supposed by him to be of Eajmahal age, but lie missed the rich 

 fossiliferous beds of Yemavaram and Budivada. These last- 

 named formations, both of marine origin, are considerably 

 unlike each other, the Budivadas being a calcareous, gritty 

 sandstone fully charged with oysters and other shells, and 

 a very few, but typical, Eajmahal plants. The Yemavaram 

 beds on the contrary being fine hard shales often semi-porce- 

 lanic and full of exquisitely preserved vegetable remains, 

 accompanied by a few marine shells, fish remains and other 

 fossils, the most interesting of the latter being a" beautifully 

 fossilized, but unfortunately somewhat imperfect, impression 

 of a crustacean of the genus Eryon. 30 



The most noteworthy fact with regard to the fossil plants 

 was the predominance of Dictyozamites falcatus — one of the 

 most typical Eajmahal forms known. Pterophyllum, another 

 very characteristic Eajmahal form, is represented by more 

 than one species. In point of beauty of preservation the 

 Yemavaram fossils are almost unequalled. A description 

 of this flora, which is by far the richest of any of the plant 

 formations fringing the east coast, has been given by Dr. 

 Feistmantel in the Palmontologia Indica, vol. i, part iv, of the 

 Flora of the Grondwana system, " outliers of the Madras coast." 

 In the absence of that very interesting volume which the 

 writer has not by him in camp, only the best known and com- 

 monest species will be enumerated : — 



Alethopteris Indica. 

 Tseniopteris spathulata. 

 Pterophyllum Footeanum, Feist. 

 Pterophyllum 2 other sp. 

 Ptilophyllum acutifolium. 



Do. cutchense. 

 Otozamites sp. 



Dictyozamites falcatus. 

 Palissya sp. 

 Eelmiostrobus sp. 

 Arancarites sp. 

 Cunninghamites sp. 

 Taxites sp. 



30 This crustacean was figured and described by Dr. Feistmantel who con- 

 siders it very closely allied to, if not identical with, Eryon Barroviensis of 

 the English Lias, in the Kecords (vol. x, 1877).
