CALLISITTA. 609 
“Length, 140; wing, 78.5; tail, 53; culmen, 12.5; tarsus, 15.” (Blaswus.) 
Muscicapa tessacourbe 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.

toothed; culmen but very slightly curved; nostrils oval, nearly hidden

somewhat curved ; first primary equal to about one-third of second ; fourth
