117. Conch ology. Two New Bi- 
valve Fluviatile Shells of S. 
America, By C. S. Rafinesque. 
These two fine shells are from the 
Cabinet of Professor Green, who 
permitted me to draw them and de- 
scribe last March. They are both 
from the R. Parana above Buenos 
Ayres. 
1. Anodonta aperta Raf. Oval 
elliptical much swelled, broader be- 
hind and slanting, very smooth and 
dark brown outside, quite gaping 
below, iridescent white inside. Length 
and diameter l of breadth, axis at |. 
...Fine large sp. 6 inches broad, shell 
rather thick, beaks proeminent, not 
gaping at the ends but below; hinge 
streight slanting ending in 2 small 
angles, no wrinkles on it, but slight- 
ly flexuolate beneath. 
2. Unio paphos Raf. Oval, flexu- 
ose and subtruncate behind, with an 
obliqual ridge from the beak, brown 
outside with many minute concentric 
strias, inside purplish white. Length 
2-3, diameter 7-18, axis at 1-3 of 
the breadth.—Pretty Sp* 2 inches 
broad, shell rather thin for Unios, 
lamellar tooth slightly curved, car- 
dinal tooth sub-bilobe crenate. Beaks 
not prominent. 
118. ODATEL1A N. G. of N. American 
Bivalve fuviatile shell, by C.S.Rajinesque . 
One of our Ohio shells, which has been 
put with the Unios or Anodonta by diffe- 
rent writers; it was unknown to me till I 
observed it in Prof. Green’s cabinet, and 
1 immediately ascertained that it must 
form a N. G. or group between Anodonta 
and Sulcularia. 1 call it Odateha meaning 
Imperfect teeth. 
Ohatelia Raf. Cardinal tooth imper- 
fect like a callosity, with alarge desineose 
as in Alasmodon , becoming an imperfect 
lamellar tooth angular as in Lasmigona ..«. 
This G. must belong to the series of Am - 
donta , but forms the passage with Alasmo* 
don. How Say and Lea could put it with 
Unio! is rather strange. 
Odatelia radiata Raf. Elliptical flatten- 
ed elongate, broader behind with sub- 
truncate end* outside olivaceous brown, 
with black ray?, inside bluish iridescent. 
Length 1-3, diameter 2-9, axis at 2-9 of\ 
the length. 
Unio Oriefis. Lea. 
Unio dehiscens. Say. 
Anodonta prelong a. Green. 
Breadth over 2 inches, shell rather thin 
both ends rounded and brown.
