Ixxxvill INTRODUCTION. 
Genus Heroptias, Bove. 
Nearly every part of the globe is tenanted by members of this genus. Those inhabiting Australia are very 
nearly allied to, but I believe are quite distinct from, the species found in India, Europe and America, and of which 
they are the Australian representatives.

Genus Nycricorax, Steph. 
Europe, Africa and America are all inhabited by Night Herons; consequently it is one of the most widely- 
distributed sections of the family. 
The single Australian species of this well-defined genus is rendered conspicuously different from all other 
known species by the cinnamon colour of its back.

“Shot at Cape York and Port Essington, in which latter place it is rather abundant. Yangko of the Cape 
York aborigines, Alawool of the Port Essington natives.” —J. M‘Gillwray. 
Genus Boraurus, Steph.

The Australian Bittern is very similar to the European, B. stellaris. 
Genus Arperta, G. R. Gray. 
The members of this genus of Mangrove Bitterns usually frequent the extensive belts of mangroves and low 
dells covered with reed-beds and dense herbage. 
Africa and America are each inhabited by birds of this form, one species of which is also found in Europe, 
several in India and the adjacent islands, and three in Australia, viz.— 
521. Ardetta flavicollis , . P P ; ; ; ; ; . . ; : Vol. VI. Pl. 65. 
This species is said to inhabit Java and India, and although I have figured it under the name assigned to the 
Indian and Javanese bird, I am still inclined to believe that it is distinct.

This species, with the little Bittern of the British Islands and several others inhabiting Africa and America, 
would admit of being separated into a distinct genus.
