irrigated districts. It extends into Assam and Burmali. It 

 usually watches for its prey from a high tree, or sails slowly over 

 the fields and woods. It lives chiefly on snakes, also on lizards, 

 rats, large insects, and frogs. According to Mr. Blyth, it clutches 

 these last out of the mud of shallow tanks, and its toes are very 

 often covered with mud. It has a plaintive wild cry. It breeds 

 on trees, making its nest of sticks ; and lays two dirty white 

 eggs, with a few dark specks. 



Other species of Crested Serpent Eagles are S. Bacha of Daudin, 

 (F. bido, Horsf.,) from Java and Sumatra ; aS. spilogaster, BL, from 

 Ceylon, and perhaps from S. India ; and S. liolospilas, Vio-ors, 

 from the Philippines. The first of them is figured by Levaillant, Ois. 

 d'Afrique, pi. 15, and was long thought to be African. But it 

 does not occur in any of the authentic lists of African birds, 

 though M. du Chaillu, the Gorilla-slayer, has it in his Fauna of 

 Equatorial Africa. M. Le Vaillant, indeed, gives a long account 

 of its habits, asserting it to be a great killer of the cape conies, 

 ( Hyrax capensisj and even syllabizes its cry; but I fear alas! 

 that this does not prove its authenticity as an African bird any 

 more than du Chaillu's insertion of it in the list of birds obtained 

 by him. V. ' Ibis' vol. 2, for a critique on Le Vaillant's Birds 

 of Africa.
