The present Part is the first of a Monograph of the Carhoniferons and 
Permo-Carhoniferons Invertehrata of Isew South MMles, contained in the 
Mining and Geological ]\.Tuseum of the Department of Mines, Sydney. It 
includes the whole of the Coclenterata at present existing therein, hut a few 
additional specimens have been obtained from outside sources, and will he 
suitably acknowledged later on. It is intended to issue the succeeding Parts 
as time and the state of tlie Collection will permit. 
In the preparation of the descriptions I have frequently taken 
advantage of the valuable local knowledge and assistance of my colleagues, 
Mr. C. S. Wilkinson, L.S., &c., the Geological Surveyor-in- Charge, and Mr. 
T. "W. Edgeworth David, P.A., Geological Surveyor. 
To Mr. John Waterhouse, M.A., Inspector of Schools, I am under 
great obligations for the kind manner in whicli he has always striven to 
advance the objects of this work, by unreservedly placing his Collection at 
my disj)osal, and information at all times kindly supplied. 
The Corals herein described have been obtained under the direction of 
Mr. C. S. 'VPilkinson, partly by Mr. Charles Cullen, Collector to the Geological 
Survey, and partly under the supervision of Mr. T. AA. E. David, whose 
Geological Survey of the Maitland District embraces some of the particular 
coral-bearing beds described in this Alemoir ; but thanks are also due to the 
Pev. AV. H. Yarrington, M.A., Dr. Alorson, Mr. S. Dodds, and Mr. D. A. 
Porter, for sjiecimens given or lent; whilst the section-cutting has been 
satisfactorily performed by Mr. Charles Miirton, of the Geological Branch. 
I have also derived great assistance from a collection of Tasmanian Stenopor<v, 
partly collected by Mr. AY. Anderson, Geological Surveyor, and partly supplied 
by my friend Air. B. AI. Johnson, Government Statist of Tasmania. To my 
colleague Air. G. II. Barrow, of the Australian Aluseum, I am greatly 
indebted for the patience and skill displayed in the preparation of the original 
drawings, from which the plates have been heliotyped at the Government 
Printing Office by Air. A. E. Dyer, under the direction of the Government 
Printer.
