     Absolutely - thanks to all who clarified this. Doesn't make them any 
     easier to tell apart!

In the beginning there was Zoothera dauma occuring from  Asia India, China, 
Pilippines, Indonesia, PNG, Aus. and straggling to Europe. (there were also 
a few other species of Zoothera). Many subspecies were recognised. 
Vernacular names included White's Thrush (Europe) Scaly Thrush (Asia) and 
Australian Ground Thrush. Julian Ford in 1983 reviewed the Australasian 
subspecies and split-off two species: (1) the "Basian Thrush" Z. lunulata 
lunalata and Z. l. cuneata;  and (2) the "Russet-tailed Thrush" Z. heinei 
and Z. h. papuensis. Acceptance of this was slow but Sibley & Monroe (1990) 
accepted it (with the change that they placed papuensis with lunulata) 
followed by Christidis & Boles (1994). Zoothera dauma is currently 
recognised as a species breeding mainly in n. Asia (W. Siberia to Urals and 
Japan, Himalayas and s-c. China) and wintering in S.E. Asia. That's as much 
as I know, but I expect that more tinkering has or will occur with sclay 
thrush taxonomy overseas.
The RAOU Records Appraisal Committee (now Birds Australia Records 
Committee) received a submission of Z. dauma from Booby Is. Torres Strait 
(21/12/77) (case 38), but it was not accepted. Back before the beginning in 
the old checklists the Australian Ground-Thrush went by the scientific name 
of Oreocincla lunulata and was treated as a species in its own right. The 
First Slater Field Guide Vol 2 Passerines listed Australian Gorund-Thrush 
Z. dauma and Atherton Ground-Thrush Z. cuneata. 
I hope this is all as clear as the back-end of a thrush in the forest on a 
wet morning 10 minutes before sunrise?
