Elseya.

E. dentata.

The late Dr. Elsey, who accompanied Gregory's expedition, discovered this species in the Northern rivers. The Australian Museum has specimens from the Burnett and some from the Port Curtis District.

E. latisternum.

Closely allied to the last; both may be distinguished from other Australian Tortoises by a pair of tubercles or beards on the chin. This closes the fresh-water species as far as they are known to us at present; there is no doubt, however, that more exist in Australia. A few undescribed forms are even now in the Australian Museum collection.
