OSMUNDA Sp. ? 



Plate LXVII, Fig. 3. 



Description. — This specimen is one of the many masses of rootlets, at- 

 tached to rhizomes, which occur in abundance in a black clay at the base 

 of the bluff at Tally Point. Dr. L M. Underwood, of Columbia Uni- 

 versity, to whom they were submitted, decided unhesitatingly that they 

 were the rootlets and rhizomes of some fern, most probably an Osmunda. 

 It was found impossible to separate them from the matrix without break- 

 ing, either when wet or dry, hence they are shown in the figure exactly 

 as collected and subsequently preserved. 



Occurrence. — Talbot Formation. Tolly Point (Bay Eidge) Anne 

 Arundel County.
