The size of the shell varies between 4 mm and 8 mm. This species form differs from typical Gibbula tumida in the constant smaller size, fewer whorls (4 to 5), and generally more solid and deeply colored shell. It is variable in proportions, frequently as broad or broader than long.^[2]

Distribution

This species occurs in the Mediterranean Sea and in the Atlantic Ocean off Portugal.
