Notes
A bloom of Euglena was observed at the surface of Dal Lake, Kashmir, in the last week of June, 1991. The species exhibited a circadian colour change, from green at dawn to blood-red during the day and again green at dusk. The present new species is, therefore, named Euglena shafiqii. It is distinguished from the cogenus by the structure and occurrence of Z-tubules, chromatophores, nucleus shape and by a coloured pulsating structure at the posterior end. A stress induced transformation from an elongated egg to a round shape is also peculiar. The light absorption spectra of the pigment showed ramuda maxima at 416, 441, 467 and 485 nm. The red bloom was found in the part of the lake basins which receives waste effluents.
