Dr. Hartert ha^ suggested (Bull. Brit. Orn. Club, 

 XXXAMII. 1918, p. 71 that the comparison of a sufficient 



series of Sumatran examples with bin]- from the Malay Pen- 

 insula may show differences which would render available the 

 use of I), croceoventre Vig., as a name for the Sumatran form. 

 We find, however, that a series of seven Sumatran males which 

 we have before us can be exactly matched out of a series of 

 forty Malayan bird- : and that the character of lightness or 

 darkness of the throat is useless as each series exhibits a con- 

 siderable amount of variation : neither does a single Bornean 

 male differ from the darker-throated Malayan and Sumatran 

 examples.
