Some years ago we investigated the Thecamoebous Rhizopods in a number of dried moss samples obtained by purchase from several localities in Europe. The results of this investigation, partly unpublished yet, were relatively satisfactory and induced us (in 1938/'39) to treat some moss samples from outside Europe in the same manner. They were collected in New Zealand (19), Siberia (8), China (1), Africa (1), South America (11) and North America (17), in all 57 localities. Some of the samples proved rather rich in remains of Rhizopods; these we studied more thoroughly and determined the relative frequency of the different species occurring in it. This frequency we expressed in numbers varying from 1 to 6, 1 meaning very rare, 6 very common. Of the other samples we observed only a few preparations and noted the species, occurring in it, which were also entered in the general survey of the species.
