82 The Philippine Journal of Science 
is sustained by the condition of a male specimen of Terpsiphone 
princeps (Temm.) collected at “Hiuga-Kiushi,” Japan, on Au- 
gust 5, 1894. In this specimen the rectrices are graduated, with 
the central pair slightly narrowed; the greatest differences in 
length are as shown in Hartert’s plate of Callaeops. 
For the present I am satisfied to let Terpsiphone nigra stand 
as a synonym of Callaeops periopthalmica, but I do not feel sure 
that a long-tailed black flycatcher will not be discovered in Luzon. 
Callaeops is no more than a subgenus of Terpsiphone. 
The distribution of the species is: Batan Island, Batanes, 
resident; accidental near Manila, Luzon, P. I.
