PLATE 6 
EXPLANATION OF FIGURES 
67 Embryo turned slightly to the left to show the anterior and the posterior 
ends; the embryo at this stage begins to rotate within the egg membrane. 
68 The same as the preceding from the ventral pole, turned a little to the left. 
69 Embryo viewed from the right side; condition before the posterior end 
becomes drawn out or pointed. 
70 Embryo from the upper pole; shows compressed condition of the two 
ends; at this stage the embryo rotates very rapidly. 
71 Embryo viewed from the right side; the teloblasts are partially visible 
at the posterior end; the tapering of the posterior end is well marked. 
72 Embryo to show the overlapping of the ends; indications of segments are 
visible anteriorly; the stomadaeum is distinct. 
73 Unusual condition, where the two ends remain in immediate contact 
until after the form of the worm is distinct; this occurs in eggs with an unusually 
large cocoon. 
74-6 Different stages in the final growth of the embryo. 
77 Condition of embryo at the time of emergence from the egg.
