Zoothera aurea on p. 60 of Holandre, Annuaire de la Moselle (1825) - not on BHL, nor google books that I can find.
I don't find it either. But, if you need something, you can perhaps point to Fournel 1836 [
here], who quoted the 1825 description
verbatim.
(The actual ref to this work seems to be:
Holandre JJJ. 1825. Faune du département de la Moselle, et principalement des environs de Metz, ou tableau des animaux que l'on y rencontre naturellement, avec diverses indications sur leur rareté, sur les lieux et les époques de leur apparition. Partie ornithologique. Verronais, Metz, 48 pp.
E.g., see contemporaneous publication report [
here]. This was followed by a second part (next year, 1826), covering mammals, reptiles and fish; publication reported [
here].
Holandre also published a more extensive work a decade later:
Holandre JJJ. 1836. Faune du département de la Moselle. Animaux vertébrés. Mammifères, oiseaux, reptiles et poissons. Mme Thiel, Metz.

Turdus aureus is described there as well, with "Faune de la Moselle 1825." as the authority; the description is on p.60 (which -- by coincidence...? I'd really be curious to see the 1825 original, actually -- is the page number cited by Hartert for the 1825 OD).)
Beware that Hartert's 1910
BB discussion is outdated.
The date of the publication of Pallas'
Zoographia Rosso-Asiatica has been a matter of contention. Except for the plates, the first two volumes of the work (which include birds) were printed in 1811, just after Pallas' death; but Pallas apparently wanted his plates to be engraved by a particular German engraver and no-one else, and the Academy of St Petersburg tried to have this wish fulfilled. As a result, (very) few exemplars were distributed at this time; the bulk of the distribution occurred much later (and with many/most plates still lacking). During the whole 1811-1831 period, some zoologists were aware of the work and accepted the names that appear in it, others were not and named the species that Pallas had described anew. Thus a fair number of species have a name by Pallas, and another one by someone else, which precedence relative to the name proposed by Pallas depended on the exact date of publication that was accepted for the
Zoographia. To put an end to these debates, the publication date of the two first volumes was fixed as 1811 (and that of the third volume as 1814) in
Opinion 212 of the ICZN (issued in 1954 -- obviously Hartert in 1910 could not have known this): this is the date to be adopted for
Turdus varius Pallas, which makes it senior to
Turdus aureus Holandre 1825.
We did not revert to using
Turdus varius Pallas 1811, because this name is a junior primary homonym of
Turdus varius Vieillot 1803 [
OD], and therefore permanently invalid. (Some Russian authors did revert recently, though, and are now using
Zoothera varia.)
