264 THE POTOMAC OR YOUNGER MESOZOIC FLORA. 



Only one specimen was found. The cone, whose form is pretty well 

 preserved, is in shape and in the character of the scales a good deal like 

 Sequoia. It resembles more than any other cone that of Araucaria Cretacea 

 Brongniart, as given by Schimper,^ but it is much smaller. 



Aeaucaeites Aquiensis, sp. nov. 



Plate CXXXIII, Figs. 8-12. 



Scales of the cones varying considerably in size and shape, attaining 

 the maximum dimensions in length of 5""" and in width across the top of 

 3'''", with the minimum of 3.5*"" by l.S"™; scales probably closely appressed 

 and imbricated, wedge-shaped, and narrowed at base into a sort of foot- 

 stalk, thickened at the summit, and rounded on the upper margin, with a 

 depressed transverse furrow, very deciduous, and always found scattered 

 singly and sparingly in the clay. 



Locality: Bank near Brooke. 



These scales are not uncommon. No cone was found from which they 

 could come. In their shape and deciduous character they resemble some 

 of the forms of Ahies. The scales are like those of Dammara also. Near 

 their summits they all show on one face a distinct curving imprint, as if 

 made by the pressure of the terminal edges of the overlapping next lower 

 scales. I have taken its specific name from Aquia Creek, near which 

 the locality yielding them occurs. 



CARPOLITHUS St. 



Under the head of CarpoUthus I place a number of nut-like seed of 

 conifers which have not been found in connection with leafy branches, 

 and whose proper place can not be made out with any certainty. No 

 doubt some of them belong to some of the conifers described with other 

 names, the characters being taken from leafy branches. These fruits form 

 an important element in the Potomac flora, and they are the most abun- 

 dant gymnospermous fruits found.
