openings turned in one direction, and a long bristle above 

 each cell. On zoophytes. 



658. SNAKE CORALLINE (Atuptsnaria spafulata). 

 Creeping, club-shaped cells, bent at the upper portion, 

 rise at irregular intervals from the creeping, fibrous stem. 

 Parasitic on seaweeds. 



659. MAIL CORALLINE (Gemellaria loriculata). Very 

 bushy; the branches slender, thread-like, and numerous. 

 Cells smooth, and in pairs. Growing below low-water 

 mark. 



660. ROUGH CELLEPORE (Cellepora pumicosa). Cells 

 conglomerated into a calcareous mass, encrusting other 

 bodies, rough and porous. Aperture sometimes with a 

 short tooth. On stones, zoophytes, and seaweeds. 



661. RINGED LEPRALIA (Lepralia annulata). Crusta- 

 ceous on seaweeds. Cells unshaped, with transverse rows 

 of punctures. Opening surrounded by a smooth rim. 

 (PI. VIII., fig. i.) 



662. PUNCTATE LEPRALIA (Lepralia punctatd). Crus- 

 taceous; cells almost cylindrical, with transverse rows of 

 obscure punctures. Opening roundish, uneven, with three 

 or four obsolete teeth on the rim. On rocks and old shells. 



663. ROUGH LEPRALIA (Lepralia variolosa}. Crusta- 

 ceous ; cells oblong, depressed, roughish, punctured be- 

 tween the cells. Opening roundish, with a plain margin. 

 On stones and bivalved shells. (PI. VIII., fig. 2.) 



664. ONE-HORNED LEPRALIA (Lepralia unicornis). 

 Crustaceous; cells ovate, scaly, with a short knob above 

 the opening, which is roundish, with a distinct notch in 

 the upper margin. On rocks and the roots of seaweeds. 

 (PI. VIII., fig. 3.) 



665. IMMERSED LEPRALIA (Lepralia immersd). Crusta- 

 ceous; cells ovate, immersed in the crust. Openings 

 roundish, with a tooth at the upper and several spines on 

 the lower margin. On shells and stones, in deep water. 

 (PI. VIII, fig. 5.) 



666. REDDISH LEPRALIA (Lepralia cocanea). Crusta- 

 ceous; cells shortly cylindrical, rough. The aperture 

 toothed on the upper margin, and with four or five long
