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 Orihotomus 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. 



Family GRACULIDAE. 



GRACULA JAVANA PRASIOCARA, new subspecies. 



Subspecific characters. — Similar to Gracula javana javana, from 

 Java, but larger; sides of crown more greenish.
