Hola Victoriano,

Erosaria spurca extends its range from the Mediterranean Sea to Angola all
along the West African coast, including Canaries and Cabo Verde Islands.

According to Lorenz (2000), 'verdensium' (Melvill, 18888) must be considered
an Atlantic form of E. spurca, because differences between them are not too
constant. ('verdensium' presenting more dense spotting, thicker teeth and
narrower aperture)

'cascabullorum' (Talavera et al., 1986) is regarded as a variety (i. e. less
than a form) of E. spurca, more tiny and living deeper.

Best regards,

Alfonso
