always shady, damp, and covered with mosses and ferns. I collected the shells 
on the ledges of the rocks among the dead leaves, at an elevation above the 
river of about 100 feet. I have not found either of the species in any other 
locality.” 
Mr. J: H. Thomson, to whom I submitted specimens, sent to me examples 
of the same species collected by him, “on a high rocky ledge, covered with old 
trees, at Tiverton, Rhode Island.” 
This species, Z. Wheatley, is more nearly allied to Z. viridulus, Menke, than — 
to any other North American form, but differs from it, especially in the form 
of aperture, in the descending last whorl, and in having a wider umbilicus. 
_I dedicate the species to the memory of my late valued and lamented friend, 
Charles M. Wheatley. (Bland.)

Dr. Dall gives the number of whorls 44-5. A copy of his 
original figure is here given, as mine is said by him to be 
incorrect. 
Zonites capsella, Goutp. (p. 123.)

The true capsella has 15-1-15 teeth on the lingual membrane, two on each 
side of the median tooth being true laterals; the fourth is a marginal.
