Notes

Morphological form variation in a loricate rotifer, Keratella tropica Apstein is described. Form variation in this rotifer involves appearance and development of the left postero-lateral spine. The right postero-lateral spine varies, too. It increases with increasing length of lorica and left postero-lateral spine. Three morphological forms, viz. reducta, asymmetrica and heterospina are recognized.
