whorl, from a decidedly rounded termination to a very acute one. 

 The plant appears to have been of a much more firm and rigid con- 

 sistence than A. foliosa. 



41. ASTEROPHYLLITES . 



A small species, somewhat resembling A. galioides (Foss. Fl. t. 25. 

 f. 2), but the leaves are much broader, very obtuse, and almost wedge- 

 shaped. 



42. Bechera grandis, var. {B. tenuis, C. B. in Silliman's Journal.) 



So very similar to the B. grandis from Colebrook Dale (Foss. Fl. 

 vol. iii. t. 173), that I can find no difference between them except in 

 size, and I think they can hardly be considered as distinct species. 

 The specimens from Cape Breton agree perfectly with those collected 

 by Mr. Lyell in Alabama. 



43. PiNNULARiA CAPiLLACEA. {Liiidl. ^ Hutt. Foss. Fl. vol. ii. 



t. 111.) 



Apparently identical with Lindley and Hutton's plant. 



(Vegetable remains, which appear to have been the roots of aquatic 

 plants, are frequent in the coal-shale in this collection ; some of them 

 resembling that which is figured in the ' Fossil Flora,' t. 1 10 ; others 

 larger and thicker, but evidently of a soft and succulent nature.) 



I find in Mr. Lyell' s collection the following species from the same 

 coal-field, in addition to those sent me by Mr. Brown : — 



44. Pecopteris Serlit, Brongn. 



Not distinguishable from small specimens of the Somersetshire 

 plant. 



4.5. Cyclopteris. 



Different from the Cyclopteris previously mentioned (No. 8 of this 

 list) ; perhaps C. dilatata, but the specimen is not perfect enough to 

 be determined with certainty. 



46. SiGiLLARiA Organum. (Lindl. ^ Hutt. Foss. Fl. vol.i. t. 70.) 



47. Sigillaria Saullii. {Brongn. Veg. Foss. vol.i. 456. t. 151.) 



Agrees sufiiciently well with Brongniart's description and figure, 

 but it seems to have been part of an aged stem, and the markings are 

 rather obscure. The species was first found at Oldham, Lancashire. 



48. Asterophyllites tuberculata? 



According to Mr. Binney*, this is different from A. tuberculata, 

 but identical with an undescribed species found near Manchester. 



What at first appears most striking in the fossil vegetation of the 

 Cape Breton coal-field is (as Mr. Lyell has already remarked) its 

 very close agreement with that of the same period in Europe. Of 

 about 37 species or varieties contained in the foregoing list^ which
