The genus Gypsophila contains one remarkable bird which is confined to certain limited tracts of limestone mountains in Tenasserim. Its plumage is of the most extraordinary character, and even the very large series of this bird in the Hume Collection affords no clue to its changes. For the present I locate this genus among the Timeliinae, but I feel sure that this is not its proper place. Its place in the system must remain undetermined until its plumage from the young to the adult stage is properly understood.
In structure Gypsophila is close to Pellorneum, from which it differs chiefly in its longer rictal bristles and stronger bill. The upper plumage is squamated in appearance, owing to the feathers being margined with black.
