THE VICTORIAN NATURALIST. 13 



successful in obtaining several fine examples during his trip with 

 the Calvert Exploring Expedition, has recently been found 

 nesting in the same locality as he procured his specimens. 

 During the first week of February, 1899, Mr. E. J. Harris took an 

 egg of this species from a small cup-shaped nest built in the 

 drooping leafy twigs of a Bauhinia about ten feet from the 

 ground, and close to the junction of the Fitzroy and Margaret 

 Rivers, North-west Australia. It is oval in form, gently tapering 

 towards the smaller end, and is of a pale fleshy-buff ground colour, 

 which gradually passes into a warm reddish buff on the larger end, 

 where there are spots and blotches of a slightly darker hue, 

 intermingled with underlying markings of faint purpli-sh-buff, the 

 surface of the shell being smooth and slightly glossy. Length, 0.86 

 X 0.61 inch. This egg resembles some of the delicately-coloured 

 varieties of those of Ptilotis auricomis. 



Figures of all the above eggs are included in the plates of the 

 second edition of the Australian Museuni " Descriptive Catalogue 

 of the Nests and Eggs of Australian Birds," now in the press.
