 14. LtrciLiTES Nigra, a new univalve fossil Shell, from the 



Alleghany Mountains of Pennsylvania. By G. S. Rafinesque. 



This pretty fossil is in the Cabinet of my friend Hayden, in, Balti- 

 more, who found a single specimeii 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. Itsblack 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 



[117] 



only differs from Patella, by being elliptical and smooth, without 

 radiations. , 



G. Lucilites Eaf. 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 breadtK. Over half an inch in the 

 specimen

22. CoNCHOXiOGY. — A New Tubular fresh water shell of the Alle- 

 ghany Mts. 



1 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. It is not therefore the tube of
