OF NEW SOUTH WALES. 211 



" Ibis," Proceedings and Transactions of Zool. Soc, London, 

 and the Transactions of the Linnean Soc, London. Our copies of 

 the last three works however, I regret to say, are more or less 

 imperfect, and in that of the "Ibis" large gaps appear, so that 

 any corrections which my scientific friends may point out, will be 

 very thankfully received. 



With respect to the localities and distribution of the species, 

 notwithstanding Mr. Gould's great work, they have been com- 

 piled chiefly from my own notes and those of Mr. George 

 Masters, Curator of the Macleayan Museum, who has collected 

 largely in nearly all parts of Australia. Mr. F. G. Waterhouse, 

 Curator of the Adelaide Museum, has also kindly furnished me 

 with data on Central Australian birds, and several rare species 

 for examination. I may mention that out of the 744 species 

 enumerated in this list, 725 have been personally examined by 

 me ; of the remaining 19, five at least are varieties only, or 

 doubtful species, the rest, chiefly Procellaridce, I have had no 

 opportunity of examining ; their names, and the localities given, 

 are for the most part taken from Mr. Gould's Handbook. 



Since the foregoing list has been printed off, Mr. Masters 

 informs me that he has received from Port Darwin, a fine new 

 species of Cracticus, allied to 0. quoyi, but having a larger and 

 stronger bill, the description of this species, which has been 

 named after its discoverer Cracticus spaldivgi, will be published 

 in the next number of the Society's Proceedings. This brings 

 the number of recognised Australian species to 745. 



Finding it necessary to separate the yellow- breasted Pachy- 

 cephalia of Western Australia from those of New South Wales, I 

 embrace the present opportunity of stating my reasons for so 

 doing, and of pointing out the differences between these two 

 species. 



While lately examining a large series of Pachycephalce from 

 various parts of Australia, my attention was drawn by Mr. Masters
