shorter and more obtuse than in Whittleseya elegans, while the form of 

 the leaf is not elongate as in W. undulata, whose teeth are also short." 



The species above described is associated on the same shale fragment 

 with Alethopteris and a fragment of Neuropteris (labelled Neuropteris 

 Selwyni) apparently indistinguishable from a plant from the upper 

 Pottsville of the Appalachian province described in manuscript by the 

 writer as a variety of Neuropteris Schlehani, Stur. 



Locality " Fern ledges," Lancaster formation,^ near St. John, New 

 Brunswick. 



"The type of the species is with No. 73 (391) in the collections of 

 the Geological Department of McGill University, Montreal." 



Besides this species two other forms have been found in the ma- 

 terial collected by Mr. W. J. Wilson at the Fern Ledges now in the 

 collections of the Geological Sui'vey of Canada. These are described 

 below. 



Whittleseya concinna n. sp. Plate VI, Fig. 9. 



Stem and fructification unknown. 



Leaf quite small, longer than broad, bluntly rounded at the base, 

 arcuately truncate at the top, sides nearly parallel, but diverging some- 

 what toward the front, front edge, or tip, with an entire margin. The 

 substance of the leaf is thick and the surface smooth, but it is traversed 

 by numerous, parallel, longitudinal striae of which there are about 5 in a 

 millimetre. Nerves or narrow ribs can be faintly discerned in the sub- 

 stance of the leaf, these are about one millimetre apart, and in the lower 

 third of the leaf are occasionally seen to divide dichotomously. No 

 petiole is present, and there are no distinct continuous costae on the sur- 

 face of the leaf.

 Geological Survey of Canada, Ottawa. 



This is clearly distinct from the preceding species both in the form 

 and markings, but in these respects it comes near W. desiderata D. 

 White, from the shales of Harrington river, N. Scotia; it is, however, 

 considerably larger than that species, and does not have the fine teeth 

 at the end of the leaf, which that species is said to possess. 



Whittleseya concinna var. lata n. v. Plate VI, Fig. 10. 



Stem and fruit unknown. 



Leaf very broad in proportion to its height, narrowed to a broad 

 base without any trace of a pedicle; the front edge is arcuate, with a
