The pre.sont Memoir on “ The Fossil Fishes of the Ilan kesbuiy Series at 
Gosford,” in this Colony, hy my former Colleague, Mr. Arthur Smith 
M'oochvarcl, F.G.S., F.Z.S., of the Department of Geology and PaRon- 
tology, Natural History Branch of the British Museum, forms No. d 
of the Palaeontological Series of the Survey Memoirs. 
It is satisfactory to find that the Triassic age, hitherto assigned to our 
ITawkeshury-’Wianamatta Series, gains further support from Mr. AVoodward’s 
study of the Gosford Fish. 
Mr. T. "W. Edgeworth David, B.A., F.G.S., Geological Surveyor, has 
supplied a Chajjter on the Stratigraphy of the hods as displayed at Gosford, 
and an Index to the Genera and Species, Contents, and List of Plates, &c., 
has been added hy myself. 
The Collection was made hy Mr. Charles Cullen, Collector to the 
Survey.
