William Edwin Brooks,
Stray Feathers
(1873)
“ In the shape of the foot and proportionate length of tarsus and hind claw, to the size of the bird, C. rufula strongly resembles C. Richardi. As Blyth justly remarks, one bird is an exact miniature of the other. But C. striolata has a shorter tarsus in proportion, more slender, and the foot is of much less proportionate spread : the hind claw too is shorter, and much more curved and slender. A few dimensions here will not be out of place. ”
