 narrower, and the lateral teeth possess broader bases, than the figures of Sars (Is7s)and

 specimens from 4-12 mm. in length. In some of these the retractor muscle, instead of 

 extending 1-2 mm. beyond the end of the gonad, stretches to 4/50 mm. beyond this 

 organ, dragging the visceral envelope with it, so that the animal presents an extra-
