Studies in cellular slime moulds from Indian soils - III. On the occurrence of two strains ofDictyostelium mucoroides-Complex, conforming to the speciesDictyostelium sphaerocephalum (Oud.) Saccardo and March
Two strains ofDictyostelium mucoroides-complex referable to the speciesD. sphaerocephalum (Oud.) Sacc. and March. have been described for the first time from Indian soils. A larger spore size range has been observed than those of the previously recorded strains of this species. One strain seems to combine the characters ofD. sphaerocephalum andD. brevicaule Olive in having smaller sorocarps and a larger maximum spore size limit.

The morphology of the juvenile leaves of three species ofBolbitis is described, and the progression of the leaf form and venation pattern from the cotyledonary leaf to the adult condition is traced. The leaf lamina becomes bipinnate, from the obcuneate simple condition, in the successive juvenile leaves and then reverts to the simply pinnate adult form. In addition to glandular hairs of the type found on the adult leaves, the juvenile leaves bear long acicular hairs. The possible significance of these peculiarities in phyletic studies is discussed.

The influence of altitude, physical barriers, substratum, flow of water, temperature, turbidity, pH, dissolved oxygen, free carbon dioxide, alkalinity, chlorides, silicates, phosphates, nitrates, plankton, flora, food, natural enemies and bottom fauna on the distribution of the fish fauna of the Pykara and Moyar Rivers was studied. Altitude, physical barriers and temperature were the factors which substantially influenced the distribution of fishes. Altitude and temperature are interrelated.
No direct correlation could be found between other factors and distribution.
