392 KNOWLTON: FIGS FROM WYOMING AND MONTANA 
No Ficus fruits have been before described from the Laramie or 
any of the related formations. 
It is of course impossible to connect these fruits with leaves 
of Ficus in the same beds, though it is possible they may have 
belonged to a certain large-leaved species present. 
OcCURRENCE: Lance formation (‘‘Ceratops beds’’), Lance 
Creek, Converse County, Wyoming. Collected by J. B. Hatcher, 
June 1881. Types in United States National Museum. Also 
found in the Lance formation (‘‘Hell Creek beds’’) on Hell 
Creek, Montana, by Barnum Brown of the American Museum 
of Natural History, in which institution these specimens now are. 
Ficus Russelli sp. nov. 
Fruits similar to the preceding but in general much larger, 
’ with coarser, more prominent ribs. 
_ It is perhaps doubtful if this should be considered as specifically 
distinct from the last. In manner of preservation and general 
appearance they are identical, but the largest example from Con- 
verse County scarcely reaches the size of the smallest specimen 
under consideration, Thus one of the smallest examples is about 
3 cm. long and has a diameter of fully 2.5 cm., while the largest 
somewhat exceed a length of 4 cm. and a diameter of 3 cm. The 
pit or depression at the apex showing the point of entrance into 
the interior is perhaps more prominent and seemingly larger, but 
it must be confessed the differences are not great. 
The material upon which this species is based, numbering 
between thirty and fifty very perfectly preserved specimens, was 
collected by Prof. I. C. Russell near Forsyth, Montana. The 
matrix is a shattered, calcareous sandstone and the fruits are 
imbedded at irregular distances and in all positions, and yet none 
is distorted in the least. Associated with the fruits are numerous 
fragmentary shells belonging to five or six species; and a few 
fragments of leaves were found in the same beds but unfortunately 
they are not determinable.
