I have united Hume's D. dicruriformis with this species, as I cannot find 

 any good character which would serve to give it specific rank. It is certainly 

 a larger bird, but I think with Mr. Sharpe that it can only be looked upon 

 as a race. The comparative measurements of Andamanensis and dicruri- 

 formis are as under :
