(loublcrl in at both edges, and is abruptly broken off. It seema to be 

 a new species ; but of \\ bat affinities, it lb impossible to decide. Bay 

 dc Chalcur (Sir \V. E. Logan). 

 2. N.jlabellata, L. and II. M. C, Sydney K. Brown). 



Cycloptkuis, Brongn. 



(including Cyclapteris proper, and subgenera Aneimites, Daws., and 



Neuropteris, Brongn. in part). 



1. Cyclnptcris hctcrophylla, Goeppcrt. M. C. and U. C, Joggins 

 (J. W. D.). 



2. C. {Anehaites) Acadica, Dawson, Quart. Journ. (jlcol. 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 pinnae with recurved petiolules, and borne on the divisions of 

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

 genus Adiantiles, 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 Cordaitcs and Schizopteris. It is a characteristic plant of the 

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

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



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

 Goeppert's figure. U. C, Pictou (J. W. D.). 



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

 Brand Lake (C. F. llartt). 



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

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



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



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



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

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

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

 M. C, Sydney (R. Brown). 



9. C. antiqua, spec. nov. L. C, (V) Herbert River (J. W. D . 

 Tripinnate; petioles slender; pinnules oblong, obtuse, decurrent 

 on the petiole, not contiguous. Terminal pinnules much elon^ateil ; 

 venation simple, divergent. This plant approaches more nearly to 

 the peculiar species of Cyclopt<ris found in the Devonian, than any 

 of the others I have seen in the Carboniferous.
