14. Lucrmuires Niagra, a new univalve fossil Shell, from the 
Alleghany Mountains of Pennsylvania. By C. S. Rafinesque. 
This pretty fossil is in the Cabinet of my friend Hayden, in Balti- 
more, who found a single specimen of it, on the side of a limestone 
cliff at Bedford Springs, in a valley of the Alleghanys of S. Penn- 
sylvania. It was taken 60 feet from the ground. It is the most 
shining fossil Shell which I have seen, almost as if recent, whence I 
have called it Lucilites or shining fossil. Its black color very un- 
natural among shells makes a fine contrast with the dull blue lime- 
stone in which it is fixed. It belongs to the familly of Patellites, and 
(2117) 
only differs.from Patella, by being elliptical and smooth, without 
radiations. 
G. Lucilites Raf. Simple univalve pateloid shell. Elliptical 
entire, outside convex smooth without radiations, inside concave 
smooth. No openings or fissures. 
Sp. L. nigra. Black shining outside, both ends equal obtuse. 
Length double of the breadth. Over half an itch in the 
specimen

22. ConcnoLocy.—A New Tubular fresh water shell of the Alle 
ghany Mis. 
I was much gratified to find this year a new fluviatile shell of the 
simple tubular form ; but the animal was not within. It was found 
in Sherman creek, a mountain stream of Perry County, Pennsylvania, 
among the Alleghanies. 
This strange shell has something mysterious in it. It appears a 
mass of gravel; strongly cemented, even holding sometimes minute 
fossil terebratulites and other fossils. Itis not therefore the tube of
