Pseudosuberites nudus

Dendrilla membranosa

Eulagisca gigantea

Two of these specimens are gigantic Polynoids. That from Sta. 30 is the largest, and measures 148 mm. by 31 mm. (without the feet) for 37 chaetigers. The other large specimen is from Sta. 107, and measures 110 mm. by 20 mm. (without the feet) for 37 chaetigers. The third specimen is much smaller, and measures only 60 mm. by 12 mm. (without the feet), also for 37 chaetigers. There are 15 pairs of elytra arranged as in Harmothoë. Except for t...View more
