21. The shells are dextral and have a very high and narrow lirate ( i . e . finely lined or grooved ). 22. From a tentative correlation of the fault zone with the similarly NW-SE striking dextral Jurassic Gastre Fault System ( cf. 23. The dextral " South Finland Shear Zone " runns across much of southern Finland in a west-east direction. 24. Note that Pilsbry described the shell as if it were dextral , whereas planorbids are now known to be sinistral in shell coiling. 25. Lateral parietal cortex damage ( either dextral or sinistral ) impairs performance on recognition memory tasks, but does not affect source memories. 26. After aftershocks from the quake had concluded, examination took place, producing a shearing on the right-lateral ( dextral ) side. 27. Of seventeen shells collected in May, 1954, by Hoogerwerf at Telaga Kastoba, Bawean Island, ten were dextral and seven sinistral. 28. In the Donzenac Schist, where both shear senses are present, one can observe how the dextral shearing is overprinting the sinistral shearing. 29. The shell aperture is located on the right side, i . e . the shell of this species is almost always dextral in coiling. 30. Indeed, formerly planorbids were thought to have dextral shells, and so species of this family were figured as if they had dextral shells.
