palp

The mandible has a two-jointed palp (Fig. 3), with numerous hairs along the outer margin.

First maxill (Fig. 7) two-jointed, palp and second joint armed with spines.

Behind this jaw is a short leg, formed like a walking leg, and known as the 'palp.'

Before the close of the Zoa condition a small and unjointed palp appears on the mandible.

The two rami of the mandibles are reduced to a simple palp, while the blade has assumed its full importance.
