144 SIDNEY F. HARMER. 
Fic. 35.—Longitudinal section of the embryophore, with actively dividing 
primary embryo. The brown body is not seen in this section, but would have 
come at the upper end of the figure. From a colony ‘53 mm. long. 
Fic. 36.—Longitudinal section of a young embryophore belonging to a 
second or later generation. The brown body is conspicuously larger than that 
of the corresponding stage (Fig. 28) of the first generation. The embryophore 
lies in a space which is clearly a zoecium. (Diameter of the colony 2°20 mm. 
Length of the embryo plus the embryophore 167°2 ». Longest diameter of 
the brown body 83°6 w; of the embryo, 86 zp.) 
Fie. 37.—Showing the fission of a young secondary embryo, belong- 
ing to the first brood. From a colony ‘93 mm. long and ‘88 mm. broad, 
similar to that-shown in Fig. 11. The longest measurement of the dividing 
embryo is 56 p.
