91. Pbcoptbris obscura? Lesquereux.— J. G. S., XVIII., 822.— M.D., 

 St John, New Brunswick. 



92. Pecopteris (AspiDiTES ?) PREOiosA, Hartt. — (PL XVIII., Figs. 

 210, 211).— Acad. Geol. 353.— M.D., St. John, New Brunswick. 



" Pinnae a little larger than those of the last species, not serrated ; 

 placed nearly at right angles to the rachis, obtuse, narrow towards 

 the extremity, suddenly widened, or almost auriculate at the 

 lower side ; mid-rib extending to the apex ; nerves few, at a some- 

 what acute angle." 



Somewhat more complete specimens in Prof. Hartt's collections show a 

 little more of the habit of growth of this fern than was previously known- 

 Both the pinnae and the pinnules were placed nearly at right angles to the 

 petioles. 



98. P. (Cyathites ?) DENSiPOLiA, S. N.— (PL XVII, Figs. 195, 193.)- 

 M.D., St. John, N. B. 



Bi-pinnate, pinnules oblong, rounded at the ends, crowded together on a thick 

 striated petiole, Mid-rih somewhat decurrent on the petiole, at an angle 

 of about 45 ® . Veins few, forking once, oblique. Margins of the larger 

 pinnules somewhat undulate. 



This new species occurs in Prof. Hartt's collections from Carlton, near 

 St. John, N.B.

, Genus Trichomanites — Goept. 



94. Trichomanites filicola, Dn.— J. G. S., XIX, 464 ; PL XVII, 

 Figs. 12, 13.— U. D., Perry, Maine. 



Pinnules slender, attached to long petioles, and bifurcating into slender 'points, 



96. Trichomanites, sp. -J. G. S., XVIII, PL XVI, 50.— M. D., St. 

 John, New Brunswick. . , , „ ... 



Bifurcate pinnules, extremely minute, thread-like, four to seven in each pinna. 



Both of these species are founded on fragments which are of doubtful 

 character, and may prove to be merely skeletons of fronds.
