80. Sphenoptbris rbcurva, Dn.— J. G. S., XIX, PI. XIII, Figs. 7, 

 8, — U.D., Perry, Maine. 



" Leaflets small, cuneate, terminating the divisions of a dichotomous 

 winged petiole." 



81. Sphenoptbris splendens, S.N.— (PI. XVI, fig. 186.) 



Tnpinnate ; plnnoe oblong, broader at base, loith flexuom petiole, bearing 

 six to ten rounded, lobed, confluent pinnules, each with few veins 

 branching abruptly. 



I am sorry to add another to the many species of Sphenopteris ; but the 

 above will not accord with any known to me. Its nearest ally is perhaps 

 8. fragilis, Brong., but it is much more densely and closely constructed 

 than that species. Its petioles and nerves seem to have been woody, and 

 the frond thick, and in consequence it shines forth in all the metallic 

 brilliancy of a dense graphitic film, from which circumstance I have taken 

 its name. 



Genus Hymbnophtllites. — Goept. 



82. Hymbnophyllites cortilobus, Dn,— (PI. XVI, Figs. 178, 179.) 

 —J. G. S., XVIII, PI. XV, Fig. 39.— M.D., St. John, New 

 Brunswick. 



" Bipinnate. Rachis slender, dichotomous, with divisions margined. Leaflets 

 deeply cut into subequal obtuse lobes, each one-nerved, and about 

 one-twentieth of an inch wide in ordinary specimens." 



Some specimens of this species appear to show an inflection of the 

 extremity of the pinnules, as if from fructification. 



83. Hymbnophyllites sub-furcatus, Dn.— (PI. XVI, Fig. 180.)— 

 Acadian Geology, p. 652, Fig. 192, &c.— M. D., St. John, New 

 Brunswick. 



" Similar in general form to Sphenopteris (H.) fursatus, Brong., but 

 with broader and acute divisions of the pinnae." 



84. Hymenopyllites Gersdorpii, Goeppert. — (PI. XVI, Fig. 182.) 

 — M. D., St. John, New Brunswick. 



Quite similar to Goeppert's figures. 



86. Hymbnophyllites obtusilobus, Goeppert. — (PI. XVI, Fig. 183.) 

 — M.D., St. John, New Brunswick. 



Found with the preceding, which it closely resembles, except in its 

 greater size.
