A glance over the right hand column will show that 
five species have been added to the list of Papuan tortoises 
since the publication in 1889 of the British Museum Catalogue 
of Chelonians ; these are the new chelydrid Devisia mythodes, 
the three chelyids Chelodina siebenrocki, Emydura mac- 
quarii, and Emydura krefftii, and the trionychid Pelochelys 
cantorii. It will also be seen that at the present time the 
number of species known to inhabit these two geographical 
areas is equal; all the indications, however, poimt tc an 
ultimate preponderance of species in the Papuan subregion, 
when that subregion shall have been thoroughly explored, 
over its more extensive southern neighbour. For instance 
the discoveries in the Fly River country of Hmydura mac- 
quarii, a typical tortoise of the southern districts of Australia, 
and in Dutch New Guinea of Emydura krefftii, a typical 
Queensland form, suggest the probability of such North Aus- 
tralian species as Chelodina expansa, Chelodina oblonga, Emydura
