BULLETIN OF THE UNITED STATES FISH COMMISSION. 
Genus TRICHOPHRYA Clap. & Lach. ’58. 
(See Kent ’81; Entz’84; Butschli ’88; Sand 1901.) 
The body is spherical to elongate, usually, how- 
The tentacles are in fascicles which are usually 
Small forms to medium size; no cups or stalks, 
ever, more or less irregularly lobed and changeable, 
borne upon lobed or swollen places. 
The body is always more or less spread 
out. Contractile vacuoles variable. 
The macronucleus is spherical, elon- 
gate, band-formed or horseshoe-shaped. 
Reproduction takes place by endoge- 
nous budding, and the swarm spores 
are flat, or lenticular with a distinct 
ciliary girdle. They are frequently 
parasitic. Fresh and salt water. 
Trichophrya salparum Entz ’84. 
Butschli '88; Schewiakoff '93; Trichophrya 
ascidiarum Lachmann ’59; Rene Sand 1901. 
The body is somewhat cup-form, 
with a large, flat base. The anterior bor- 
der is rounded, each of the ends being 
somewhat truncate and carrying a bun- 
dle 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. 
This species was found by Dr. G. Hunter on the branchial bars of the Ascidian Molgulci manhat- 
tensis, where great numbers of them are often parasitic.
