es are flat or lenticular
with a distinct ciliary girdle. They are frequently parasitic. Fresh
and salt water.

The body is somewhat cup-form, with a large, flat base. The anterior
border is rounded, each of the ends being somewhat truncate and
carrying a bundle of tentacles all capitate and similar. These may be
continued internally as far as the nucleus (Sand). The cytoplasm is
uncolored, but may contain some brilliant granules. The nucleus is
granular, and spherical, band or horseshoe formed.

[Illustration: Fig. 69.--_Trichophrya salparum_.]

This species was found by Dr. G. Hunter on the branchial bars of the
Ascidian _Molgula manhattensis_, where great numbers of them are
often parasitic.
