Mesogastropoda del Plioceno del Empordà (Girona)

Abstract

In the present paper we describe 31 species of Mesogastropoda from the Pliocene of Empordà, Girona. For that we have taken in to account both new material and the material coming from collections that already exist. When a sufficient number of individuals was reached, the description is acompanied with the following numerical information: Maximum (M), minimun (m), the mean (x), standar desviation (s), variance (s2), mean and variance intervals, and the correlation coefficient (r).
