qual fiexuose strias above depressed, mouth 
with many Jobes. Limestone Kentucky, shi- 
elded or calcedonized. Akin to Jiscidia and 
Jfctinia. 
67. Megastoma pusilla, Raf Oboval or 
elliptical, striated, mouth nearly entire. Ken- 
tucky Limestone. A large sp of this G~M. 
cedra , elliptical rugose outside is stii! living 
in the Sicilian Sea; very near the last G. 
68. Sepiaria. Mass with many cavities 
and septas. Some are evidently organic be- 
ings, but some true minerals! Yet it is hard 
to decide The S. tesludinaria , resembling 
a petrified turtle is the most singular. 
69 GRANULITES, Raf. Branched and 
anastomosed, outside granular, inside subfib- 
rous, but solid. Almost a spongite or petrifi- 
ed sponge, but no cavities inside and outside. 
1 Gr. spongda. Branches cylindrical, irreg- 
ularly ramose and confluent, outside rough 
subgranuiar. Sandstone of Knobhills, 2 to 
4 inches, fulvous, disc. 1821. 
70. TRACT1N1TES, Raf. 1818. Fixed, 
eompJanate, lobate,with flexuose wrinkles in a 
tesselate form. 1. Tr. inequalis. Lobes very 
unequal, undulate, surface rough with some 
cavities. In Limestone, Kentucky. Silicified, 
2 to 4 inches, not two alike. 
71 BIFIDITES, Raf. 1818. Fixed, 
elongate, ending in a bifid striated appendage, 
surface granular. 1. B Scabru. Nearly terete, 
irregular, rough, granulated and wrinkled, 
appendages^unequal, undulate obtuse, stria 
ted like a shell outside. Sandstone of Knob- 
hills 
72. DERMORITES, Raf. 1818. Solid 
mass covered by a skin or tegument full of 
w» inkles. 1. D. hemispherical flat below, 
convex above, wrinkles flexuose forming flat 
oblong tubercles. Falls of Ohio in lime- 
stone, silicified 2 or 3 inches. 
73. SOMA RITES, Raf. Solid mass with- 
out skin, surface covered with irregular 
wrinkles. 1. S’. curvites. Depressed flat ir- 
regular, wrinkles curved unequal often cross- 
ing each other obliquely Knobhills sand- 
stone. ft is hard to say if this was an ani- 
mal or a plant! disc. 1818. 
74. GEODiTES. Free mass uneven out- 
side, inside hollow, often filled with crystals. 
It will be bard to decide if this G. was an 
animal or a mere mineral. Many kinds or 
sp. in the Knobhills streams. 1. G. leviga- 
ta . Globular or elliptical, nearly smooth out- 
side, cavity large, irregular, of many co- 
lours and sizes, quartzose, siheified* or calee- 
donized Observed 1819. 
75. CAVULfTES, R »f. disc 1820. Solid 
free mass, outside with irregular cavities, 
often small eavities inside. C ambloides 
Subgiobose not lobed, cavities small une- 
qual all unlike, obtuse often tabulate, few 
inside, Knobhills. silicified. 2 inches. 
Perhaps a G. of Spongite or petrified sponge, 
hut fibres obliterated.

imperfect. They are

SUPPLEMENTS. 
L Prodromus of a Monograph of 
the Gy clor it es. 
A new Genus of fossils from the Knob hills, 
&.c of Kentucky, containing S3 species, 
and the Fibril lites, 2 species. By C. S. 
Rafinesque, TS24. 
In 1821, 1 wrote the Monograph of the 
Univalve Shells of Ohio and Kentucky, 
which I sent to Brussels for publication; it 
reached that city when Mr. Bory had re- 
turned to Paris, and I have never heard 
when it was printed, nor was it sent to me 
like the Monogragh of the Bivalve. I pro- 
pose to print it again in America ; but it is 
too long for this tract. The same fate has 
happened to many of my labours sent to Eu- 
rope for publication when I was in Ken- 
tucky, such as 
1 A Monograph of the Western Tere- 
bratulites, 
2. Ditto of the Trilobites of Virginia 
and Kentucky. 
3. Essay on the Geology of Kentucky. 
4. Prodromus of a Monograph of the 
Cyclorites. 
This last was sent in 1824, to Brongniart 
and Ferrusac; but I apprehend was lost, as I 
have never heard of its reception. As it is 
not too long, I propose to add it to this tract. 
It is nearly in the same form as the Mono- 
graph of the Tiirbinolites , by Clifford and 
myself, published in 1820. 
Genus CYCLORITES. Raf. 1819. 
Tribe of Alcyonites. Body fixed or free, 
polymorphous solid, covered with one or se- 
veral openings or mouths, surrounded by 
concentric or rugose circles. 
This Genus differs from dllcyonites, which 
has no circles round the openings, from Fi- 
brillites Raf. which has the body fibrose or 
lamellar inside, and from Somarites Raf. 
which has transversal wrinkles not concen- 
tric 
It offers five different models of existence 
and organization, which must constitute as 
many sub- genera, or rather genera in my 
opinion 
The Genus was discovered by me in 1818, 
and published in 1819 in Biainville’s Jour- 
nal. 
I have already ascertained thirty-three 
species of them, which are almost all found 
in the Knob-hills of Kentucky, a spur of 
the Cumberland or Wasioto mountains, ex- 
tending from east to west nearly 360 miles 
north of the river Cumberland, while the 
Cumberland mountains divide the valleys of 
the Cumberland and Tennessee rivers. The 
Knob-hills are secondary, cut up in ridges 
and knobs, or conical hills from 200 to 500 
feet high above the Limestone plains of 
Kentucky, chiefly formed of sandstone and 
slate in horizontal strata The sandstone is 
the highest above the slate and limestone. 
It contains these Cylorites f and a multitude
