do justice to this classification ; but the shell is recognized as 

 modifying and in various ways being modified by the soft parts of 

 the animal, and therefore as affording a safer basis for classification 

 than any single anatomical character. C. R.

THIS is an Explanation of Quarter-sheet 97 S.W. (50 New Series). 

 It contains accounts of the Lower and Upper Silurian Rocks of 

 Ingleton, Oummack and Horton-in-Ribblesdale ; of the Carboniferous 

 Limestone Series, Millstone Grit and Coal-measures; and of the 

 Glacial and Post-Glacial deposits. Some dykes of Mica-trap pene- 

 trate the Lower Silurian rocks near Ingleton, and these intrusive 

 rocks are described by Mr. F. Rutley.

IN this Memoir we have detailed descriptions of the strata, from 

 the Keuper Sandstones and Marls of the Isle of Axholme, 

 upwards to the Kimeridge Clay that underlies the Cretaceous 

 escarpment. The several divisions of the Neocomian formation and 

 of the Chalk are described, together with the Glacial and other 

 superficial deposits. The Red Chalk is included at the base of the 

 Upper Cretaceous. Long lists of fossils are given from the Jurassic 

 rocks, and these are in part based on the work done by the Rev. J. 

 E. Cross, of Appleby. The deposits of economic importance include 

 the Frodingham Ironstone in the Lower Lias, and the Claxby Iron- 

 stone in the Neocomian. The Lincolnshire Limestone at Kirton-in- 

 Lindsey yields a good hydraulic lime, which is sold as " Blue Lias 

 Lime." A number of well-sections and borings are recorded in an 

 Appendix. 



IV. — On the Discovery of a Jurassic Fish-Fauna in the Hawkes- 

 bury Beds of New South Wales. By A. Smith Woodward. 1 



A LARGE collection of fossil fishes from the Hawkesbury- 

 Wianamatta 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 pro- 

 ceeded so far as to justify the announcement of the discovery of a 

 typically Jurassic fish-fauna in Australia. Fine examples of the 

 Palasoniscid genus Coccolepis occur, and this has previously been met 

 with only in the Lower Lias of Dorsetshire, the Purbeck Beds of
