KEPORT — 1884. 



uppermost Jurassic age far to the -westward, a little east of the moutlia of tie 

 river Indus. The similarity of the plant-remains in the two series lias caused 

 them to be classed tofrether, but it is not certain that they are really of coiitum- 

 poraneons origin. 



The following is a list of the Jubalpur plants : — ^ 



Coxifer-T;. — Palinsi/a, 2 ; Arauraritcs, 1 ; Ecldnofitrohiii, 2; BrachyplnjUum, ]; 



Ta.vitci, 1 ; ' Gtnyko, 1 ; I'hwniropKh, 1 ; Czehamnrshia, ] . 

 Cycadkace.e. — I\eroi>hj/llni)i, I ; rtiloj7/iijllnm,2 ; Po(lozamites,P> ; OtozamiteUji; 



WillktmKonia, 1 ; Vjicddites, 1. 

 FiLicEs. — Sphenoptms, 1 ; Bic/isonid, 1 ; Alethopteri^, 3 ; Miicrotccniopicrh, 1 ; 



Glussopteris, 1; Saijenopteris, I. 



Of these thirty species nine are regarded either as identical witli forms found in 

 the Middle Jurassic (Lower Oolitic) of England or as closely allied. 

 The Cutch plants belong to the following genera : — '^ 



C0N1FERJ5. — Palissya, 3 sp.; Puchyphyllum, 1; Echinoftrohus, 1; Aruu- 



caritcs, 1. 

 Crc.iDEACE.T5. — IHil()j>/iyUu)ii, 3 ; Otozamites, '6 \ Cycadltes,\ •, IVilliamsonw,}; 



Oycadolcju's, 1. 

 I'lLlCES. — Oleandridium, 1; Tfrniopterifi, 1; Alethnpteris, 1; Pccopfvm, ]; 



Pachypteris, 2 ; Acdiioptcris, ] . 



Of the twenty-two species enumerated four are identified with .specific fornn 

 found in the Middle Jurassic of Yorkshire, and seven others are closely allied 

 The Cutch and Ja^alpur beds, in short, are intimately related with European fossil 

 iloras. 



One interesting fact should be mentioned. The Cutch flora occurs in the upper 

 part of the Umia beds, the lower beds of Avhich contain cephalopoda of Piutlaiidiaii 

 and Tithonian forms. In a lower subdivision of the Cutch Jurassic roclvs, the 

 Katrol group, shown by numerous Ammonites to be allied to Kimmeridge and upper 

 O.\.ford beds of AVesterii Eurojie, four species of plauts have been found, of wliitli 

 three are met witli in the Umia beds, and the fourth, an English oohtic form, iu the 

 Jabalpur series. This evidence seems in favour of the view that the flora under- 

 went change more slowly than the marine fauna. 



It will be as well, before leaving the subject of the Gondwana groups, to show 

 in a tabular form the geological age assigned to the flora and fauna of eadi 

 separately, on the evidence atforded by comparison with the plants and animals 

 known from European formations.
