ADDENDA TO VOL. I. 231 



figured as Protorrkipis CJioffati, Sap., p. 144, pis. xxii., xxvi., 

 and xxvii., there are some which suggest leaves very similar 

 to those described by Bartholin from Bornholm under the name 

 of Haiismannia Forchhammeri, Earth. 



Sphenopteris tenuijissa, Sap., p. 161, pi. xxviii. fig. 4. In all 

 probability this is identical with Ruffordia Gopperti (Duiik.). 

 Saporta himself noted the close agreement ; but he does not 

 accept my determination of the broad-leaved fronds figured in 

 Vol. I. PI. VI. as a variety of Bunker's species. 



Adiantum eximium, Sap., p. 164, pi. xxviii. fig. 18; pi. xxxi. 

 fig. 6. Probably identical with R. Gopperti var. latifolia. 



In speaking of Cycadites Saportee, sp. nov. (p. 30), I have 

 drawn attention to the very close similarity of the Portuguese 

 specimens named by Saporta Cycadites tenuisectus. The numerous 

 dicotyledonous leaves described by Saporta are of considerable 

 interest, but need not be dealt with here, as we have no trace 

 of angiospermous fossils in our Wealden strata, which occupy 

 a lower horizon than the beds from which Saporta' s specimens 

 .were obtained. 



In taking a review of the whole flora described in his monograph, 

 Saporta calls attention to the remarkable series of types which are 

 represented in the plant-bearing beds ranging from the Corallian 

 to the Cenornanian ; the series is practically continuous, and 

 without any distinct break or hiatus in the succession of genera 

 and species. The flora is compared with that of the Potomac beds 

 of America ; a close comparison of the two sets of plants : has 

 also been recently instituted by Prof. Lester Ward.

Yokoyama followed up his account of the Jurassic plants from 

 Kaga, Hida, and Echizen, by a memoir on the Mesozoic plants 

 from Kotzuke, Kii, Awa, and Tosa. 2 Nathorst 3 had previously 

 described several species from some of these localities, and con- 

 cluded that the plant-bearing strata should be classed as transition
