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. Reichenbachi. The 

 foliage of this species is rather common in the clavs at this 

 point and we would reasonably expect to find the cones ; the 

 former are very fragmentary. Poorly preserved branchlets of 

 Cunninghamites squamostis can often be traced for several 

 inches, but the Sequoia remains are usually not over an inch 

 in length. The leaves are less closely set than in C. squamo- 

 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 :

 Kome Beds : Pattorfik, Avkrusak, Angiarsut, Erkorfat, 

 Kaersuarsuk. Atane Beds : Unter Atanekerdluk. Europe :

 Tyrol, southern France (Turonian), Clays at Aachen, Prussia,

 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.
