BIRDS OF THE ANAMBA ISLANDS. 55 
Juvenal female, No. 171089, U.S.N.M.; Pulo Jimaja, September 
23, 1899. Length, 111 mm. “‘Iris yellow brown; feet fleshy 
brown.” 
Although the number of adults is too few to admit of a perfectly 
satisfactory comparison, they seem to be identical with birds from 
the Malay Peninsula which represent true Orthotomus atrogularis. 
The adult female is like the adult male, except that the black gular 
patch is much less extensive and broadly streaked with white. 
The two youngest juvenal males (Nos. 170970 and 171001, 
U.S.N.M.) resemble the adult female, but have rather duller, lighter 
upper parts, particularly the pileum, with a mixture of olive green 
in the pileum; less black on the jugulum, and a wash of olive yellow 
across the breast. 
The juvenal female is like the juvenal male, but entirely lacks the 
blackish on the jugulum and the olive yellow wash on the breast; 
the crown and forehead of one (No. 170969, U.S.N.M.) are entirely 
olive green like the back, save for one half-grown rufous feather; 
the forehead and sides of crown of the other (No. 171089, U.S.N.M.) 
are rufous, but the rest of the pileum is olive green. 
The adult male (No. 171002, U.S.N.M.), taken, August 25, 1899, is 
in heavy molt of contour feathers and is also molting some of the 
wing-quills; and the adult female (No. 170968, U.S.N.M.), taken, 
August 20, 1899, is in the same condition. One of the juvenal males 
(No. 171025, U.S.N.M.), taken, August 29, 1899, is passing from the 
juvenal plumage into that of the first autumn, and has acquired the 
rectrices, nearly all the remiges, and approximately three-fourths of 
the contour feathers. The two other juvenal males (No. 171001, 
U.S.N.M., August 25, 1899; and No. 170970, U.S.N.M., September 5, 
1899) are just beginning to change from juvenal into the first autumn 
livery; and one of the juvenal females (No. 170969, U.S.N.M.), taken, 
August 21, 1899, is in the same condition. The remaining juvenal 
female (No. 171089, U.S.N.M.), taken, September 23, 1899, has 
apparently rather more than half completed the change to first 
autumn plumage. 
Doctor Abbott found this tailor-bird common on Pulo Siantan from 
August 19 to September 6, 1899.
