Found by Bullington (1940) several times on algae in

 with the Gulf." 



Suborder 3 Trichostomata Biitschli 1889 

 Family ENTORHIPIDIIDAE Madsen 



20. Enlodiscus sabulonis Powers, 1935. 



Found by Powers (1935) in the intestines of sea urchins, 

 Clypeaster rosaceus and C. subdepressns, in shallow water 

 at Tortugas. 



21. "Form L" Powers, 1935. 



Powers (1935) considered this unidentified ciliate infest- 

 ing Clypeaster subdepressus in Tortugas to be either a 

 variety of E. sabulonis or a closely related species. 



22. Biggaria bermudensis (Biggar, 1932). 



According to Powers (1933, p. 279), "While this species 

 may be found in any echinoid host, it seems to prefer 

 Lytechinus variegatus or Tripneusles esculentus," infesting 

 their intestines. The species is considered by Powers 

 (1933, 1935) as identical with form "D" which Jacobs 

 (1911) discovered at Tortugas and indicated that it has 

 been observed also at Bermuda and Beaufort, North 

 Carolina. 



23. Anophrys elongata Biggar, 1932. 



According to Powers (1935) this ciliate is identical with 

 form "C" of Jacobs (1911). It was found at Bermuda and
