Materials and Methods

A large specimen of Pseudaneitea papillata, collected from Karori, Wellington, was narcotised in an infusion of tobacco in water. The gonad was removed after four hours, and fixed in two changes of Newcomer's fluid (Newcomer, 1953). Chromosome squashes were stained with aceto-orcein.

The same technique was used for a specimen of P. aspera, collected from the Orongorongo Valley.
