The Babblers of this genus form a connecting-link between Trochalopterum and the genera already dealt with and Argyx and Turdoides, being on the whole nearer the latter than the former group. The wing is short and rounded, the tail long and much graduated. The ball is rather slender, slightly curved, and in length about equal to, or longer than, hind toe and claw together. The rictal bristles are strong and of considerable length, and the oval, exposed nostrils are overhung by numerous hairs.
There are several species of this genus found on the borders of the Indian Empire, of which three enter our limits, whilst others may possibly be found to do so in extreme Northern Burma when the ornithology of that country is better known.
