Fig. 66. — Anaphase groups containing thirty and thirty-one chromo- 
somes respectively. No vesicles. 
Figs. 67-69. — Chromosomes from eggs of E. acnt\is. Series C. 
Fig. 67. — Anaphase with thirty-seven (?) and thirty-five (?) chromo- 
somes. A double element is seen omitted at the equator of the spindle. 
IMany of the other chromosomes seem to be paired. 
Fig. 68. — Anaphase with four omitted chromosomes. 
Fig. 69. — Early anaphase. Some chromosomes have only just 
divided and appear to be lagging behind the rest. 
Figs. 70 and 71. — Chromosomes from eggs of E. acutus. Series C. 
Fig. 70. — Equatorial plate with thirty-five chromosomes and three 
vesicles. 
Fig. 71. — Prophase with thirty-four chromosomes and three stained 
vesicles. The large unstained vesicle is regarded as having been cut 
twice. Hence there is a total of four vesicles in this section.
