INSESSORES. 243 



coasts of Australia, in which localities specimens have been 

 procured by Sir George Grey and by Gilbert, the latter of 

 whom states that it is abundant in all parts of the Cobourg 

 Peninsula, and that it is to be met with in every variety of 

 situation, that it is usually seen in pairs, and that it secludes 

 itself during the heat of the day amidst the dense thickets of 

 mangroves. 



A nest found by Gilbert in the early part of November 

 appeared to have been recently inhabited by young bu'ds ; it 

 was placed in the centre of three upright twigs of a species of 

 Banksia, and was formed of narrow strips of bark, firmly 

 bound together on the outside with cobwebs and vegetable 

 fibres ; it was very cup-like in shape, about two inches and a 

 half in height, one inch and three-quarters in diameter, and 

 three-quarters of an inch in depth. 



The food consists of insects of various kinds and then' larvae. 



All the upper surface dull brown ; wings and tail darker 

 brown, the outer feather of the latter on each side margined 

 externally and largely tipped with white, the next having a 

 large irregular spot of white at the tip, and the next with a 

 minute line of white near the tip ; chin and under sm-face 

 buffy white, with an indication of a dark brown band across 

 the chest ; bill and feet black. 



Total length 8 inches ; bill f ; wing 3f ; tail 3^ ; tarsi xe . 



Genus SAULOPROCTA, Cahanis. 



M. Cabanis has considered it desirable to separate the 

 MMpidura motacilloides of Vigors and Horsfield and one or 

 two other nearly allied birds from the smaller BhijjidurcB and 

 to form them into a distinct genus, believing that their greater 

 size, longer wings and legs, and different style of colouring 

 justified his so doing. 



Besides the two species found in Australia several others 

 exist in the islands lying to the northward of that country, 

 all of which bear a general resemblance to each other.
