The work is illustrated by a few woodcuts in the text and fifty- 

 plates ; some of these are from photographs of dry or si)irit 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 be compensated by greater accuracy of detail. Dr. von 

 Lendenleld may be congratulated on his good fortune in obtaining 

 the assistance of the Koyal Society to bring out such an important 

 and, judging from the price set upon it, expensive publication.

On tJie Discovery of a Jurassic Fish-Fai(7ia in the Haivl-eshury Beds 

 of New 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, Jim,, 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. Fine examples of the Palsconiscid genus 

 Coccolqns 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 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 Leptolejns-like fish, with a persistent notochord, 

 seems to represent a third unknown generic type. Of Leftolepis 

 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 HawTceshury Series at Gosford, Neiu South 

 Wales. By A. Smith Woodward f. 



Some years ago an early Mesozoic fish-fiiuna was discovered in a 

 bed of dark grey shale in the Hawkesbury Formation at Gosford, 

 New South Wales, and the collection was forwarded to the author 

 for determination. The present memoir comprises the results of
