common, and from whence it was originally described. It is the first case 
of its notice in New Jersey, and, so far as I am aware, at any point east of 
the Missouri River. | 
Since writing the above, three other fragments, of somewhat smaller 
size, have been noticed among the collections made by G. C. Schanck, in 
the white limestone nodules at the base of the Lower Green Marls, near 
Marlborough, New Jersey, having the same features, placing it beyond 
doubt as a New Jersey fossil. These are in the State collections at New 
Brunswick.

This species was originally described by Dr. De Kay from an imper- 
fect fragment, but subsequently redescribed, from a very perfect cast, by 
Dr. Morton in his Synopsis. The specimen which he used is now in my 
hands, together with the outer chamber of a much smaller individual. Dr. 
Morton’s specimen is ovate in general outline, with a very ventricose outer 
chamber, which has the greatest transverse diameter below the outer angle 
of the horizontal portion, a little within the point from which rises the line 
of the hood-like aperture; above the point indicated the diameter rapidly 
decreases again to the line of the aperture. The inner coils, the number 
of which can not be determined, are laterally compressed, although they 
might be considered as ventricose for a shell of the genus, being nearly as 
large transversly as in a dorso-ventral.direction, but in comparison with the 
very rapidly increasing outer portion of .the shell, from the origin of the 
horizontal portion to the point of greatest diameter, this inner part seems 
quite constricted. From the position of the last septum, which terminates 
at the umbilicus of the inner part, the ventral margin rises abruptly, giving
