PROTOZOA IN THE REPRODUCTIVE ORGAN 109 



undulating membrane will be noticed. Further degener- 

 ated forms are rounded and are with or without fiagella. 

 The undulating membrane in larger individuals, does not 

 usuallv reach the posterior end of body. 



2. Stained specimens. The general morphological fea- 

 ture (Fig. 29, 3, 4) is similar to that of T. hominis (p. 38). 

 But the costa is less conspicuous in the present form. The 

 nucleus is p\ riform or oval. The cvtoplasm contains bac- 

 teria and numerous granules. 



The detection of the flagellate can be done easily by 

 examining fresh smears of vaginal secretions in bright and 

 dark field under the microscope. For permanent prepara- 

 tion, use either Heidenhain's iron haematoxylin in the way 

 the faecal smears are handled (p. 59) or Giemsa's stain as 

 given for blood-inhabiting protozoa (p. 99).
