The prostomium (Fig. 11, <7) is subrectangular, and there are two pairs of large eyes both set rather far back and to the sides.

The palps are as long as the head and the first seven chaetigers, and the tentacular cirri are about two-thirds of their length. All the appendages except the palps, which are thickly covered with small papillae, are very hirsute. Below the median tentaculophore is a small digitiform process (sub- tentacular cirrus), which is probably a facial tubercle. From just above the junction of the tentaculophores of the tentacular cirri on both sides is a bundle of about half a dozen stout bristles pointing directly forwards.
