The Chittagong Croton is, or probably was, a small tree that was found once in 1939 at a place named Myanimukh on a slope of a forested hill in the Chittagong Hill Tracts, a province in eastern Bangladesh.
The species was described in 1983; it has never found since the type collection and might well be extinct.
The enigmatic braman Frog is known exclusively from a single illustration (shown here), which, however, may or may not correspond to a specimen that is kept in the National Museum of Natural History in France.
The species is believed to originate from an area somewhere between Bangladesh and India.
The Braman Frog may actually never have existed as a distinct species, however, I’d like to list it here as well, since it’s name often appears in listings of extinct animals.
