Leptocoma Cabanis, Mus. Hein., i, p. 104 (1850).

Type, Leptocoma hasselti Temm. = L. brasiliana Gmelin.

I can find no good characters by which this rather large and cumbersome group can be split up into more than one genus. Shelley's five groups of his genus Cinnyris depend entirely on colour and, even in this respect, are very contradictory. There appear to be two characters which, if constant, could have been used as generic. These are, first, the presence or absence of breast tufts in the male and, secondly, the open or concealed condition of the nostrils. The first character at once separates five of our Indian forms which seem in every respect congeneric with Cyrtostomus jugularis, leaving three forms which have no tufts, minima, hasselti (=brasiliana), and zeylonica under Leptocoma. On the other hand, these two genera would each have some species with open nostrils and others with the nostrils covered with an operculum. L. zeylonica also in its life-history and general .appearance is far more allied to the Cyrtostomus group than to the thus restricted Leptocoma group. Under these circumstances I retain all our species under the genus name Leptocoma which has page priority over Cyrtostomus and Arachnechthra. This genus has a post-breeding moult of all the body-feathers, when a plumage very similar to that of the female is acquired.
