Dear Harry,
Trichia hispida and T. striolata have both
been found in Newfoundland, Canada. T.
striolata is restricted to the southeast area
of the province, mainly in the St. John's
area. T. hispida is found in scattered
localities around the province.
Specimens of both species are in the
collection of tbe Newfoundland Museum, St.
John's, Newfoundland, Canada.
I hope that this information is helpful to
you.
Malacologically yours,
Ron Noseworthy

Thanks, Lubosh.
I misspelled Cochlicopa (as Cochliocopa).

Subject: Exotic landsnail in North America
Dear Listers,
Awaiting the airport shuttle vehicle while
concluding a short stay at
the La Tourelle Inn on the outskirts of
Ithaca, New York, I decided to
take a look around a half-acre artificial
"fishing pond" on the
spacious premises. The setting was a
picturesque hillside
overlooking Lake Cayuga to the northwest. The
weather was mild for a
mid-November day; Ithaca had gotten very
little snowfall this
autumn.
Ignoring the few gawkers, I nosed around the
pond's margins and
easily found a fair number of living
landsnails on the lawn, especially
under hewn larger weeds. There were four
species - Novisuccinea ovata,
Cochliocopa lubrica, a small nearly black
slug, and, most abundantly, a
quarter-inch globose snail I thought to be a
Slit-mouth (Stenotrema) of
some sort because of its having
Pussy-willow-bud-like texture. I popped
the snails into an evacuated (and fully
thoroughly-rinsed) shampoo
sampler supplied by the inn, pocketed the
collection, and shuttled to the
Ithaca Airport. While languishing in La
Guardia, I inspected the
shells more closely and saw a densely hirsute
Stenotrema-like
periostracum accounted for the shell's
unusual surface but no evidence of
the thickened lip and constricted aperture
that characterizes that North
American genus. After some reflection, my
mind finally broke loose from
the box, and I considered this critter might
be a non-native
species.
On arrival in Jax that night, despite
temporary dismay with the
Jaguars' last minute loss to the Titans, I
went to microscope and books
and sorted out the identity of this probable
vagabond. Conclusion: I had
picked up my first (and two dozenth) Hairy
Helicellid, a species native
to northwest Europe east through northern
Asia to the Amur River.
Taxonomically it is known as Trichia hispida
(Linnaeus, 1758) [literally:
the Hairy (Latin), Hairy (Greek) Snail]. Its
phylogeny is like this:
Mollusca: Gastropoda: Stylommatophora:
Pulmonata: Helicoidea:
Hygromiidae: Hygromiinae.
I am unaware of any records outside ME and MA
in the USA (plus NOVA
SCOTIA, PRINCE EDWARD ISLAND, NEW BRUNSWICK,
QUEBEC, and ONTARIO in
Canada), I thought I'd ask the likes of Tom
Watters, Richie Goldberg,
Larry Watrous, Aydin Orstan, and other
listers if they can fill me in on
this species' peregrinations in North America.
