This fringe may consist of a single row of processes, known as teeth, as in Fig. 31, or of a double row as in Fig. 43. In the latter case the entire fringe is still the peristome, but the term is also applied in a particular sense to the outer row; the outer row is often spoken of as the exostome {b), and the inner as the endostome {c). The inner row consists of as many projections as the outer, but alternating with them; these are known as processes or segments ((). Between the segments there are often one or more slender hair- like processes known as cilia. (Fig. 43, d; fig. 36, c.) Moss peristomes, viewed with a compound microscope, are among the most beautiful of natural ob- jects. They are not composed of cells (except in the Polytrichaceic and a few other small families), but of thickened cell walls. The cross markings on the teeth, segments, and cilia are the lines of junction of the transverse cell walls with the longitudinal cell walls forming the peristome. The.
