how before me, all of the S, G. Pericydites. 
31. Sp. Cyclorites proeminens. 
Rounded amorphous smooth, several 
circles raised proeminent scattered, wrinkles 
1 to 3 thick large convex. Yellowish l inch. 
32. Sp. Cyclorites dianisa , or JY. G. Di- 
anisites elliptica , elliptical flattened, margin 
tabulate, surface uneven, one large circle 
above with one elliptic wrinkle, containing 
two unequal circles, with few prominent 
knobby wrinkles, centre convex, whitish, 
two inches. Intermediary between C 
duplicata and Crenata. It may form a 
S. G with C. dupticata and the following: 
the Dianisites distinguished by body free de- 
pressed , having above a single circle contain- 
ing 2 or more smaller circles inside. 
33. Sp. Cycloriles striata or Dianisites 
striata. 
Rounded, convex and rugose below, flat or 
concave above with a large circle occupying 
the whole surface, the margin broad, flat, 
striated, and rugose across, two unequal 
internal circles with many minute wrinkles 
centre concave — Fulvous 1^ inch, very rare 
Remarks. The above fine and prolific 
Genus, must be found elsewhere also* I 
suspect that some ocuiated calcedonies of 
Siberia belong to it. Patrin long ago stated 
that they might be organic remains. They 
must always be easily distinguished from the 
mamillar calcedonies which appear real 
minerals and semi globular crystals by their 
external organised appearance, although the 
inside may he changed into pure calcedony 
Many of the above species are probably 
mere indurated parts; the mouths or open- 
ing are akin to some Sp. of Jllcyonites and 
Jlscidiles , which however have no concentric 
circles. The Jhcyonium tribe is well known 
to be next to sponges, and the lowest in the 
scale of sea animals. 
To dispel the least objection of my theory, 
another beautiful new Genus, my fibrillites 
will be described, which is outside exactly 
like cyclorit.es , but has a fibrous organised 
structure. I have now before me two 
species of it, one of which is half calcedonised 
and internal structure half obliterated, which 
may lead to a belief that the cyclorites might 
also have had an organised interior which 
has been quite obliterated by lapidification. 
G. FIBRILLITES disc. 1820. 
Body free, solid or cavernous, interior 
with minute fistular fibres, ending in very 
minute pores on the outside surface, which is 
covered with concentric circles as in 
Cyclorites. 
Fine marine Genus now fossil, very near 
to the G.Telhya of Donati, which has similar 
fibres inside; and to another N. G. of 
Kentuckey fossils, the Bolactiles , No. 64. 
They are all from the same geological region. 
1, Sp. Fibrillites cavernosa Elliptical, 
cavernose fibres curved radiating, surface 
with many large concentric circles unequal 
confluent rounded, several thick and irregular 
wrinkles, centre concave or convex — 
yellowish, four inches, beautiful specimen^ 
unique and very valuable. 
2. Sp. Fibrillites amorpha. Amorphous 
solid, obliterated except in the centre, and 
the visible pores of the surface, which is 
knobby uneven; concentric circles raised 
small, 1 or 2 wrinkles thick, irregular, 
centre excavated. Smaller, redish, pale 
where quite calcedonised.
