DESCRIPTION OF PLATES X-XV. 
All the figures, except diagrammatic ones (Figs. 13, 15, 35, 53, 75, 82) were drawn with a 
camera lucida. The optical apparatus employed was as follows: Zeiss stand IA, immersion 
objective ff', and Huygenian oculars 2 or 4; tube of microscope not drawn out, and fitted with 
revolving nosepiece. Drawings made at level of stage of microscope. The dimensions of the 
organisms are stated in the text. In some figures the surface of the organism is drawn at the 
lower focus, so that the spirals appear reversed. All figures drawn from specimens fixed with 
sublimate-alcohol (Schaudinn) and stained with iron-haematoxylin (Heidenhain)—using, however, 
the haematoxylin in alcoholic solution.

(In Figs. 32, 34, 36, and 37, the specimens are drawn focused on lower surface, so that the
