This little fragment of a conifer is referred provisionally to 

 the above species, partly on account of its close similarity and 

 partly because the species associated with it seem to warrant 

 such reference. It is one of the commonest species in the Am- 

 boy clays of New Jersey at several localities, and has also been 

 found on Staten Island and Martha's Vineyard. 



Locality : Near Black Rock Point, Block Island.

This is another well defined and typical Amboy clay species 

 of wide geographical distribution, which, when found with 

 Moriconia would, without any further evidence, be sufficient to 

 determine the horizon in which is occurs. 



Found also on Staten Island and Martha's Vineyard. 



Locahty : Near Black Rock Point, Block Island.

The fragment figured is apparently the upper part of an 

 ament similar, if not identical, with those described by Heer un- 

 der the above name. Inasmuch, however, as he also describes 

 and figures aments which can hardly be distinguished from 

 these, under the name of Myrica longa (Fl. Foss. Arct., Vol. vi.
