T REFACE, 
The late Professor Lanrient Guillaume De Koniuck’s classical work — 
Reclierclies sur les fossiles paleozoiques de la Noiivelle-Galles du Sud 
(Australie) — was published in the years 1876-1877 as part of the Memoires 
de la Societe roijale des Sciences de Liege, 2iid ser., Vol. II. This work 
was the description of numerous fossils collected and submitted to De Koninck 
hy the Pev. W. B. Clarke, M.A., P.Pi-.S. The types and named sj)ecimens 
Avere, after description, deposited in the latter gentleman’s collection, and 
on his death were purchased hy the Government of Ncav South Wales. 
Unfortunately, a few years afteinvards, this invaluable collection was 
destroyed hy fire on the burning of the Garden Palace, on September 22nd, 
1882. 
Parts I and II containing the descriptions of the Upper Silurian and 
Devonian fossils have been prepared for this edition by me. Part III, 
relating to the Carboniferous and Permo-Carboniferous fossils, was translated 
some years ago by Professor T. W. EdgeAA^orth David, B.A., P.G.S., and 
Mrs. David. 
The translation has been made as literal as possible, and the Author’s 
meaning has been closely adhered to. The tables of synonyms preceding 
the descriptions of previously known forms have been left as De Koninck 
published them ; such corrections or additions as have been thought essential 
are inserted as foot-notes in square brackets, and are initialled.
