 mar2GIF.gif (44455 bytes)

This is a sample of the Zoila marginata marginata form "intermedians"
from the population off Western Australia. This form was described by
Federico Lobetti Bodoni in 1986 and represents a variable population
which is intermediate in characters between the
Z. marginata ketyana and the Z. marginata marginata.
Some pecimens tend toward the ketyana, some at a midpoint and some
tend toward the marginata marginata of the Perth area.
