ture so closely agrees. It seems probable that where the cone axis 
of Geinitzia was much elongated the peltate expansions of the cone 
scales are hexagonal by contact with numerous other scales and that 
on the other hand, where the cone axis was short, in analogy with the 
living Sequoia, that the scales may have been generally four-sided. 
Among American figures which indicate elongated cones with six- 
sided scales may be cited the following,*? referred to Sequoia gracil- 
lima (Lesq.) Newb., while the shorter type, with four-sided scales, 
may be clearly seen in the cone attached to a leafy branch, figured 
by Fontaine* and referred to Sequoia ambigua Heer. 
We have thought it advisable to distinguish between those Geinit- 
2445 which have the long cone and hexagonal scales and those which 
have the short cone with tetragonal scales, by making the two new 
genera, Eugeinitzia and Pseudogeinitzia. In that case our first 
described scale would come under Eugeinitzia and the second under 
Pseudogeinitzia. It.may, of course, turn out that the length of the 
cone is not a determining factor in the number of angles of the cone 
scale, in which case the shape of the scales may alone be taken into 
consideration in bestowing the names suggested.

These little cone scales, which we have thus far only found 
detached, are very abundant in the lignitic debris of the Androvette 
pit. Their araucarineous affinities have been determined beyond
