We were fortunate in obtaining a large series of this material near 
Harpers, Wyoming, during the season of 1896, and after much study 
and comparison I am unable to separate it satisfactorily from Heer's 
Geinitzia formosa. There is great range in size of branches and 
branchlets, but in all particulars the specimens agree with Heer's 
figures. 
These specimens were referred to Sequoia Reichenbachi of Geinitz in 
the preliminary notice, and it is a matter of some difficulty always to 
separate them. In general, 8. Reichenbachi may be distinguished by 
more slender branchlets, the leaves of one kind being decurrent, rigid, 
strongly incurved, acuminate at apex, while Geinitzia formosa has 
thicker branchlets, with decurrent, arched, pointed, not very rigid 
leaves, and with smaller intermediate scale-like leaves. When the 
leaves have fallen the scars or bolsters are quite regularly quadrangu- 
lar. The cones, of course, differ considerably and are easily separated 
when sufficiently well preserved. 
The material referred to this species from the Amboy clays of New 
Jersey, by Dr. Newberry, while not extensive, is sufficient for positive 
identification. 
Habitat (in the United States.) — Amboy clays, New Jersey. Near 
Harper Station, on the Union Pacific Eailroad, Wyoming. 
Geinitzia longifolia Lx. sp. 
Sequoia longifolia Lx., Ann. Rept. U. S. Geol. and Geog. Snrv. Terr. 1874, p. 298 
(1876); Tert. FL, p. 79, PL VII, figs. 14, 14a; PL LXI, figs. 28, 29 (1878). 
The type specimens of this species are preserved in the United States 
National Museum (Nos. 61, 73, 74), as are also a number obtained by 
Professor Ward at Point of Rocks. The specimens were well described 
by Lesquereux, and have simply been transferred to the genus Geinitzia, 
with which they clearly have greater affinity than with Sequoia, as 
already pointed out by Schenk. 1 
Habitat. — Point of Rocks, Wyoming. Coalville, Utah. Marshall's 
mine, Boulder County, Colorado.
