PLATE IX. Fig. 2. 
Large surfaces covered with what appear to be fragments of stems of some marine plant, are 
common in the same position with the species last described. They appear like fragments of 
plants that have been broken by the action of winds and waves, and then floated in an even 
layer upon the surface of the water, and thus deposited. These fragments are sometimes very 
uniform in size, but generally they are composed of those of various size and length. Slabs of 
the stone, often two or three feet in diameter, are covered as uniformly as the fragment in the 
engraving. 
Position and locality. Gaylord and Norton’s quarry near New-Hartford, Oneida county. 
(State Collection.) 
ROOTS OF DIFFERENT SPECIES OF MARINE PLANTS, &c. 
Pl. X. Fig. 4, 5, 6 & 8. 
Fig. 4 is a rootlike expansion similar to figs. 9 a, b, & 10, which are referred to Buthotrephis 
palmata. This specimen, however, differs in some particulars, and it was found in a situation 
where B. palmata has not been seen. 
Position and locality. Ruddock’s quarry near Clinton village. 
Fig. 5 presents two specimens, evidently roots of some species not yet distinguished. 
Fig. 8 has the root with a small portion of the stem attached, but in such a condition as to 
present no reliable characters. 
Locality same as the last. 
Fig. 6. Two fragments upon the surface of a stone, which appear like stems of some marine 
plant with abrupt swellings at the extremities, although they have a nearer resemblance to bones 
with large apophyses at their extremities. These, however, have nothing bone-like in their 
structure, and are probably concretionary, either originally, or of matter around some organic 
body. 
Position and locality. Blackstone’s quarry. 
Pl. VIII. Figs. 4 a, b, & 5. 
These specimens are fragments evidently of the roots of some marine plants, but their con¬ 
nection with stems has not been traced. 
Position and locality. Blackstone’s quarry.
