THE BIRDS OF AUSTRALIA, 
specimens in a like bad state of preservation from Lake Frome, in the interior 
of South Australia. I suggest the name of A. fiaviventris as being descriptive 
of the yellow abdomen, and the vernacular name of Plain-fronted Tit as 
being descriptive of the absence of the freckled markings on the fore-head that 
are so characteristic of this genus.” 
The specimen was given to me by Mr. Ashby for the purpose of describing 
and figuring in this work, and it was obviously distinct, though being a formalin 
preserved specimen was in very poor condition. I renamed it Geobasileus 
ashbyi , as an Acanthiza jlavigaster had been previously proposed, and it had 
been a custom of purists to claim these names as equivalent. Later I proposed 
for it the new genus name Keartlandia, leaving for the present opportunity 
the task of characterising and distinguishing the genus. It was with great 
surprise when I undertook this that I found the generic characters to agree 
with Aurepthianura, and upon comparison it became obvious that the supposed 
“ Acanthiza ” was the female of Aurepthianura aurifrons and, moreover, from 
the type locality of Gould’s species. Accepting blame for my blunder I must 
make excuse that I did not anticipate such an error on Ashby’s part. I have 
now figured and described Ashby’s type. 
As it is a rare interior dwelling bird no subspecies were named until I 
prepared my “ Reference List ” in 1912, when I arranged them so, and the 
only emendation since has been the usage of the genus Aurepthianura .
