DESCRIPTIOX OF THE SrEGIES. 81 



away to form a sort of potiole, uttaclied only In' the lower portion of the 

 base; midnerves strono-; lateral nerves not seen. 



Locality: Fredericksburg; very rare. 



This seems to be a very distinct species, it belmius to the Jnrassic 

 tvpi! of Cli«li>i)/tU'l/(s. It is something like I'vco^deris W'illiuinvuiii, Brong., 

 but is a much smaller form. 



CLADor-nLEBis, species ? sp. nov. 



riate XXVI, Fig. 15. 



Pinnules subfalcate, thick and leathery, separate to the Ijase, attached 

 by the whole of the widened base; in shape ovate-acute; nerves not seen. 



Locality: Fredericksburg. 



The small specimen iigured was the only one found. It seems to be 

 a distinct species. 



Clauophlebis brevipennis, sp. nov, 



Plate XXXVI, Fig. 1. 



"Frond, ? ultimate piinue very short, subopposite, cut to varying depths 

 into rounded, oval, or elliptical pinnules and lobes; pinnules rounded at 

 base; nerves strong, rather distant, com[)Osed of a midnerve dissolved a 

 short distance above its base into branches, which are once or twice foi-ked, 

 and curve strongly outwards to meet the margin of the pinnules and 

 lobes ; leaf-substance thick. 



Locality: Fishing hut above Dutch Gap Canal; very rare. 



This plant is something like Cladophlcbis constricta ; the nerves, how- 

 ever, curve outward more strongly, and are more copiously branched, and 

 the ultimate pinna; are much shorter. It is also something like Dunker's 

 Pccopteris Miirclmoni, but the pinnules are rounded and narrowed at base, 

 and the nerves are more flabellate and s[)reading. 



PECOPTERIS, Brong. 



Fronds once or several times pinnate; pinnules mostly entire, 

 attached by the whole of the base, which is rarely narrowed ; midnerves 

 extending to the tips of the pinnules ; lateral nerves going off on each side
