✦ Synopsis

G l y p h i d d m nnnandalei MICHAELSON exhibits a pronounced breeding period extending from

September t o Xovember. Breeding individuals achieve their maximum frequency in September, when 50 per cent of the whole population was with fully developed clitellum. Studies 011 the physical and chemical conditions of the habitat revealed that breeding in this worm depends on the monsoon of the area creating optimum conditions for the life and activities of the organism.

in February to 7.45 in December and organic content of soil from 6.8 (I ,, in February-March to 13 ",,, in Koveniber. The organic content of the soil maintained a high level during the breeding period, reaching its maxinium of 12 "0 by Eovcniber.
