succeeded by an Oolitic limestone of considerable thickness containing 

 fossils of the Fullers' Earth type, and forming a passage between the 

 Inferior Oolite and the Fullers' Earth, which comes next in succession. 

 Above this are sandy limestones, passage-beds, with Amm. gracilis, 

 a form found in the Stonesfield ' Slate.' The Great Oolite consists 

 of white Oolitic limestones with a Pholadomija-hed below, and an 

 upper series of wedge-bedded Oolitic limestones containing lenticular 

 patches of clay and sand with a Bradford Clay fauna. The Forest 

 Marble, which is of great thickness and monotonous character, consists 

 chiefly of shales, with bands of sandy, shelly, and Oolitic limestones. 

 It is followed by the Cornbrash. The Oxford Clay with the usual 

 zones, and the Corallian clays and pisolite close the sections. Fossil 

 lists and palseontological notes on each subdivision are given. 



The next meeting of the Society will be held on Wednesday, 

 November 5th, 1902.

NOTE ON A NEAELT COMPLETE SPECIMEN OF ICHTHYOSAURUS 

 THYREOSPONBYLUS FEOM THE KIMEEIDGE CLAY OF SPEETON. 



Sib, — It will be well to put on record a recent find of this 

 inicommon species, especially as the remains now discovered are 

 more complete than any previously recorded, and largely increase 

 our knowledge of the osteology of this animal. "While examining 

 some recent exposures to the north of the Speeton " Middle CliflF," 

 Mr. C. G. Danford, of Eeighton, detected some vertebrate remains. 

 He was successful in the course of several days in excavating 

 53 vertebrae, a large number of ribs, the lower jaw, and portions 

 of paddles, all clearly belonging to one individual. Dr. Smith 

 Woodward has identified the remains as those of Ichthyosaurus 

 thyreospondylus, Owen, and associated fossils confirm the age to be 

 Kimeridgian. The vertebras of this species were figured by Phillips 

 in his "Geology of Oxford," 1871, and, so far as I can find, no other 

 portions of the skeleton were known until the discovery of the 

 present specimen. Yorkshire is also a new locality for the species. 



Mr. Danford has generously placed the specimen in the Hull 

 Municipal Museum. This Museum, which is now Corporation 

 property, has as a nucleus the collections of the old Literary and 

 Philosophical Society, and as at present an attempt is being made to 

 get together a typical local collection of fossils, the gitt of this 

 skeleton is a most opportune one. 



The only other important remains of sauria from the Kimeridj^e 

 Clay of Yorkshire were found in a brick-pit near South Cave many 

 years ago, and consist of two large paddle-bones, some vertebree, etc. 

 These also the Hull Museum has been fortunate enough to secure, 

 through the generosity of Mr. G. W. B. Macturk.
