C, Mallomonas plcesslii. (From Dofiein after Klebs.) The flagella are always inserted apically and are one or two in number, the number and relative sizes determining some of the families. The monads are comparatively simple in structure and the body is usually regular and without dor so-ventral differentia- tion. The pellicle is usually delicate and inconspicuous but may be heavy and provided with keels, ridges, flanges, etc., or covered by fine silicious plates as in Mallomonas (Fig. 125). Cups and houses of cellulose, often colored by iron oxide, are abundant and frequently.
