In case anyone is confused,  The Nucella lapillus in question (and quite
likely most other NW atlantic intertidal shells from "Cresent Beach",
especially with a salt marsh habitat - in case anyone else has similar
lablels!!) is very probably my 1990 to 1992 collection, as repeated
below, for which someone has "abbreviated" the data, and in the process
lost the county, province and country (as well as the collector....):

        This is likely one of my colections - i'll bet at least one is a
frilly specimen, which occur with fairly high frequency at this locality
(don't let anyone tell you they only come from the Bay of Fundy!!).
I'll wager this is a result of what i like to call "data abbreviation" -
a commonpractice that occurs when someone recieves a lot with decent
data which they then decide for various reasons, to shorten.  The result
is often rather unsatisfactory - as in this case, where even the country
of origin has been "abbreviated" out of existance!!!
        "For the record", Crescent Beach is one of the best shelling
locations in Nova Scotia, with splendid salt marsh and Zostera
("eel-grass")habitats, containing about 25 species (don't laugh - for up
here that'sthe Jackpot for any given intertidal locality!!).  It is on
the SouthShore, about a 90 minute drive from Halifax - in Lunenburg
county, near Bridgewater.  (see
http://www.birdingamerica.com/NovaScotia/crescent_beach.htm
fordirections and pix: the best collecting occurs 3 or 4 times a year
onthe lowest of tides - if you plan a shelling trip to this neck of
thewoods the timing is absolutely critical!!   The Zostera stands
arefascinating: a dozen mollusc spp. inhabit the algae-covered blades
ofsea-grass - some feeding upon it, such as a specialized, elongate
formof Tectura testudinalis that locally fills the niche of the extinct
Lottia alveus, to predators such as Nucella (oddly enough,
oftenfrilly!), which feed on the herbivores: it is a well-developed
miniature ecosystem that would make a great masters thesis for someone sometime....
