CANADIAN FOSSILS. 



61. C. (Archaiopteria) Eogersi, Dn.— (PI. XV, Fig. 171.)— J. G. S., 

 XIX, 468 ; PI. XVII, Figs. 17, 18. PI. XIX, Fig. 27.— U. D. 

 Perry, Maine. 



** Habit of growth resembling that of Oyclopterii Jacksoni, but the pin- 

 nules are more elongated and almost cnneate in form, also lesi 

 densely placed, and with veins more nearly parallel. Stipe stout, 

 woody, furrowed longitudinally, and marked with strong transverse 

 bars or punctures." 



A specimen, obscure in details, but which must belong to this or the 

 previous species, occurs in Prof. Hall's collection, from Montrose, Pa., and 

 presents the curious peculiarity of showing no less than nine petioles pro- 

 ceeding from a common origin, as if the plant had either been a low- 

 growing simply pinnate fern, with its fronds in dense clusters, or had 

 grown on a common stipe in a densely palmate manner. Perhaps the 

 former is the more probable supposition. 



62. 0. (Aneimites; valida, Dawson.— (PI. XVI, Fig. 190.)— J.G.S. 

 XVII, 819, PI. XVI, Fig. 52.— M. D., St. John. 



" Tripiunate ; primary divisions of the rachis stout and wrinkled. Pinnaa 

 regularly alternate. Lower pinnules nearly as broad as long, deeply and 

 obtusely lobed, narrow and decurrent at the base ; regularly diminishing 

 in size and breadth toward the point, and the last pinnules narrowly obo- 

 vate and confluent with the terminal pinnule. Nerves dehcate, several 

 times dichotomous." 



63. C. (Aneimites) obtdsa, Lesquereux. — PI. XVI, Fig. 188.) — 

 Rogers's Report on Pennsylvania, p. 854 ; PI. 1, Fig. 11. J. G. S., 



;;# XVIII, 319, PI. XV, Fig. 33.— M. D., St. John, N. Brunswick. 



64. C. (Aneimites) Bockshii, Goeppert. (Lesqx.)— (PI. XVI, Fig. 



187)— Report Pennsylvania, p. 854, PI. IH.— M. D., St. John, New 

 Brunswick. M. D., Pennsylvania. 



This may be a variety of 0. obtusa, but Lesquereux thinks it distinct, 

 and fronds perfectly similar to those which he baa figured occur at St. 

 John. 



65. Cycloptbris BaowNn, Dn.— (PI. XV, Fig. 172.)— J. G. S., 

 ■ XVII, 32 ; PI. XII, Fig. 9. lb. XIX, 463 ; PI. XVII, Fig. 6. 



— U. D., Perry, Maine. Pennsylvania? 



*' Pinnules large, cuneate, with distant, once-forked nerves, and waved 

 margins."
