Beure (2010) reported on specimens collected ca. 55 km North-West of Mayoc.

Description

Haas (1955) also noted that the colour pattern varied more in the specimens from near Mayoc and Locroja. The variety in patterns, from uniformly greyish-white to uniformly streaked at irregular intervals, is also observed in material collected by Breure (2010). The aberrant pattern noted by Haas, viz. streaks with ‘lateral, triangular appendages that tend to be arranged in spiral rows’ has been observed in a single shell from the series examined by Breure (2010).
