FURTHER OBSERVATIONS ON (LEGAL PARASITES OF FOWLS. 81 
Figs. 49-52. — Doubtful dividing forms Trichomonas Eberthi, 
perhaps really early stages of conjugation. 
Figs. 53-63. — Trichomastix gallinarum. 
Figs. 53, 54. — Active elongate form, Tricliomastix gallinarum. 
Fig. 55. — Active form, Tricliomastix gallinarum. 
Fig. 56. — Active rounded form, showing chromatic line. 
Fig. 57. — First stage in division of the active form. 
Fig. 58. — Later stage in division. 
Fig. 59. — Later stage of division, showing the outgrowth of a new 
flagellum in each of the daughter individuals. 
Fig. 60. — Still later stage. 
Fig. 61. — Later stage, in which the chromatic band between the 
blepharoplasts has disappeared, and the fourth flagellum has been 
added. 
Fig. 62. — Last stage in division. 
Fig. 63. — Trichomastix gallinarum, with only three free 
flagella. 
PLATE 14. 
Figs. 64-72. — Trichomastix gallinarum. 
Fig. 64. — Resting aflagellate forms of Trichomastix gallinarum. 
Fig. 65. — Dividing resting forms. 
Fig. 66. — T richomastix gallinaru m. Possibly further stage 
in the outgrowth of flagella in an individual, resulting from the division 
of a resting form. 
Fig. 67-71. — Possibly stages in the development of flagella on 
resting individuals of T r i c h o m a s t i x g al 1 i n a r u m . 
Fig. 72. — Possibly a stage in conjugation.
