More satisfactory material from Java than was previously avail- 

 able proves that the bird inhabiting this island is one of the more 

 brownish races, and not identical with that from the Philippine 

 Islands or the islands of Polynesia. This race probably occurs on 

 some of the neighboring islands, although we have seen no other 

 than Javan specimens.
