### Abstract

The Spiral Shell Form was developed as an original computer software package designed for theoretical morphological analysis of gastropod shell forms using the Raup's model. It is composed of the following three programs. Spiral Shell Measure is a software for capturing coordinate data of the points of interest on computer image files of a specimen. Raup's Parameter Calculator is a Mathematica program for calculation of Raup's parameters from coordinate data that were collected using the Spiral Shell Measure. Spiral Shell Properties is a Mathematica program for computing physical properties of a theoretical model such as shell volume, area of the aperture, center of gravity, soft-body ratio and length of trajectory of centroid of aperture.
