but probably in less abundance, was the species described 
as Picea harrimani , which is quite closely allied to the 
P. sitchensis now living in the region. There are branches 
which undoubtedly belong to a spruce, and a single seed 
which in all probability also belonged to a Picea . Scat¬ 
tered over many pieces of matrix are numerous short, 
thick coniferous leaves which may well have belonged to 
this species of Picea . The genus Pinus is more or less 
uncertain, but is apparently represented by several de¬ 
tached leaves 5 cm. or more in length, and scales that ap¬ 
pear to represent a broken pine cone. Sequoia evidently 
did not have a very prominent place in the flora, as it is 
represented only by a single cone that is referred to <5. 
heerii of Lesquereux, and a much broken cone that may 
or may not be of the same species. The few branchlets 
referred to Tatxodium tinajorum are hardly to be distin¬ 
guished from T. distichum miocerium and may be only 
more robust examples of the latter. 
The next most conspicuous family, in point of species 
as well as individuals, is the Betulacese. Betula itself is 
represented by a small but unmistakable fragment of the 
bark which shows the well-known lenticels. The most 
abundant dicotyledon in the collection is Cojylus mac - 
quarrii , which is represented by leaves and fragments. 
Of the two species of Corylus described as new, C . har¬ 
rimani must have been a magnificent tree, with leaves 20 
cm. in length and 17 cm. in width. Judging simply from 
the present collection, this was not a very abundant 
species. The somewhat anomalous leaves described as 
CorylusP palachei may or may not belong to this genus. 
The remaining members of the Betulaceae are two forms 
of Alnus , one of which (A. corylifolia) is represented by 
a considerable number of small, sharply serrate leaves. 
The Juglandaceae are represented by a single species 
each of Juglans and Hicoria , the latter being a truly
