Rays narrow, convex or obtusely carinate, narrowly doubly striate, diverging at 

 acute angles from the racbis. 



The specimen, entirely represented by the figure, is too small and too 

 fragmentary for positive identification. As far as seen by comparison, 

 however, the reference seems authorized. The rays are connate in the 

 lower part and disjointed above; the striee are formed by alternate depres- 

 sions and ridges as seen upon the enlarged fragment, fig. b, c, with 3 to 4 

 intermediate veinlets. The fragment also resembles Flabellaria Zinkeni, 

 but the primary nerves are more numerous and less marked in this last 

 species and the intermediate veinlets more numerous.

This fine leaf has evidently the same character as those figured in 

 pi. XXV, figs. 11-14, and represents the same species. In vol. vii of the 

 "U. S. Geol. Rep.," p. 134, I alluded to this leaf, referring it to M. latiloba 

 of Heer, var. acutiloha, Lesqx. This variety now goes to 21. diversifolia, 

 described, I. c, in some of its multiple forms.
