PALAEONTOLOGY OF NEW-YOKJC. 
404. 9. BUTHOTREPHIS GRACILIS ? 
Pl. V (bis). Fig. 1. 
This is a specimen in sandstone, where the material of the fossil has been removed, leaving 
an impression in the stone. 
405. 10. BUTHOTREPHIS PALMATA (n.sp.), 
Pl. VI. Fig. 1.—Pl. VII. Fig. 1 a, b. 
Stipe strong, thick, rounded, branching in a more or less palmate or digitate form ; branches 
round, thick and strong, terminating abruptly. 
This plant presents a strong rounded stem, sometimes with several branches, often with two 
or three only ; the branches are usually little divergent. Sometimes the branching takes place 
altogether from near one point, while in others there is a succession of bifurcations at different 
distances from the base. Detached branches are frequently found, having the character of simple 
round stems, which are not especially interesting. 
This species is less abundant than several of the others, and but few specimens have been 
seen as perfect as those figured. 
In its thick and strong stems and branches, this fossil more resembles a zoophyte than a true 
marine plant; and it is not improbable that this, among other species, will prove such, be¬ 
longing to the Alcyonidia or to the Sponges. The almost entire absence of calcareous matter 
has precluded the existence of the calcareous skeletons of the ordinary corals in all the deposits 
of this group in its eastern extension. 
Plate VI, 
Fig. 1. A specimen showing numerous branches diverging from nearly the same point, 
Plate VII. 
Fig. 1 a. A specimen where the branches separate at different distances from the base. 
Fig. 1 b. Another specimen, apparently of the same species, showing successive branches from 
a single stem. This is a very unusual form, though I am not able to find characters 
to separate it from the preceding one. 
The rugose surface represented in the engraving is due to weathering, and is 
not a character of the species. (State Collection.) 
406. 11. BUTHOTREPHIS IMPUDICA (n. sp.). 
Pl. VI. Fig. 2. 
Stems smooth, strong, round, of nearly uniform size, terminated above by a kind of spongi¬ 
form stigma or swelling, which expands at its base beyond the diameter of the stem. 
This is a rare species, not more than three or four individuals having been seen. It is associated 
with the preceding species in the shaly sandstones. The specimens are probably the branches of 
a ramose stem. 
Position and locality. Blackstone’s and Wadsworth’s quarries, New-Hartford, below the 
lower ore bed. (State Collection.)
