Exterior aspect: The pedal disc is wide. The body is, according to the state of contraction, cylindrical, conical or flattened, in contracted specimens the height of the column is commonly shorter than the diameter of the base. The column is furnished with lines of verrucae which appear more or less distinctly, according to the state of contraction. In a part of the specimens I have not been able to verify with certainty the presence of verrucae, it may be possible that such ones are sometimes lacking, which is very difficult to determine in contracted and badly preserved material, above all as the verrucae are rather small. I have, however, obser\-
