perhaps the Lithostrontion of Par- 
kinson. Basaltic angular tubes con- 
camera ted, stellate inside, with pores 
outside uniting the tubes. Tribe ol 
Tubiporites, 1. L. alba . *Tubes 
unequal 5 or 6 angles, concamera- 
tions as long as broad, pores in a 
row. 2. L . basaltic a . Tubes une- 
qual, 4 to 6 angles, concamerations 
short, pores scattered. Both from 
limestone of River Ohio, silicified, 
beautiful and very rare. 
55. Tubiporites. S. G. Gonopora , 
Raf. Differs from Latepora, from 
want of pores. L T. amorpha . 
Mass amorphous, basaltic, tubes un- 
equal nearly smooth, concamera- 
tions short. Sandstone of Knob- 
hills. 
56. Fav^osites. Differ from last 
by simple tubes without concamera- 
tions. 1 . F. convexa , Raf. 1819. 
Mass rounded, conical depressed be- 
neath, convex above, tubes subequal 
pentagone, striated inside and out- 
side, mouth substellate. Sandstone 
of Knobhills, Silicified, fine, 3 inch- 
es and more. 
57. DIPLORITES, Raf. Tubes 
angular, with round mouths or end, 
subconcamerated, no pores. 1. 1). 
pulchra . Mass subamorphous, up- 
per surface undulate, mouths even 
unequal, large ones in rows sur- 
rounded by many small ones, not 
stellate cellular, tubes hardly stria- 
ted. Sandstone of Knobhills, sili- 
cified, fine, 4 inches long. 
58. Flustrites Rubra , Raf. Amor- 
phous, lobulate, elongate, flabellate 
and undate, surface red with regu- 
lar rows of raised cells, having ribs 
between the rows at the base. Beau- 
tiful specimen 4 inches long, from 
the Knobhills, silicified. 
59. DIPLEN1TES, Raf. 1819. 
Large cells and minute pores mixt 
together; thus uniting the charac- 
ters Cellepora and Millepora. 1. 2). 
lobulata. Irregular depressed, lob- 
ulate, both sides convex with irregu- 
lar and unequal cells, and several 
remote unequal pores. Sandstone 
of Knobhills. Several other species. 
60. GRIM ITES, Raf. Large flat 
cells or pits on the surface, not raised 
as in Cellepora. 1. O. cava. Elonga- 
ted irregular, with cavities inside, 
outside with many oblong unequal 
cells. Sandstone of Knobhills. 
61. Mitleporites Vervucosa> Raf. 
Compressed, subramose flexuose, 
covered all over with warts nearly 
smooth, and many minute pores be- 
tween them. Limestone of Blue 
licks in Kentucky, 2 to 6 inches. 
62. FISTULIPGRA, Raf. Dif- 
fer from Millepora by being tubu- 
lar. i. F. teres. Cylindrical, nearly 
simple, smooth, pores round, nearly 
equal. Limestone of Kentucky. 
63. TGRULIPGRA, Raf. Differ 
from Millepora by a moniliform 
shape and appearance of toeing free, 
not fixed. 1. T \ monilia. Free, 
elongate, curved, collar like or to- 
rulose, segments solid oblong une- 
qual, pores crowded and equal* 
nearly oval and in transverse rows. 
Sandstone of Knobhills. 
X ALCYONITES. 
This last and lowest tribe of fossil Animals 
is very prolific in the West. It is the link 
between Animals, Plants and Minerals: and 
it is as yet doubtful tb which series the Spon- 
ges, Septaria and Geodes belong. They re- 
quire a new study and revision. I shall give 
here many N. G. with a single sp. nr type 
except tie Cyclorites of the Supplement. 
64. BOLACTITES, Raf. disc. 1819. 
Outside globular with pores nearly invisible. 
Inside full of fibres radiating from the 
centre to the circumference, fibres minute 
connected by fistular concamerations. Very 
singular G. when not broken resembles the 
Oolites or mineral Balls, but inside nearly 
like a Tubipora. 1. B. Spheric a, Raf. Glo- 
bular, a little rough. In the Knobhills of 
Kentucky, petrified, diameter 1 to 2 inches. 
Almost similar to the living Tethya of Sicily, 
which has, however, larneilar fibres, and no 
concamerations. 
G5. SACONITES, Raf. 1818. Oblong 
bag suspended in tbe cavity of stones by the 
mouth, with a central axis and a little radiate 
inside. 1 . S. Gtanularis, R. Irregular ob- 
long obtuse, hag granular outside. Near 
Lexington, Kentucky, in a thin sandstone be- 
tween limestone 
66. LOBOSTOMA, Raf. 1818. Conical 
fixed, with a large mouth with unequal lobes.
