TheCymbopogon species under investigation have been placed under three series and studied for their distribution and nature of endemism. Polyploid species have been recorded in the areas where the members of two or all the three series meet together.
pp 9-12 January 1970
ACymbopogon collected from Ladakh has been described and given the status of a new speciesC. ladakhensis.

The study of the protozoan fauna of insects revealed interesting flagellates belonging to the genusHexamastix. Hexamastix periplanetae n.sp. is found inhabiting the rectum ofPeriplaneta americana, andH. singhi n. sp. is from the rectal contents of the mole-cricket,Gryllotalpa africana. They differ in various characteristics from the other species which were described from the insects.

A new histozoic species of Myxosporidia,Myxosoma intestinalis inhabiting the gut epithelium ofMugil waigensis Quoy and Gaimard is described. This is the first record of a species ofMyxosoma from an Indian fish and also a first record of a myxosporidian fromMugil waigensis.

Experiments were conducted to find out the number of inoculations on rye spikes by needle board puncture method in relation to the yield of ergot sclerotia. It was found that the increase in number of inoculations increased the yield of ergot sclerotia upto two inoculations and the increase in yield of ergot sclerotia in plots inoculated three times, was, however, very little and the yield decreased in plots which were inoculated four times.

Investigation carried out on the effect of different concentrations of the inoculum of the ergot fungus,Claviceps purpurea (Fr.) Tul., in relation to the yield of ergot sclerotia indicated that the increase in concentration of the inoculum increased the yield of ergot sclerotia upto the D2 concentration (3200 spores/ml.). Further increase in concentration of the inoculum beyond D2 (3200 spores/ml.) gave no significant increase in the yield of ergot sclerotia.

The structure of the tongue of birds frequently gives some clue to the principal diet and manner of feeding of the species. The tongue is suitably modified for this purpose. A study of anatomy of the tongue of some birds was undertaken to find out the advantageous modifications of the hyoid apparatus and the different sets of the muscles which bring about the movement of the tongue.
