narrowed downward to an obi use point, surrounded by an inflated margin or 

 thick border, and marked in the central space by wrinkles diverging from a 

 small round point under the upper border. The width of these scales is about 

 4 millimeters each way, being, however, especially in the upper part of the 

 cone, a little more expanded on the sides and broader than long. 



The reference of this fine cone to the genus Sequoia is not positively as- 

 certained. By the position and the form of its scales, it resembles the cones 

 described in Sternb., Flora der Vorwelt, (vol. ii, p. 184, PI. xlix, Figs. 2 a and 3,) 

 under the name of Bergera minuta, a species which is represented by better 

 specimens under the name of Cunninghamites sternbergii by Ettinghausen, in 

 his Kride Flora Von Niedcrs., (p. 12, PI. i, Figs. 4-G.) The cones of this 

 species, however, are proportionally shorter and broader, more obtuse, some- 

 times nearly round, and the scales, more enlarged in the middle, do not ap- 

 pear marked by an inflated border. In my description, loc. cit., I compared 

 this cone to Araucarites Sternberg/, Gopp., as figured in Heer's Urvvelt der 

 Schweitz, p. 310. This species is a synonym of Stcinhauera minuta, Sternb. 

 {loc. cit , vol ii, p. 202, PL lvii, Figs. 7-15.) The relation, however, is dis- 

 proved by the same degree of difference as with the former species, the 

 scales being in Sternberg's species more enlarged on the sides, without a 

 border, and the cones still more obtuse and proportionally broader. No fos- 

 sil cone described as yet, to my knowledge at least, has such a tapering coni- 

 cal form as ours, except tbe Lipidanthinm microrhombcum, Schp., figured in 

 Schenk. Foss. Flora, d. Grenzsch, (PI. xxxii, Fig. 8,) which is considered as 

 the inflorescence of some Cycadese. 



Habitat. — Near Decatur, Nebraska, Hayden. 



Sequoia reictienbachi, Heer, PI. i, Fig. 10-10''. 



Cone small, oblong-oval ; receptacles oval-pointed at both ends ; foliaceous scales crumpled, deeply 

 imbedded in tlio stone, seeds small, oval-oblong. 



Sequoia reiciienbachi, Heer, Molet. Flor., p. 8, PI. i, Fig. 2-3. 



The cone is cut vertically, and its axis, like the receptacles of the seeds 

 and their follicles, is exposed to view. It is narrowly oval, narrowed to the 

 slender peduncle, a little more than 1£ centimeters long and 1 centimeter 

 wide. The receptacles are empty, but distinctly cut into the stone as in 

 Fig. 10 b somewhat enlarged ; the scales and follicles arc vertically and deeply 

 imbedded, and their shape undistinguishable The axis is marked with deep 

 perforations indicating the points of attachment of the receptacles.
