CALLISITTA. 609 



"Length, 140 ; wing, 78.5 ; tail, 53 ; culmen, 12.5 ; tarsus, 15." (Blasius.) 



Muscicapa tessacourhe Scopoli and M. luzoniensis Gmelin were both 



based upon Sonnerat's plate. The species was unrecognized until Platen 



collected a male in Mindanao. Blasius described this specimen under the 



name Micropus nehrkorni, suggesting the probability that it was the same 



as Muscicapa luzoniensis. Sonnerat's figure does not look much like a 



Penthornis. '
