TIIK FLORA OP THE COAL FORMATION. 481 



doubled ill at both edges, and is abruptly broken off. It seems to be 

 a new species ; but of what affinities, it is impossible to decide. Bay 

 de Chaleur (Sir W. E. Logan). 



2. N. flabdlata^ L. and H. M. C, Sydney (R. Brown). 



Cyclopteris, Brongn. 



(including Cyclopteris proi)er, and subgenera Aneimites, Daws., and 



Neitropteris, Brongn. in part). 



1. Cijclopfcris heterophylla^ Goeppert. M. C. and U. C, Joggins 

 (J. W. D.). 



2. C. [Aneimites) Acadica, Dawson, Quart. Journ. Geol. Soc, vol. 

 xvii. p. 5 (Fig. 75). Stipe large, striate, branching dichotomously 

 several times. Pinnae with several broadly obovate pinnules grouped 

 at the end of a slender petiolule, and with dichotomous radiating veins. 

 Fertile pinnoi with recurved petiolules, and borne on the divisions of 

 the main petiole near their origin. This plant might be placed in the 

 genus Adiantites, Brongn., but for the fructification, which allies it 

 with such ferns as Aneimia. It has a very large frond, the main 

 petiole being sometimes three inches in diameter, and two feet long 

 before branching. Flattened petioles have sometimes been mistaken 

 for Cordaites and Schizopteris. It is a characteristic plant of the 

 Lower Coal measures. L. C, Horton (C. F. Ilartt); Norton Creek, 

 N.B. (G. F. Matthew). 



3. C. oblonffifoUa, Goeppert. A little larger and coarser than 

 Goeppert's figure. U. C, Fictou (.1. W. D.). 



4. C. [Neuropteris) obliqua., Brongn. M. C, Sydney (R. Brown) ; 

 Grand Lake (C. F, Hartt). 



5. C. {? Neuropteris) ingens^ L. and H. M. C, Sydney (R. Brown) ; 

 Grand Lake and Springhill (C. F. Hartt). 



6. C. oUata, L. and II. M. C, Sydney (R. Brown). 



7. C.fimhriata, Lesquereux. M. C, Sydney (R. Brown). 



8. C. hispida, spec. nov. Pinnate ; pinnules obovate, diminish- 

 ing in size towards the point, decurrent on the petiole ; veins slender, 

 distant, forking several times ; under surface covered with stiff hairs. 

 M. C, Sydney (R. Brown). 



9. C. aniiqua, spec. nov. L. C, (?) Herbert River (,T. AV. D). 

 Tripinnate ; petioles slender ; pinnules oblong, obtuse, decurrent 

 on the petiole, not contiguous. Terminal pinnules much elongated ; 

 venation simple, divergent. This jilunt ai)proachcs more nearly to 

 the peculiar species of Oijclopteris t'uund in the Devonian, than any 

 of the others I have seen in the Carboniferous.
