[18] M. Bibron calls it T. crepitans.
[19] The cavities leading from the fleshy compartments of
the extremity, were filled with a yellow pulpy matter, which,
examined under a microscope, presented an extraordinary
appearance. The mass consisted of rounded, semi-transparent,
irregular grains, aggregated together into particles of
various sizes. All such particles, and the separate grains,
possessed the power of rapid movement; generally revolving
around different axes, but sometimes progressive. The movement
was visible with a very weak power, but even with the highest
its cause could not be perceived. It was very different from
the circulation of the fluid in the elastic bag, containing
the thin extremity of the axis. On other occasions, when
dissecting small marine animals beneath the microscope, I have
seen particles of pulpy matter, some of large size, as soon as
they were disengaged, commence revolving. I have imagined, I know
not with how much truth, that this granulo-pulpy matter was in
process of being converted into ova. Certainly in this zoophyte
such appeared to be the case.

used bows.
