great work on that family. And had I been able to detect any 
monocotyledonous wood among the lignites of this deposit, I 
should be inclined to refer some of the fruits to that family. _ 
In fig. 10, the longitudinal ridges are more prominent than i 
those specimens hitherto described, and the fruit is acuminate at 
its apex. It a good deal resembles certain species of walnut, dis 
engaged from the epicarp. But the fossil fruit has no hard endo- 
carp. It does not in this respect resemble the Juglandites rostrata, 
of which I have a specimen from the brown coal of Germany. 
In fig. 11 the longitudinal ridges are very prominent, and 4 
little oblique to the axis. I think it distinct from the other spe 
cies that have been described. But as I have found only one o 
two specimens, I am not very confident.

Fig. 12 represents a very distinct species of a triquetrous form. 
Some of the specimens a good deal resemble the Brazil nut, 
(Bertholletia excelsa,) others have the form rather of a large 
beech nut, (Fagus ferruginea.) Fruit dehiscent at the ape% 
with two, and probably three valves. Outside rough and some 
what ridged lengthwise. I have but a few specimens, it beimg 
_ one of the rarest species, and have not been able to satisfy my- 
self as to its internal structure. 
Fig. 13 may be a smaller species of the 13. 2 age 
same genus, as it is somewhat three-sided. gar 
But it is more deeply striated, and the largest f} 
side, shown in the drawing, is nearly flat. A \Y 
very rare variety. cs 
_Fig. 14 exhibits an elongated fruit, slightly striated longit 
dinally, and having an epicarp of considerable thickness. A thi? 
endocarp is contained within ; but the seed has disappeared, @ 
frequently, as a consequence, the fruit is compressed, and appea$ 
as if two-lobed. This is not an uncommon species. _ I have pe 
haps a hundred specimens. ‘ , a
