Item description from seller

Discriminant function analysis was used to develop a simple and practical formula for classification of a sample made up of two morphologically very similar species, Vitrea contracta and V. crystallina. By using three variables: number of whorls, breadth of the last whorl and height of the shell, a discrimination function was obtained which effectively discriminates between the problematic young specimens of these two species. Probability of misclassification of a small individual is 0.02. 6 pp., 4 figs, gr. 8.
