_Plotus nanus_ Newton and Gadow, Trans. Zool. Soc. XIII p. 288, pl.
XXXIV figs 1-5. (1893).
The humerus, the pelvis with sacrum, and the tibia were the materials on
which our authors founded this new species. They state that all the
strongly developed characters in these bones leave no possible doubt as to
its being a species of _Plotus_, and its diminutive size at once
distinguishes it from the three known species--_P. anhinga_, _P.
melanogaster_, and _P. novaehollandiae_.
