californica, radulae and copulatory spicules were isolated with warm potassium hydroxide or with sodium hypochlorite (standard household bleach) and thoroughly washed after dissecting anterior and posterior ends.
Radulae of more than 100 genera of non-truncatellid rissooideans have been illustrated by various authors; all have a trapezoidal central (rachidian) tooth, as do geomelaniines [ILLUSTRATION FOR FIGURE 6B OMITTED].
Cleaned radulae were mounted in a water-soluble mounting medium (polyvinyl lactophenol) to make a permanent slide.
Radulae were prepared by dissolving buccal masses in 20% KOH at 20-30 [degrees]C, rinsing in distilled water, and mounting on a bed of PVA glue.
Descriptions and illustrations of radulae and distal genitalia are provided for operculate and stylommatophoran species respectively.
Although the basic design of chiton and limpet radulae is similar, the radular anatomy of chitons provides a far greater degree of lateral flexibility compared to limpets.
The radula from the single specimen of Paralepetopsis tunnicliffae was mounted for SEM; radulae of the two other new species were whole-mounted in stain-suffused, nonresinous mounting medium.
Radulae were extracted by maceration of the buccal mass in dilute NaOH and then thoroughly rinsed in distilled water.
