1. 22 species and 2-varieties of mosses are studied cytologicaly. The results obtained, the number of chromosomes and the morphology of them are given in Table 1 and Figures 1-39.
2. The same number of chromosomes has been found in the plants belonging to the same genus.
3. In almost every mosses studied have been observed two heterochromosomes; one of which has the largest volume in each chromosomeset, the other the smallest volume. The former may be denoted with Hand the later with h, as that already in the similar sense has been proposed by Tatuuo (1941) in liverworts.
