The pedal disc was l>road anil irregularly folded, that of the damaged specimen drawn out in two portions, the one considerably longer than the other. The column irregularly wrinkled. I cannot decide if cinclides were ])resent, considering the thickness of the mesogloea they were jiossiblv alisent. Anatomical description: The textfigure 26 shows the structure of the sphincter. The mesenteries were more numerous at the base than at the margin. Owing to the strong and irregular contraction of the pedal disc it was very difficult to decide the exact number of the mesenteries at the base without demolishing the specimen. In about three fourth of the limbus I counted, how- ever, about 100 mesenteries, wherefore the number of them m
