ment of fig. 3, which shows the same kind of nervation, but more distinct 

 than in figs. 1 and 2. In fig. 1, however, the impression of the right side of 

 the specimen shows the rays flat, or nearly so, like those of fig. 3, with distinct 

 though very thin veinlets. Fragments of this kind are very common at 

 Golden, at the same locality where I could compare them in place; but 

 I was unable to find any larger part of the fronds, which, considering the 

 petiole, do not seem to have been of great size. The species is compara- 

 ble to F. Lamanonis, Brgt, as described in Sap., fit., i, p. 70, pi. iv, fig. 5, and 

 especially to F. {Sahal) Andegaviensis, Schp., Pal. Vc'g(it., ii, p. 490, a species 

 not yet figured, but which, according to the observation of Saporta, is 

 closely related to that of Golden, and is found in the Upper Eocene of La 

 Sarthe, France. F. Lamanonis is from the same formation, the upper part 

 of the Gypses of Aix. The position of the rays at the top of the rachis, not 

 passing lower and not narrowed to an acute base, seems to indicate the refer- 

 ence of this species to Flabellaria rather than to Sabal. 



Habitat. — Golden, especially common at the locality called Table Mount- 

 ain, south of the School of Mines; Black Buttes, where I found the specimen

Frond large; racbis dilated under the rays, taper-pointed and acuminate; rays very numerous; 

 primary veins thick, nearly at <qual distance; intermediate veins distinct, few, one lo four. 



This species is represented by fronds of large size, of which, however, 

 we have not seen any fragments better preserved than that figured here. The 

 rachis is broad, flattened and split at the top by compression, as seen on the 

 right side of a casually superposed fragment of a ray, gradually narrowed, 

 acuminate, fourteen centimeters long from the dilated part under the rays, 

 and here six centimeters broad, regularly striate, as seen only near the 

 borders, under the lowest rays, where the epidermis is not destroyed, 

 merely convex downward, at the part where it is broken. The very 

 numerous rays, ninety to one hundred, attached all along the point of the 

 rachis, are deeply carinato-costate, slowly enlarging upward, distinctly nerved, 

 at least where the epidermis is preserved ; nerves thick with few intermediate 

 distinct veinlets. In the specimens figured here, where we have only the
