Genus Nycticorax. 
The single Australian species of this well-defined genus cannot 
by any possibility be confounded with either of those inhabiting 
any other part of the vrorld ; the cinnamon colour of its back ren- 
dering it conspicuously different from all known species. 
Europe, Africa and America are all inhabited by Night Plerons, 
consequently it is one of the most widely-distributed sections of the 
family.

“ Shot at Cape York and Port Essington, in which latter place it 
is rather abundant. Yangko of the Cape York aborigines, Alawool

Genus Botaurus.

The Australian Bittern is very similar to the European species _£?. 
stellaris. 
Genus Ardetta. 
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 fiavicollis ......... Yol. YI. 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.

523. Ardetta stagnates, Gould Vol. YI. PL 67. 
524. Ardetta pusilla Yol. VI. PL 68. 
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.
