1. Spores (after Ohlmacher. Leitz pantachromatic oil imm. 2 mm., oc. 4. X 1). 

 1«. Vertical view of spore, showing capsules with extruded tilaments. Camera 



lucida; Babes's anilin water safrauin. 

 li. Vertical view showing capsules, spiral-coil structure of shell, and vertical 



position of ridge. 

 Ic. Striae are seen "running nearly meridionally "; at one "side" of spore a 



ciipsnle "appears in the act of escaping throngh a rent" in the shell. 

 Id. Fragment of shell in which the striie appear to corresi»ond to ridges 



encircling the shell. 



2. Kidney tubule, inclosing 3 spores, showing capsules and sporoplasm, the lat- 



ter structure being represented in 1 spore as divided into L' lateral halves. 

 (An error; see p. 270.) Pfitzner's alcoholic safranin (after Ohlmacher; 

 camera lucida; Leitz pantachromatic 3 mm., oc. 4. xl). 



3. Diagrammatic figure of spore; a, shell; b, sporoplasm; c, capsule; d, posterior 



extremity of ridge aud spore; e, ridge; /, anterior extremity of ridge and 

 spore; g, filaments, much shortened; a, b, e, are on the lett side of spore; 

 c on the right. (After Whinery. X 1).
