smaller and deeper than in the left valve. The muscular imprints are pro- 
portionally large, narrow, and elongated, much resembling those of Lucina; 
the posterior imprint being also the largest 
The two valves trom which the above features are taken appear to 
belong together, although they were separated when they came into my 
hands, and the right one only in fragments, with parts missmg. The hinge 
portions, however, are present, although fractured. As they fit each other, 
the features as given from them may be considered as reliable for the species.

Locality: My, Conrad’s type specimen, which is the largest, is labeled 
in his own handwriting as “Shiloh, N. J.,” and is from the cabinet of the 
Academy of Natural Sciences, Philadelphia. The others are from Bridge- 
ton, N. J., near Shiloh, and belong to the National Museum at Wash-

Mr. Conrad describes his Mysia Americana in Miocene Fossils, p. 30, 
as follows: ‘Shell suborbicular or lentiform, a little oblique, with strong 
lines of growth; hinge with two diverging teeth in each valve; posterior 
tooth of the right valve bifid; anterior muscular impression not profoundly 
elongated.” 
I have seen only one fragment, about half of a left valve, of the shell 
which I suppose to be identical with this species; but I can feel little hesita- 
tion about its identification. The only point of difference between it and 
Mr. Conrad’s figure, is the lack of a posterior sulcus in the figure, while 
there is a faintly marked sulcus on the specimen. The hinge plate, as far 
as seen, corresponds, as do all the features which are visible on the speci-
