dant fossil. Heer regards the Cape Boheman Jurassic as Middle Brown 
Jura (Bathonian) in age. ° 
Pl. LXIII, Fig. 4, gives one of the most complete forms, and Pl. 
LXIV, Fig. 1, represents a form with somewhat narrower leaflets. 
An imperfect specimen is seen at Fig. 4 of Pl. LXVI, and it seems 
probable that the parts of leaves represented by Figs. 8 and 4 of Pl. 
LXVII belong to this plant.

Two or three detached leaflets of a Podozamites of the type of P. 
lanceolatus were found at the locality ‘“‘In the bed of a ravine that 
leads from the Banner mine,” etc., which seem to differ at least vari- 
etally from the narrow P. lanceolatus, being broader and shorter. 
They agree well with the leaflets described by Heer’ from the Jura 
formation on the Upper Amur as a variety latifolius of P. lanceolatus.

Portions of a plant that appears to be a Baiera, near B. mobtifida 
Font., of the Older Mesozoic of Virginia, were found in two speci- 
mens; one, showing the basal part, given in Pl. LXV, Fig. 1, was 
obtained at the locality ‘‘In the bed of a ravine that leads from the 
Banner mine,” etc., and the other, showing lacinie, represented in 
Fig. 2, at the locality ‘‘ Bank of Feather River,” ete. The amount of 
material is too small to permit a positive determination of the plant. 
It is, however, a coarse, large form, that reminds one strongly of 
Baiera multifida Font.
