Ann. Rep. pL II, p. 782. 

 The few fragmentary representatives of this species seem to differ slightly 

 from the normal type in that the pinnies are somewhat closer together. There 

 is a very close agreement in the shape of the pinnies and in the nervation 

 with the Pennsylvania form described by Lesquereux. 

 Localities: Bowling Green, and Roadman School. 



Genus Callipleridium Weiss 



Callipteridium sp. 



PI. Ill, fig. 5; pi. IV, figs. 2, 4. 



The plants shown in pi. Ill, fig. 5, and in pi. IV, figs. 2 and 4 are close to 

 a form described by Lesquereux in MMS. as C. Tracyanum.^* 

 Locality: Yoho School. 



Call ipleridium sp. 

 PL III, fig. 7. 



This species is closely related to Callipleridium cf. Tracyanum but has 

 more fleshy pinnules, a less prominent midrib and a greater number of 

 nerves. The material at hand is not sufficient for definite determination. 



Locality: Yoho School. 



Genus Odonlopteris Brongniart 



Odontopteris Newberri Lx. 



PI. I, fig. 8; PL II, fig. la. 



1878. Odontopteris neuropteroides Newberry, Geol. Surv. Ohio, Paleontology, 



Vol. I, p. 381, pi. 47, figs. 1-3. 

 1880. Odontopteris Newberryi Lesquereux, Coal Flora, Vol. I., p. 127. 



The plant shown in plate I, fig. 8, agrees closely in all essential charac- 

 teristics with the Ohio forms described by Newberry. The form shown in 

 pi. II, fig. la, is doubtfully referred to O. Newberryi. It may represent a 

 closely related species. 



Locality: Yoho School.
