FROM THE IIUTTOX COLLECTION. 16 



Andrae, is very distinct from the preceding species, Sphen. trifo- 

 liolata, or any of its numerous variations from age or other 

 causes. Besides being much smaller the pinnules are more 

 rounded and entire, and the terminations of the pinnae are often 

 not broken up into pinnules but form a large undivided leaf. 

 This appears to be only a fragment of the frond of a large fern, 

 and it is on a kind of shale which I cannot identify with any 

 belonging to this Coal-field. 



Tribe. NEUROPTERIDE^l. 



ODONTOPTERIS, Brongniart. 



? Odontopteris Schlotheimii, Brongniart. 



Type — Odontopteris Schlotheimii, Brongt. Hist. Yeg. 



Foss., pi. 78, f. 5. 



Filiates osmundceformis, Schloth., Flor. d. Yorw., t. 5, f. 5, 6. 



115. — Fern leaves. 



On this slab are a few elongated-oval leaves which may turn 

 out to be generically distinct from any form yet described 

 from this Coal-field, and having much the appearance of an 

 Odontopteris or the pinnules of Otopteris ? dubia. Foss. Flora, 

 pi. 150. 

 Loc. — Shale abo^ve the Bensham Seam, Jarrow. (H. C. 659). 



Remarks. — The pinnules on ISTo. 115 bear a strong resemblance 

 to some of the pinnules of Schlotheim's Filicites osmundceformis, 

 Flora d. Yorwelt, t. 3, f. 5, 6, especially to the elongated pin- 

 nules on fig. 6, but this last figure is rejected by Brongniart and 

 not referred to his Odontopteris Schlotheimii. It is not easy to 

 understand why Brongniart rejects fig. 6, for surely the pin- 

 nules marked a on both of Schlotheim's figures ars alike. Then 

 again these pinnules have a strong resemblance to Grutbier's 

 figures, Yers. Zwick. Schwarzk, pi. 9, f. 10, 11, but the imper- 

 fect specimens and the not satisfactory figures of Gutbier, do 

 not enable me to identify it with any of them. For the present 

 it seems preferable to refer these pinnules to Brongniart's species 

 based on all the figures given by Schlotheiro, as quoted above.
