Springfield, Febry 6th 1856.

Friend Kennicott,

On my return from New Harmony,
a few days ago, I found your letter, and got the box of
snails and a copy of the Report from Mr. L. Francis.
Your apology about the Lake shells is quite acceptable,
as it is of the greatest importance, that Illinois river and
Lake shells should not be confounded. I have not as yet
put up my collection, and therefore after the determination
of the Gasteropods you sent me, for a short time. N^o 2
is an Amnicola, probably A porata, I never saw it in
Southern Illinois. Don't varnish you[page torn] H. monodon, be-
cause it destroys the beautiful fur, with which the epidermis
is covered in perfect specimens. Your N^o11 is quite a new
acquisition in the West and indeed [page stain]ll America - it is
a European species, H. hortensis, and has probably been
imported in t[page torn] roots of fruit trees or by some similar con-
veyance. Keep a sharp look-out for them, and let me know,
whether there are many of them. Prof. Gould of Massachusetts
has found the same species in the East, where it is beginning
to propagate. N^o 13 is unknown to me, I should call it an
H. tridentata, if it were not for its open umbilicus.

As soon as I shall have arranged my specimens, I shall
send you the names of your snails as far as I can make them
out. Meanwhile let me hear from you. My respects to your
uncle I. A. Kennicott. Yours etc. H. A. Ulffers.
