here for the first time described from a species indigenous to 
the eastern hemisphere. was primarily intended to be the full 
aim of this paper, and naturally is still its chief consideration, 
it has occurred to me that an analytical list of all the species 
at present known to inhabit New Guinea, written in a concise 
and intelligible form, would be of great advantage to zoologists 
and collectors in that country, where the opportunities of 
consulting works of reference are few and far between. A 
secondary object which I have in view in so greatly enlarging 
the scope of this paper is to stimulate local observation and 
encourage explorers and others—traders, miners, etc.— 
whose occupations bring them in touch with the inland dis- 
tricts, to make more careful inquiries concerning the testudinian 
fauna and more extensive collections of the various species, 
most of which are known to science from a few specimens 
only.* I would especially draw their attention to the two 
*The testudinian reptiles lend themselves beyond all other chordates 
to amateur collecting, since, though the entire animal is necessarily more 
valuable to the scientific student, the easily preserved shell {carapace and. 
plastron) is the most important factor in the differentiation of species.
