and referred by him to Chara Meriani, A. Br., agrees fairly 
closely with our Wealden form. 
Another species, Chara Stantoni,! recently described by Knowl- 
ton from the Upper Cretaceous Bear-River formation of North 
America, agrees in the large number of almost horizontal ridges 
_ with Chara Knowltoni, but differs in shape. 
Among English Tertiary species there is a distinct similarity 
to a specimen of Chara medicaginula, figured by Lyell,’ showing 
the ‘‘nut”’ enclosed in the “integument.” The inner part 
(‘‘nut’’) has a close resemblance to the present species. 
The common recent species Chara fetida, A. Br., possesses 
oogonia not far removed in appearance from the Wealden type, 
but, as Lyell points out in reference to Tertiary species, the fossil 
oogonia are more globular than those of living British species.

Some of the oogonia are fairly well preserved and show the 
characteristic markings clearly. Near Hastings.

V. 2282. A cluster of oogonia closely crowded together, with 
odd ones scattered about. The spherical form well shown, but 
markings indistinct. Ecclesbourne. Rufford Coll.

with the surface markings fairly clear. Ecclesbourne.
