105. Stratipora and Fxexxt- 
XXTES N. G. 
These are 4 two N. G. of fossil 
polypites of my cabinet. Roth 
are from the fine fossil regions 
south of the Apalachian mts. 
where so many new shells have 
lately been found . They are not 
silicified. 
1. Stratipora Raf. Mass of 
Basaltic angular cells like Favo- 
sites, but short not concamerated, 
top with several regular rows of 
equal round pores like Millepore 
each corresponding to a tube.... 
Very singular N. G. with the 
general form cf Favosite, and 
the internal structure of Mille- 
'po-re; tribe.: 
Sp. ( Sir a tiporalreoissiina Raf. 
Basaltic pi! tars not stri ate d’ com- 
monly hexagone, 2 opposite sides 
longer, even at top, but unequal 
in. length 'beneath, forming an 
extended flattened level mass. 
From Louisiana near the River 
Teche, specimen 4 inches by 3, 
pillars from 1-4 to 1-2 inch long 
only, of a greyish , color, marly 
smelling of day but very bard, 
eed ed to me by Professor Green, 
who deemed it wrongly a Tubi- 
pom 
2. Fxexuixtes; Raf. Body 
fixed obconic, outside with a 
thin tegument covered with flex- 
uose wrinkles, inside solid filled 
with minute transversal liexuose 
fibres or strias.... Another very 
singular and anomalous N. G. 
akin to the Madreporites,but no 
stellated mouth, inside not radi- 
ated, but irregularly liexuose. 
Perhaps it is a fossil Pcrostome 
or animal without mouth as Te- 
thya, &c. 
Sp. Flexulites Jiaydeni Raf. 
Body obconical truncate, snbag- 
regate, outside flexules transver- 
sal, each raised and with a fur- 
row on it, internal flexules in- 
termixt becoming less near the 
surface.... Specimen 4 inches long 
changed into a silicious grey 
slate, upon a rusty slate, from 
the region south pf the Apalachi- 
an in Alabama. Ceded to me 
by Mr. Hayden to whom I have 
dedicated the sp. C. S. R. 
106. New LizArd 'prom Ken- 
tucky. 
It was observed in 1823, on 
the Knobhills of West Kentucky 
not far from the Mammoth cave. 
It is called scorpion and errone- 
ously deemed poisonous, like 
most of our Lizards. It is ra-
