(syn. Turdinus Ϯ Greyish Limestone-babbler T. crispifrons) Gr. γυψος gupsos chalk; φιλος philos lover; "Genus GYPSOPHILA*, Oates ... LIMESTONE THRUSH-BABBLER ... *I propose this generic name for the bird hitherto known as Turdinus crispifrons. Neither its structure nor its coloration permit it to be placed in any genus known to me" (Oates 1883); "This Turdinus is entirely confined to the ranges of limestone rocks that occur in Tenasserim. They are found singly, or occasionally in pairs, but more often in small parties about the rocks from their bases to their summit, and never wandering away from the rocks even for a few yards ... When shot, unless killed outright, they at once scramble into one of the numerous holes or crevices with which these rocks are everywhere honeycombed, and are of course lost. They are not shy birds, and from the limited nature of their habitats are not difficult to procure" (Davison in Oates 1883).
