Length, 15 mm. Width, 10 mm. 



Horizon and Locality. — Lowter Cordaite Shales at Fern Ledges, 

 Lancaster, N.B. 



This form is proportionately narrower than S. latum and has closer 

 veins. 



Sphenophyllum gemma n. sp. Plate VI, Pig. 7. 



A whorl of about sixteen strap-shaped leaves, flattened vertically. 

 Each leaf contains a main nerve and two short lateral nerves; each leaf 

 terminates in two strong points. The leaf is about 5 mm. long and 1^/4 

 to 11/^ mm. wide, and there are about three mucros to the leaf. The 

 lateral margins of the leaves are not distinct, owing to the condition o:^ 

 preservation, and if each prominent vein-bearing lobe is to be considered 

 a leaf there were 15 to 16 leaves in the whorl. 



Length of the whorl, 11 mm. Width, 9 mm. 



Horizon and Locality. — Bed 1 of Hartt's Section (Dadoxylon Sand- 

 stone), Pern Ledges, Lancaster, N.B. Collected by W. J. Wilson and 

 in the Cabinet of the Geological Survey of Canada. 



This species has some points of resemblance to S. hifurcatum, Lî.^ 

 in the division of the leaves; these however do not end in long sharp 

 points but short and blunt ones ; in this it is more like some of the leaves 

 of S. Schlotheimii, Bgt. figured by Lesquereux.^ 



Sphenophyllum innocens n. sp. Plate VI, Fig. 8. 



Stem and fructification unknown. 



The node has a whorl of about eight or nine cuneate leaves; each 

 leaf has one long central depression, and two short ones extending in 

 from the outer end of the leaf, less than one-half of the length of the 

 leaf; no mucronate points are preserved, but the anterior margin is un- 

 dulated, and no veins are distinctly shown. 



The substance of the lea:£ appears to have been very thin as it has 

 left only a thin film on the shale, but the surface of the leaf is strongly 

 undulate, rising between the nerves in long, narrow, rounded ridges. 



Length of the leaf, 15 mm. Width, 8 mm. The whorl of leaves is 

 about 30 mm. long and 27 mm. wide. 



Horizon and Locality. — Lower Cordaite shale, Fern Ledges, Lan- 

 caster, N.B. Collected by W. J. Wilson and in the cabinet of the Geolo- 

 gical Society of Canada. 



Better examples may show that this species is allied to S. erosum, 

 L. and H., but the leaf as preserved shows no lobes.
