PLATE VII 



FLAGELLATA; AND VARIOUS ORGANISMS OF DOUBTFUL POSITION 



FIGURE 16. An oval flagellate with green granular contents. One strong 

 flagellum was seen. 



FIGURE 17. A cluster of four cells, with one flagellum visible on each. The cluster 

 rotated rapidly with an irregular motion. The contents were green. 



FIGURE 18. A colourless flagellate, of ovate form with a long tail: one flagellum 

 seen : contents granular. 



FIGURE 19. A hyaline, almost spherical body, set on a slender stalk. The body is 

 marked with ten prominent annular ridges, about equidistant from one another, 

 except near the pole to which the stalk is attached, where they are crowded. 

 The protoplasmic contents form a globular mass much smaller than the envelope. 

 Identified as an encysted Podophrya, by Mr. A. W. Sheppard, F.R.M.S. 

 (see p. 22). 



FIGURE 20. A soft orange -coloured ciliated body issuing from a small opening in 

 a hyaline shell. 



FIGURE 21. A cluster of oval bodies of sienna-brown colour, in a darker brown 

 matrix. 



FIGURE 22. A soft thick-skinned animal, finely ciliate all over. Little internal 

 structure could be seen except two cavities occupying the greater part of the 

 interior. The granular part between the cavities is sienna-brown in colour. 

 Two vibrating membranes were seen, like those which are found in various 

 sorts of worms.
