This Gepedea resembles C. Tonga in form of body, but has cilia at 

 least tAvice as long, and has spherical instead of elongated nuclei. In 

 one infection the individuals are shorter, as if they liad been formed 

 by transverse division. Chiefly because of the markedly longer cilia 

 and the different shape of the nuclei, this must be regarded as a dis- 

 tinct species. 



With this Cepedea., in the same infection are numerous specimens 

 of Protoopalina fHiformis. 



CEPEDEA SEGMENTATA, new species (fis. 1-40, p. 173).
