Obs. The above measurements are taken from a series of examples shot in the low country or on its hill-borders, 

 representing a small type of our Serpent-Eagle inhabiting these districts. The majority of examples from the 

 Kandyan province are considerably larger, and may be fairly held to constitute a bigger race of the species, as will 

 be seen from the following dimensions, taken from several specimens : —
