 the breast lemon chrome; abdomen, sides, and flanks, black with blue 

 and purple gloss; crissum dull black; lining of wing fuscous black,

The specimens obtained by Doctor Abbott are: 



Adult male (type), U.S.N.M. No. 174856, Brian Island, near 

 Sirhassen Island, May 31, 1900. Length in flesh, 143 mm. 



Adult female, U.S.N.M. No. 174857, Brian Island, near Sirhassen 

 Island, May 31, 1900. 



Although Doctor Abbott sent only these two examples from the 

 Natuna Islands, they show the same characters for subspecific separa- 

 tion as do the birds of a large series from Borneo, when compared 

 with a good series of the typical race from the Malay Peninsula, 

 Sumatra, and Java. The geographical distribution of this new sub- 

 species includes the Natuna Islands, Borneo, and at least the islands 

 along the eastern coast of Borneo. Doctor Hartert has recorded it ^^ 

 from Bunguran Island, under the name Chalcostetha insignis. 



Measurements are given in Table 38.
