bill from 
gape 1*25 ; crest 2*4 inches. 
The Bornean bird, B. horneensis Bruggem. (Sharpe, 6 Ibis/ 
1893, p. 557), is quite a good species, distinguished by its
