320 PEOCEEDINGS OP THE GEOLOGICAL SOCIETY. [May 7, 



been a thick fleshy frond, bnt the specimens are insufficient to show 

 its habit of growth. Its nearest allies seem to be C. Villiersi^ 

 Sternberg {Neuropteris Villiersi, Brongn.), and Cyclojoteris hetero- 

 phylla, Goeppert ; but it differs from both. 



44. Ctcloptekts Beownii, sp. nov. PI. XII. fig. 9. 



Pinnules large, cuneate, with distant, once-forlced nerves, and waved 

 margins. 



This is a mere fragment, but indicates a very distinct plant from 

 any known to me elsewhere. It was collected at Perry by Prof. C. 

 H. Hitchcock, and is named in honour of Mr. Brown, of Perry, one 

 of the earliest explorers of the beds at that place. 



45. Cyclopteeis i]S"Ceeta, sp. nov. PL XYI. fig. 44. 



Stipes Jialf an inch in diameter, giving off branches at acute angles, 

 on which are home, helow, branching [and recurved remains of fertile 

 pinnules and, above, traces of terminal obovate pinnules. 



I describe this plant rather as an indication of a species than as 

 one actually known. The parts remaining are similar in arrange- 

 ment to those of Gyclopteris Acadica of the Lower Coal-measures of 

 Nova Scotia, and prove the existence of a somewhat similar species 

 during the era of the Hamilton group in Kew York, from which this 

 specimen is derived. 



46. Keueopteeis seeeitlata, sp. nov. PI. XY. fig. 35 a, h. 

 Bipinnate. Bachis thin and slender. Pinnce alternate, sparsely placed, 



and of few pinnules. Pinnules obovate, narrowed at base, sessile, 

 delicately but sharply serrate, especially at the apex. Terminal 

 leaflet rounded and lobed, scarcely serrulate. Midrib visible nearly 

 to the apex. Pinnules about two lines in length. 



Prom the St. John shales, where it seems to be rare. It is a 

 delicate little species, quite distinct, iii so far as I am aware, from 

 any heretofore described. 



47. Keueopteeis polymoepha, sp. nov. PI. XV. fig. 36 a, h, c. 



Pinnate or bipinnate. Pachis or secondary rachis irregularly striate. 

 Pinnules varying from round to oblong, unequally cordate at base, 

 varying from obtuse to acute. Terminal leaflet ovate, acute, angu- 

 lated or lobed. Midrib delicate, evanescent. Nervures slightly 

 arcuate, at acute angles with the midrib. 



This Fern is very abundant in the shales near Carlton, at St. John. 

 At first sight it appears to constitute several species, but careful 

 comparison of numerous specimens shows that all the various forms 

 figured may occur on the same frond. In its variety of forms it 

 resembles N. heterophylla, Brongn., or N. hirsuta, Lesquereux ; but it 

 differs from the former in its dehcate midrib and acutely angled 

 nervures, and from the latter in its smooth surface. 



48. Sphenopteeis Hceh-inghatjsi, Brongniart. 



One of the Perns from the shales near St. John appears to be
