1 6 Lane and Saunders: Oolitic Plant Re7nains. 



March 1909, with a query appended. As the type-specimen 

 is deposited in the Newcastle-on-Tyne Museum, Mr. Elgee, of 

 Middlesborough, very kindly took the plant for comparison 

 with the Newcastle specimen. On the opinion of the curators, 

 ' there is absolutely no doubt about the plant being C. haihurn- 

 ensis.' 



Cladophlebis lobifolia. 



The narrow bases of the pinnules, and the spreading habit 

 of the frond are plainly seen. The plant is unfortunately 

 embedded in sandstone, and the venation is poor. We hope 

 some day to obtain a better specimen. 



TODITES WILLIAMSONIA. 



A good specimen. The bipinnate frond, stout rachis, 

 slightly falcate pinnae, and the venation are well preserved. 

 This is an addition to the Marske collection. 



CONIOPTERIS HYMENOPHYLLIOIDES. 



A splendid -specimen, the tripinnate, linear, acuminate 

 pinnae, and other characters are clearly seen. 



Taxites zamioides. 



We obtained two good specimens of this plant. The slender 

 axis, the narrow linear leaves, with the single median vein are 

 so well preserved as to make it easy of identification. 



Up to the date of writing, thirty-eight species have been 

 found, and their identification may be regarded with a degree 

 of certainty. The discovery of Wealden plants in the Inferior 

 Oolite of Marske, considering the vast intervals of time which 

 must have elapsed between these periods, opens up a suggestive 

 field of research, and adds to our knowledge of Jurassic flora. 

 The commoner species which are found in abundance, are 

 Williamsonia pecten, W. gigas, Teniopteris vittata, T. major, 

 Baieva gracilis, B. lindleyana and Nilssonia mediana. 



The seventeen species found by the late Rev. J. Hawell in 

 this quarry, has now been increased to thirty-eight. 



Again we express our indebtedness to Mr. Elgee, curator of 

 Middlesborough Museum, for kindly assistance in determinating 

 many specimens, and especially to Professors Nathorst and 

 Seward, for their valuable help. 



The type specimen of Pseudo)nelania vittata Phillips, from the Corn- 

 brash of Scarborough (figured in ' Geology of Yorkshire,' 1829, pi. VI'I., 

 fig. 15), has been found in a reserve cabinet in the Manchester Museum. —
