Sin, 
I HAVE tlie honor to snl)init the acconn)anyiny Memoir on tin* 
Invertebrate Fauna, of the Kawkeshurn-lFianamatta Series (beds abore the 
productive Coal-Measures) of Neu: South JVales, by Mr. Bo1)crt Etlioridg’o, 
Junior, Palaeontologist. 
The Wiaiiamatta, lla\vkesl)ury, and NarrahcAUi rocks constitute, as 
yon are aAvare, extensive* tormations in the eastern central portion of tins 
Colony, and are well represented in the district of Sydney. They may l)c 
regarded as the uppermost memhers of the great coal-hearing grou]) whicli 
ranges down to tlu* Lower Carboniferous. 
The elucidation, tln'i-efore, of the Pahcontology of this series is of 
much interest in the determination of this important geological horizon, 
which appears to he liomotaxial with the Ihaas of the Northern Hemisphere. 
This Memoir is the lirst of the PaUeontological series of the Geological 
Survey of New Sontli IVales. Tlie second, on The Tertiary Flora, of 
Australia, by Baron C. von Ettiugshansen, is now in the hands of the 
Government Printer, and will soon l)e issued. Almost ready for the press 
(the illustrations are already })rintcd) is the recently revised work of Dr. 
Ottokar Eeistmantel on the Geological and Falceontological llelations of the 
Coal and Plant-bearing beds of Pakeozoic and Mesozoic Age in Eastern 
Australia and Tasmania, with special reference to the Fossil Flora ; also a 
translation of the late Professor de Koninck’s Pecherches sur les Fossiles 
Paleozdiques de la Nouvelle-Galles du Sud.

ment, British Museum, has kindly undertaken! the description of our tine
