This appears to be nearly allied to A. stentoreus, differing from 

 that species only in being of slightly smaller size, and in having 

 a proportionally shorter tail. It would scarcely be deserving of 

 specific rank hud it not become isolated in its geographical distri- 

 bution. It is of exactly the same colour as the three preceding 

 species, and is apparently subject to the same seasonal changes. The 

 legs, feet, and claws are dark brown. Length of wing 3'0 to 2*9 

 inches, tail 2-75 to 2-55, culmen 1-0 to 0-95, tarsus 1-05. Third and 

 fourth primaries nearly equal and longest ; second primary inter- 

 mediate in length between the sixth and seventh. 



So far as is known, Kittlitz's Great Heed- Warbler is confined to 

 Ponape or Pinnipet, one of the more easterly of the Caroline Islands, 

 where it is said to be a resident species.
