In the vicinity of Kyoto City, 4 species of freshwater planarians, Dugesia japonica, Phagocata vivida, Phagocata kawakatsui and Bdellocephala brunnea, were found. D. japonica was most common in the stations both in the plain and the mountainous districts (below the altitude of about 950 m). P. vivida was rather common in the cold-water stations within the altitude range from about 120 to 950 m or more. P. kawakatsui was found only in a spring-fed stream in Kameoka City (Asahi-cho; the type locality of this species) and in a shallow well at Saga-tenryuji-chd in Kyoto City. A small population of B. brunnea was found in a large spring-fed stream at Nishioji-sichijo in Kyoto City (the southernmost locality of this species). This station is well known to biologists as the locality of the sexual race of D. japonica (the Nishioji stock). The type of the vertical distribution in the area surveyed is shown as J-JV-V (J; D japonica; V: P vivida). The 2 species of true lake-dwelling tri-clads, BdellocepEala annandalci and Dendrocoelopsis? sp. of Lake Biwa-ko, were recorded from the muddy bottom (35 to 50 m or more in depth) of the middle and northern parts of Lake Biwa-ko.

Two lake-dwelling species of paludicolen triclads from Lake Biwa-ko (Honsh, Japan) were studied taxonomically and karyologically. (1) Phagocata kawakatsui Okugawa, 1956, is an epigean species usually inhabiting shallow springs and spring-fed streams in Central Japan. In Lake Biwa-ko, animals were obtained from several bottom stations of the littoral area in the southern part of the northern basin (3\–70 m in depth). Chromosome numbers and karyotype: 2x=24 (2m+2sm+2sm+2m+2sm+2m+2sm+2m+2m+2sm+2m+2m). The first pair of metacentric chromosomes is very large in size. (2) Bdellocephala annandalei Ijima et Kaburaki, 1916, an endemic species, is distributed widely in the deep areas of the northern basin (30 to over 100 m in depth). Chromosome numbers and karyotype: 2x=28 (2m+2sm+2sm+2sm+2sm+2m+2m+2m+2m+2m+2m+2m+2m+2m) with the first pair of metacentric chromosomes very long.

The length of the telomeric DNA in nine species of planarians inhabiting Lake Baikal and one Siberian species from Baikal rivers was determined using Southern hybridization. According to preliminary estimations, it varied in the range of 25-30 kb (Rimacephalus arecepta, Rimacephalus pulvinar, Sorocelis hepatizon, Sorocelis nigrofasciata, Protocotylus sp., Baikalobia guttata, Bdellocephala baikalensis, Phagocata sibirica) and 50 kb (Baikaloplana valida, Baikalobia copulatrix). It is the first estimation of the values of telomeric region lengths for Baikal free-living flat worms.
