Abstract / Notes
Miscellaneous notes, based on field observations and on specimens kept in the laboratory. Most of the data confirm previous observations of other authors. Land planarians remain hidden during the day in humid, but not wet, refuges. They are most easily found, in Brazil, during the dry or winter season, from April to September. In fallen logs they are often found in great numbers inside galleries bored by insect larvae. Types of creeping motion are described. Observations on the food of various spp. are given. Specimens of several spp. of Geoplana have been kept alive in the laboratory. Their behavior, feeding, etc., and manner of catching their prey, are described. A table is given showing the number of days it took egg capsules to burst, for 8 spp., and the number of young liberated from 1 to 10, varying within a single sp.
