This remarkable Bush-Robin is one of Mr. Goodfellow’s 
most important discoveries in the highlands of Formosa. As 
may be seen from the figure (PI. IV.), the style of coloration 
in the male is so absolutely different from that of any other 
member of the genus that we were at first inclined to think 
that the bird would prove to be generically distinct from 
Tanthia, but in all its structural characters it agrees well 
with other species of that genus.
