PLOTUS NANUS NEWT. & GAD. 



Plotus nanus Newton and Gadow, Trans. Zool. Soc. XIII p. 288, pi. XXXIV figs 1-5. 



HE humerus, the pelvis with sacrum, and the tibia were the materials 



X 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. 



The measurements are as follows : — 



(1893). 



Left humerus, length 89 mm. 



Left tibia, length 61 „ 



Distance from acetabular axis to anterior end of sacrum 30 mm. 

 Distance between ventral inner margins of the acetabula 14-5 mm. 

 Habitat : Mauritius. (Also recorded from Madagascar.)
