Tarebia granifera Littoridinops tenuipes Small- or medium-sized snails need to be identified with the aid of a binocular dissecting microscope that is equipped with an ocular micrometer calibrated to 0.1 mm accuracy so that precise measurements can be made. They are brown in color and have a striped pattern. Smooth-ribbed Hydrobe 202, 208). Opercula of minute snails can be studied most easily by removing them from the animal and viewing them with transmitted light. Live field samples should be divided into two groups, one to be preserved for shells, the other to be preserved for anatomical specimens. Spire of adults without distinct vertical ribs.
