FIGURE 4 in The genus Acicula W. Hartmann, 1821 in the Caucasus (Gastropoda: Caenogastropoda: Aciculidae)

FIGURE 4. Shape changes along the CV1. The starting shape (i.e., A. moussoni in the leftmost graph) is shown as light blue outlines with hollow dots at the positions of the landmarks, and the target shape (i.e., A. parcelineata in the leftmost graph) is shown as a dark blue outline with solid dots at the positions of the landmarks. Scale factor = 5 (the scale factor is the magnification or reduction applied to the shape as a Procrustes distance, that is displayed).
