Nos. 6 & 7.] THE AUSTRAL AVIAN RECORD 131 



submitted to him, which as he has shown elsewhere should 

 date from the " Synopsis " instead of from certain 

 numbers of the Proceedings of the Zoological Society, 

 which were not issued until long after the dates they 

 bear. Mr. Mathews also added a number of species 

 described from material not in the collection purchased 

 by Dr. Wilson. This enlarged list has again been revised 

 by both of us, and the Catalogue of Birds in the British 

 Museum has been consulted for data on types preserved 

 in that institution. 



In the case of each species, one specimen has been 

 selected as the type and so marked, and usually this 

 selection has been easily made, as the individual bird 

 described by Gould was readily identifiable by locality, 

 sex, measurements, etc. In other cases where no indi- 

 vidual bird was mentioned in the original description, 

 the selection has been arbitrary, and is final. 



While most of Gould's Australian types are in the 

 collection of the Philadelphia Academy, it should be 

 borne in mind that some species were described from 

 material that was never in his possession ; a few other 

 types were never sent over, better specimens, apparently, 

 having been substituted ; while types of species described 

 after the date of the Wilson purchase in 1847, are usually 

 to be found in the British Museum, which secured Gould's 

 later Australian material. 



In the following list the species have been arranged 

 by Gregory M. Mathews in the order of his Reference 

 List, with the numbers of the list preceding each name. 



The first specimen number of the type is that of the 

 Ornithological Catalogue of the Philadelphia Academy, 

 while that in parentheses refers to the Verreaux Cata- 

 logue. Where the type-locality given in the original 

 description differs in any way from that on the specimen, 

 it is given in parentheses after the reference. 



[In some cases the locality is given as " New South 

 Wales = Queensland." The latter state was part of 

 New South Wales up to 1859. Victoria was also part 

 of New South Wales up to 1850.]
