gracillima which have become lignified instead of silici- 
fied, I found one nearly perfect cone, which was about 3 cm. 
in length by about 2 cm. in diameter, which agreed almost 
exactly with Heer’s figures of this species. 
This was unfortunately smashed in transit, so that I now 
have only the recollection of it, which is not apt to be con- 
sidered good evidence. However, my first thought on un- 
covering it was that it was a cone of S. Feichenbachi. The 
foliage of this species is rather common in the clays at this 
point and we would reasonably expect to find the cones; the 
former are very fragmentary. Poorly preserved branchlets of 
Cunninghamites squamosus can often be traced for several 
inches, but the Seguoza remains are usually not over an inch 
inlength. The leaves are less closely set than in C. sguamo- 
sus and longer, often 9 to 10 mm., much more slender and 
more spreading. 
The best known localities for this species are: 
True Laramie and Livingston Beds: Bozeman coal field, 
Montana. Montana Formation: Point of Rocks, Wyoming. 
Raritan: Woodridge, N. J. Matawan: Clifford, N.J. Belly 
River series: Belly River, Canada. Potomac Formation: 
Dutch Gap Canal and Fredericksburg, Va. Dakota Group: 
Ft. Harker, Kansas. Kootanie: Great Falls, Montana. 
Kome Beds: Pattorfik, Avkrusak, Angiarsut, Erkorfat, 
Kaersuarsuk. Atane Beds: Unter Atanekerdluk. Europe: 
Wernsdorf (Urgonian) Saxony (Cenomanian), Quedlinburg, 
Moletein (Senonian), Rainberg bei Salzburg, Brandenberg, 
Tyrol, southern France (Turonian), Clays at Aachen, Prussia, 
Quadersandstein at Hartz, Bohemia. Cretaceous: Totten- 
ville, Staten Island. Lower Cretaceous: Black Hills. 
While this species had a wide vertical and areal distribu- 
tion ranging from the Upper Jurassic through the Cretaceous, 
it is best developed in the Lower Cretaceous.
