AQUILINE. 81 



Gen. PoLio^TUS, Kaup. 



C/iar.— Bill somewhat lengthened, straight at the base, com- 

 pressed, with a prominent sharp festoon ; wings short ; tail rather 

 short, slightly rounded ; tarsus feathered in front for one-third of 

 its length, stout, covered in front with large transverse scales, 

 posteriorly with some large, somewhat irregular, scales, externally 

 and internally with very small scales ; feet large, toes nearly covered 

 above with large scuta ; lateral toes nearly equal ; middle and outer 

 claws about equal, less than the hind claw ; claws rounded. 



This genus is by some included in Pandion, by others in Halicetus. 

 It is indeed osculant between the two, but I think, with Blyth, 

 worthy of a separate generic or sub-generic division. It diifers from 

 Halicetus by its shorter bill, and rounded claws ; and from Pandion 

 by its short wings, larger tail, and differently formed feet.
