2. " On an extinct Chelonian Reptile (Notochelys costata, Owen) 

 from Australia." By Prof. Owen, C.B., F.R.S., F.G.S. 



The fossil reptilian remains hitherto transmitted to the author from 

 Australia have been limited to parts of the skeleton of Megalania 

 prisca, Owen. The present specimen, sent last year by Professor 

 Liversidge, is the first fossil Chelonian. The specimen was found 

 in a formation at Blinder's River, Queensland, of which the nature 

 and age are not stated. It is, however, petrified. The fossil con- 

 sists of the anterior portion of the carapace and of the plastron, 

 brought into unnaturally close contact by posthumous pressure. A 

 minute description of the several parts was given, from which the 

 author concluded that though the chai'acters of the carapace might 

 be interpreted as identifying the Chelonian with a true turtle 

 (Chelone), those of the plastron show the well-marked distinctions 

 of Trionyx and Chelys. On the whole, however, the modifications, 

 especially of the carapace, show a nearer affinity to the marine 

 turtles (Chelone) than the known Chelydrians exhibit, and indicate 

 a more generalized type. 



3. " On the Upper Beds of the Fifeshire Coal-Measures. " By the 

 late E. W. Binney, Esq., F.R.S., F.G.S., and James W. Kirkby, Esq. 



These beds are best exposed in Fife, between the mouth of the 

 Leven and East Wemyss. The Coal-field of the latter district is the 

 most northerly piece of true Coal-measures in Britain ; they dip 

 10° E., or even less. The highest member (which may possibly be 

 even later than the Carboniferous Period) is an unfossiliferous 

 purplish sandstone, full 200 feet thick ; next comes soft red marl, 

 12 feet, followed by sands, 290 feet, marls, clays, etc., 100 feet, and 

 sandstones, clays, etc., with thin coal and limestones, about 80 feet. 

 Other sections were also described. No unconformity has been 

 noticed in Fifeshire between these and the underlying measures. 

 The argillaceous limestones and their coals are fossiliferous ; there 

 are a few fish and Crustacea, and many plants, with some curious 

 markings, which may be rootlets or perhaps algee. The last occur 

 only in a limited part of the rock, not with other plants, and are 

 very delicate and membranous. The affinities of these were fully 

 discussed, the author inclining to the view that they are algas.
