5. Notes on the Anatomy and Osteology of the Indian 

 Darter [Plotus melanog aster) . ^^ Frank E. Beddard, 

 M.A., F.R.S.E., Prosector to the Society. 



[Received March 15, 1892.] 



The structure of the soft parts of both Plotus anhinga and' 

 P. melanogaster has been fairly completely described by my two 

 predecessors. Prof. Garrod ' and Mr. Forbes ^. Prof. Garrod has also 

 given a brief account of some of the peculiarities of the third species, 

 P. levaillanti, in a later paper'. So far as I am aware, the only 

 existing account of the visceral anatomy of P. melanogaster is to be 

 found in Mr. Forbes's notes upon this bird. More recently Prof. 

 Fiirbringer, of Jena, has contributed * to our knowledge of this 

 genus in his great work upon the shoulder-girdle of birds. Having 

 recently had the opportunity — afforded me by the death, on December 

 Slit of the present year, of a female P. melanogaster, which arrived at 

 the Gardens on May \ 883 — of dissecting an example of that species, 

 I have been able to make some sliijht additions to what is already 

 on record about the bird. As will be easily imagined, I have only 

 to confirm the careful work of Mr. Forbes, so i'ar as that goes ;
