The variety mentioned is the first note of F. inelanogaster, commonly so 
called. No specimens are available from this locality at present. When Kuhl 
worked through the Banksian drawings he accepted this identification, and 
I feel there is much more likelihood that Rochefort’s drawing was made from 
this species than from P. marina (see ante, p. 23). The long forked tail of 
Rochefort’s drawing, however, prohibits the acceptance of Linne’s name for 
this bird. 
Though Bonaparte’s identification of P. grallaria Vieillot with T. leucogaster 
Gould has been continuously accepted since his time, I can trace no writer 
who has examined Vieillot’s type. Examination of a series of so-called grallaria 
convinced me that there was much confusion, and as it is well known that many 
of Vieillot’s so-called New Holland species never came from that locality, I 
could not be satisfied until I had seen Vieillot’s bird. Mr. A. F. Basset Hull 
forwarded me for examination a specimen picked up dead on Lord Howe Island, 
and this further convinced me of the futility of working without examination of 
the type of Vieillot’s P. grallaria. I therefore applied to my friend M. Menegaux, 
Curator of Birds at the Paris Museum, for the loan of the specimen} and, with 
his usual unfailing courtesy and interest in the cause of science, my request 
was acceded to. 
I am now able to give details of the many forms called P. grallaria, and 
also able to show that two distinct species, each having their own well-marked 
subspecies, have been confused under that name. As all writers have hitherto
