No species'of the genus Ariamus seems to enjoy a wider range 

 than A. leucogaster, being found alike at Cape York, and in 

 Victoria and South Australia. It is J generally Jfound in the 

 vicinity of watercourses, relining the deserted nest of Grallinapicata 

 wherein to deposit its eggs. Only on one occasion have I Heard 

 of this bird building a nest for itself, and that was found by 

 Mr. K. H. Bennett at Ivanhoe ; it was a loosely built structure 

 of dried grasses placed in the horizontal fork of a small tree over 

 hanging water. Eggs three in number for a sitting, of a dull 

 white, spotted and blotched with faint markings of yellowish- 

 brown, reddish-brown and obsolete markings of bluish-grey, the 

 latter appearing as if beneath the surface of the shell ; these 

 markings usually assume the form of a zone at the larger end. 

 Dimensions of a set of three taken by Mr. Bennett on the 18th of 

 October, 1885 are as follows, length (A) 0-9 x 0-63 inch ; (B) 

 0-95 X 0-63 inch ; (C) 0-9 x 0-62 inch. 



October and the two following months constitute the breeding 

 season of this species.
