The different classes of mutants are described in the text.

The `polarity phenotype' is defined by the presence of bicoid mRNA at the posterior of the oocyte, whether the oocyte nucleus is mislocalised or not.

The second boussole allele (8B8-9) is included in this class,although bicoid mRNA was not detected at the posterior of the oocyte.
