Heteronereids ofPlatynereis sp. swarm in the Madras Harbour during the new moon in the months of March, June and September. An interval of three lunar months is observed between successive swarms. Swarming takes place in the night, between 7 and 10p.m. corresponding to the period of maximum high tide; it may occur on the new moon night as well as on one night previous or after. The Heteronereids are described; they appear to be different from the species ofPlatynereis already known from. India. The behaviour of the worms during swarming, swarming periods and the records of observations are given in detail. The periodicity observed in this species is compared with other known instances, and the question of lunar periodicity in reproduction is discussed.

The paper gives an account of a new type of orthorhombic pyroxene recently discovered in the biotite-cordierite-hypersthene granulites occurring near the village Bidaloti in Mysore. From a detailed study of this mineral from the physical, chemical, and optical points of view, it has been shown that this orthopyroxene has a distinct individuality of its own, distinct from the known members of the enstatite-hypersthene series, and must therefore be recognised as a new mineral. It has also been shown that this pyroxene is of unusual origin, being derived from cordierite. The authors propose to call this new mineralBidalotite after the village near which it was first found.

The present investigations show that the soil fungi are almost cosmopolitan. If detailed work is pursued, no doubt practically all the genera and many of the species reported from Europe and America could be found. Regarding the total number of the organisms, it has been found that the temperature plays a very important part as also the moisture contents of the soil.Aspergilli andPenicillii occur in the largest number in the soil and either the former or the latter will predominate depending upon whether the temperature is high or low.
About twenty species of fungi have been recorded by the author. Of these some are new records.
