Forster, Syn. Cat. Brit. B., 1817, p. 14. Type, L. megarhyncha.
The genus Luscinia is very close both to the preceding genus Cyanosylvia and the next one Calliope but differs from both of these in having the two sexes alike. The first primary, though varying considerably in length, is always very short, measuring less than a third of the second primary which is long. The tail is long and the tarsus rather long and stout.
