''Xenotyphlops'' is the only genus of the family Xenotyphlopidae, comprising two species. They are found in Madagascar. ==Physical characteristics== Members of this genus are distinguishable externally from the Typhlopidae by possessing a greatly enlarged and nearly circular rostral shield. This shield is nearly vertical in a lateral aspect, as a result the two species have a "bull-dozer" appearance. ''Xenotyphlops'' species are internally unique in that (1) they lack a tracheal and (2) possess an unexpanded tracheal membrane.〔(Reptile-database.reptarium.cz ) (retrieved December 1, 2013)〕
