nate position that they are likely to he altogether lost sight of. 
The work is illustrated by a few woodcuts in the text and fifty 
plates ; some of these are from photographs of dry or spirit speci- 
mens, others, representing the minute structures &c., have been 
drawn by the author. These latter in many instances are some- 
what crude in appearance ; but their lack of artistic merit may 
perhaps he compensated by greater accuracy of detail. Dr. von 
Lendenfeld may he congratulated on his good fortune in obtaining 
the assistance of the Royal Society to bring out such an important 
and, judging from the price set upon it, expensive publication. 
MISCELLANEOUS. 
On the Discovery of a Jurassic Fish-Fauna in the HawTcesbury Beds 
of Neiv South Wales . By A. Smith Woodward *. 
A large collection of fossil fishes from the Hawkesbury-Wiana- 
matta series of Talbralgar, New South Wales, has been forwarded 
to the author for examination by Messrs. C. S. Wilkinson and R. 
Etheridge, Jun., of the Geological Survey of New South Wales. 
The final results will appear in a forthcoming memoir to be published 
by that Survey ; but the investigation has already proceeded so far 
as to justify the announcement of the discovery of a typically Jurassic 
fish-fauna in Australia. Eine examples of the Palaeoniscid genus 
Coccolepis occur, and this has previously been met with only in the 
Lower Lias of Dorsetshire, the Purbeck Beds of Wiltshire, and the 
Lithographic Stone of Bavaria. A new fish allied to Semionotus , 
but with thinner, much imbricating scales, is also conspicuous ; and 
another new T form, allied to the Dapedioids, is remarkable from the 
presence of typical rhombic ganoid scales in the front half of the 
trunk and deeply overlapping cycloid scales over the whole of the 
caudal region. A Leptolejois-like fish, with a persistent notochord, 
seems to represent a third unknown generic type. Of Leptolepis 
itself there are many hundreds of individuals in a fine state of 
preservation. The fishes occur in a hard, ferruginous, fissile matrix 
associated with well-preserved remains of plants. 
The Fossil Fishes of the HawTcesbury Series at Gosford , New South 
Wales . By A. Smith Woodward f. 
Some years ago an early Mesozoic fish-fauna was discovered in a 
bed of dark grey shale in the Hawkesbury Eormation at Gosford, 
New South Wales, and the collection was forwarded to the author 
for determination. The present memoir comprises the results of
