ochroptila, but from the other races of the species. It differs from 

 Kittacincla malabarica malabarica (specimens from the Malay Penin- 

 sula) in its darker and more blackish throat and upper surface. It is 

 even more different from Kittacincla malabarica suavis, for it has 

 broad, brown bases to the outer rectrices, lighter, less metallic black 

 (more slaty) upper parts and throat, and lighter posterior lower parts. 



It is particularly interesting as being the only known instance of 

 a second resident form of the same species on the Anamba Islands. 

 It is apparently confined to Pulo Riabu, where Doctor Abbott says 

 that it is fairly common; and to Pulo Peling, where he observed it, 

 August 17, 1899. 



Two specimens are in the collection — the type above described 

 and an immature male, No. 170919, U.S.N.M., also from Pulo Riabu, 

 taken, August 18, 1899. This bird is just beginning to molt from 

 the juvenal into the adult plumage. The head, hind neck, and part 

 of the back are still dull clove brown; the wings lighter brown of 

 a more sepia tone, the quills rusty edged, and some of the coverts 

 with tawny spots; the tail is short like that of the female, and dull 

 colored; the sides of the head are dull brownish slate black, with 

 small ochraceous streaks; chin and throat dull brownish slate color 

 with rather large spots of ochraceous; posterior lower parts deep 

 tawny rufous, the middle of breast slightly mottled with blackish, 

 and the middle of abdomen white.
