166 BIRDS FROM NIAS. 



ready called the attention to the inferior size of the specimens 

 from Nias, without separating them from K. javariensis , 

 probably from fear that the two specimens collected by 

 Modigliani might not be fully adult birds. As our two 

 specimens (male and female) are undoubtedly adult birds 

 with dimensions strikingly inferior to those of K. javanensis, 

 I do not hesitate to consider them as specifically distinct. 

 I compared our two birds with one specimen from the 

 Indian Continent, one from Malacca, five from Sumatra, 

 one from Banka, two from Borneo and 11 from Java, of 

 which the table of measurements (in centimeters) is as 



follows :
