13. The eggs are deposited in capsules, normally con- 

 taining from 15 to 22 eggs. The capsules are arranged 

 in rows within a gelatinous mass, sometimes quite regu- 

 larly; the gelatinous mass is formed into a belt from 3 to 

 5 cm. wide ; the mucous flow is greater in one side of the 

 belt than in the other, so that one side of the belt is shorter 

 than the other, and the belt curves into a funnel-shaped 

 mass, the apex adhering to some sea-weed, near the sur- 

 face of the water.

 tilized; no cleavage of such eggs follows. 



15. Normally the embryo develops within two weeks.
