referred to L. primigenia, and has much the same nervation. It appears 
to have been correctly determined. Of the two fragments from Point 
of Rocks, probably only one (the original of fig. 10) can be correctly 
referred to this species. With Ettingshausen, 1 I must regard fig. 9 
as more like L. ocotecefolia Ett., and quite unlike typical forms of L. 
primifjenia. 
Habitat. — Point of Rocks and Carbon, Wyoming. Golden, Colorado. 
Evanston, Wyoming. 
Laurtts pr^estans Lx. 
PI. XVI, fig. 2. 
Laurus prcestans Lx., Bull. U. S. Geol. and Geog. Surv. Terr., Vol. I, p. 368 (1875); 
Ann. Rept. U. S. Geol. and Geog. Surv. Terr., 1874, p. 305 (1875); ibid., 1870, p. 
510 (1878); Tert. FL. p. 215, PI. LXIII, fig. 7 (1878). 
The type specimen of this species is preserved in the United States 
National Museum (No. 311). It represents a large, finely preserved leaf 
that is broadly elliptical-lanceolate in shape, being narrowed in about the 
same degree upward to a sharp-pointed, slightly scythe-shaped apex, 
and downward to the prominent petiole. The midrib is very thick, and 
the strong, equidistant parallel secondaries emerge at an angle of 
about 40°. 
This leaf is very suggestive generically of Ficus, yet, as Lesquereux 
has pointed out, it is evidently quite closely connected with various 
Lauraceae, as Persea speciosa Heer, Laurus princeps Heer, Laurus 
Canariensis Web., etc. 
I have referred to this species the single small specimen obtained by 
Professor Ward at Point of Rocks, which, although fragmentary, seems 
to belong to it. 
Habitat. — Point of Rocks, Wyoming.

The discussion of much that relates to the early history of this species 
has been given under Ficus trinervis, page 42. It was there shown 
that two species appeared to have been confused under the name of 
C. affine, and an attempt was made to remove the forms showing so 
marked differences from the type. 
The original locality whence came what maybe called typical G. affine 
(Tert. PI., PI. XXXVII, figs. 1-4) is unknown, as is also the location of 
the type specimens. The Princeton Museum contains a slab bearing 
several finely preserved leaves, which has a label attached reading as 
follows : "La. South Park, Col." The matrix is a hard white sandstone 
unlike anything with which I am familiar from South Park, but quite
