The term 'heterostrophy' (Figs. 4d and 7a, b) has been used for this condition (
e.g. Knight 1941, 1952). If all the shell whorls are coiled in the same direction (i.e.
dextrally or sinistrally), we call the shells 'homeostrophic' (Fig. 4h). Some authors
...

Perspectives in Malacology
Systematic list of Recent gastropods hypothesized to have homologous
heterostrophy (HET), including hyperstrophy of some adult thecosomes, and
hyperstrophy of some larval ascoglossan and nudibranch slugs. Term applied (
key words) ...

Architectonicidae of the Indo-Pacific (Mollusca, Gastropoda)
Heterostrophy. The body of an architectonicid larva is dextrally organized. This is
demonstrated externally by the operculum (see Fig. 17). In dextrally organized
animals the spiral line on the outside of the operculum is directed ...

The pyramidellid shell is variably shaped, with the protoconch showing a change
in the direction of coiling called heterostrophy (Fretter and Graham, 1 949; Fretter,
et al., 1986; Wise, 1996; Ponder and de Keyzer, 1998). Two forms of ...
The subgenus Hendri^ia Preston 1913, based on Hendrifca mtri/ica Preston,
agrees in all respects with the predecollate stages of Pythia icarabaeus as
outlined above, and is obviously invalid. Conclusions Heterostrophy among the
Ellobiidae ...

AMERICAN MICROSCOPICAL SOCIETY: TRANSACTIONS
Heterostrophy: The larval shell of A. canaliculata, like other planktotropic
opisthobranchs, is hypertrophic, i.e., the symmetry of the shell is opposite that of
the animal. The larval shell is coiled sinistrally, but the fundamental symmetry of
the ...

Just 2 publications report land-slug lung openings on the left, in Umax and Arion,
both dating from the last century.566 Heterostrophy (larval hyperstrophy) occurs
in (all?) the Architec- tonicidae (sundials) and Mathildidae, some (but not all) ...

Boston Journal of Natural History
This species is easily distinguished from the Ccrithium reticuldtum, not only by
the obvious character of heterostrophy, but by others more important, and too
evident to require remark. It is more nearly allied to the C. pervérsum, Lam., from
...

Geological Survey Professional Paper
The initial whorls are generally deviated, ranging from complete heterostrophy in
some of the species of Mathilda to slightly deviated or even submerged and
deviated, as in Gegania. Until more detail is known of the soft parts of the living ...
