Steinhatchee, Taylor County, Florida Vicinity
    Below is a cumulative list of the non-marine mollusks collected by Harry G. Lee at Steinhatchee Falls (10/26/05 and 1/26/06 [litter sample by E. W. Cavin]) and, while the guest of Mike and Jane McCullagh, by visual reconnaissance and litter sampling on the premises of the Steinhatchee Landing neighborhood (4/28/06,  11/14/06, and 10/17/07), Taylor County, Florida. An asterisk (*) denotes a new county record (24 of the 30 native species) vs. Hubricht (1985). The stark contrast between this ratio and that of the Levy Co. collections above (9 of 30) is a clear reflection of the differential emphasis by previous collectors, as Hubricht (1985) indicated 33 species for Levy Co. and only nine for Taylor.

    These published records in turn reflect the collecting patterns of Hubricht himself, who personally produced at least 24 species records for Levy and only 11 for Taylor Co. according to the database including the Hubricht Collection at the Field Museum of Natural History (FMNH), Chicago.* Assuming the FMNH's extensive holdings are a true representation of what Leslie Hubricht collected in the field, we can make a comparison between his style of collecting and the "saturation" technique (including litter sample analysis and Euglandina evisceration) employed by us. From 1959 to 1982 he established 40 stations and collected 78 lots of land snails in Levy Co. - that's only two lots per station on average. Likewise his efforts in Taylor Co., from 1970 to 1978 produced 35 lots from 24 stations (average 1.5 lots per station). An taxonomic analysis shows that species with an adult shell size of less than 6 mm constituted 18 of the 78 Levy Co. lots and only two of the Taylor Co. 35 lots. Clearly Mr. Hubricht was on the prowl for larger snails - in particular the charismatic polygyrid taxa (30/35 and 54/78 lots respectively) - exemplified by Daedalochila spp. (22 and 30 respectively), which, by contrast, we found quite elusive. The proportion of small species (< 6 mm.) at any of our stations is over one half.

    Note that 14 species in this list (highlighted in yellow) were not collected in Levy Co. and the same number vice-versa (likewise highlighted; above). The most likely explanation for the poor overlap is inadequate sampling as all but two of the 47 species found in either county have been found in northeast Florida, where years of intensive collecting have produced a total of 78 species.

* There are minor discrepancies between the monograph and the FMNH collections database.

Florida Caverns State Park, Marianna, Jackson County, Florida

    Land snails collected from 12/3/89 and 10/30/07 litter samples [H. McCullagh!], on Jacksonville and Gulf Coast Shell Club joint field trip, and H. Lee/H. McCullagh field trip to the vicinity of the Florida Caverns State Park, Marianna, Jackson Co., Florida [each of the latter two include visual reconnaissance plus litter samples, 10/13/90 and 4/12/08 respectively]. Twelve of the species (*) are county records vs. Hubricht (1985). Although only two of the composite 44 species from Taylor and Levy Cos. (Daedalochila bicornuta and D. sp. A) meet the same criterion, ten species (highlighted in blue) are not among the 78 found in northeast Florida. These plus six others (highlighted in green) are absent from Taylor and Levy Co. collections. Most likely the ten in blue represent elements of a distinctly different fauna, and those in green mere undersampling in the latter two counties.
