BTATHOESTIA. 147 



V. 2376. PL IX. Figs. 2 and 20. 



The specimen suggests either a delicate and graceful type of 

 frond or large pinna, or a young condition of a more robust form. 

 No venation is seen, except a slight trace of a midrib in some of 

 the pinnules, e g. Fig. 2a. Some of the smaller specimens referred 

 to Cladophlelis Dunkeri (Schenk) have a certain resemblance to 

 the upper pinnae of this species, but the likeness is probably 

 only superficial. The single pinna at * in Fig. 2, PI. IX. agrees 

 very closely with the pinnaB of PI. VII. Fig. 5. Ecclesbourne.

V. 2809. PI. VII. Fig. 5. 



This specimen, 4 cm. in length, differs from V. 2376 (PL IX. 



Fig. 2) chiefly in the closer arrangement and stiff er habit of the 

 pinna3, and in the smaller size of the pinnules. The lowest pinna 

 on the right-hand side of Fig. 5 agrees with those on the left side 

 of the rachis and close to the apex of PL IX. Fig. 2. The matrix 

 is different in the two figured specimens, and this fact alone is 

 often sufficient to account for apparent differences in form. 



Several of the pinnules have lobed margins like those of PL IX. 

 Fig. 20, and here and there a midrib is indicated. 



I was at first inclined to refer this fragment to Goppert's genus 

 Gleichenites, 1 which includes several species from Mesozoic plant- 

 bearing beds ; but the small and incomplete nature of the material 

 would hardly justify the choice of such a generic term in the 

 absence of any definite evidence of a Gleichenia habit or fructi- 

 fication.
