A fascinating book that proved to be an extraordinarily useful reference work for southern African marine biologists as well as
malacologists far and wide, and one that has been extensively cited.
Indeed, the great
malacologist Johannes Thiele, with far less information than is now available, and who published over 20 aplacophoran species descriptions, concluded that aplacophorans were not molluscs as such, but phylogenetically between annelids and molluscs and ancestral to the latter (Thiele, 1913c; Glaubrecht et al., 2005).

Certain
malacologists (scientists who study mollusks) study a group of snails called cone snails.
Species were identified using Cummings & Mayer (1992); for nomenclature, the list of common and scientific names of mollusks prepared by the Council of Systematic
Malacologists and the Committee on Scientific and Common Names of the American Malacological Union was followed (Turgeon et al.
He added: 'Quite recently the name for shell collectors has been changed from conchologists to
malacologists - a term which refers not only to the shells, but also to the study of the animals inside them.
Despite the classic explorations and descriptions of such collectors and
malacologists as W.
In the upper Susquehanna basin trained
malacologists (Arthur Clarke, Clifford Berg, Willard Harman, Carol Stein and their colleagues) surveyed mussel communities at nearly 70 sites between 1955 and 1965.
However, they should be proud to have produced this study, which will be useful to
malacologists, ecologists, conservation workers, archeologists, and people who happen to pick up a mussel shell along a streambank and wonder about it.
In view of the extensive intraspecific variation known to occur in species of Nucella and the overzealous naming of shell variants by early
malacologists (reviewed in Palmer et al.

Williamson amassed a significant collection of shells, corresponding extensively with
malacologists from around the world.
All material of this species was originally in the collection of Adolfo Ortiz de Zarate Lopez, who exchanged Fernando Poo land snails with various professional and amateur
malacologists. Only four specimens of A.
Such temporal recruitment patterns should not be surprising to
malacologists with a working knowledge of bivalves with a life expectancy of l0-20 y, arguably typical in pristine oyster populations prior to human impacts on their habitats.
Malacologists, working in the southern Glacial Lake Agassiz region (e.g., Wilson and Danglade, 1914; Dawley, 1947; Cvancara and Cvancara et al., see below; Clarke, 1973, 1981) and elsewhere (e.g., Simpson, 1896; Ortmann, 1924; Johnson, 1970, 1980), recognized the effect of the latest Pleistocene (Wisconsin) deglaciation on the distribution of freshwater pearly mussels (Bivalvia: Unionoidea) in the Canadian Interior and Great Lakes basins.
