267 young from 400 adults taken haphazard. 



The size of the young was found to be independent of the 

 size of the parent. An eight-millimeter young is as likely to 

 be in a fourteen-millimeter parent as in one of eighteen milli- 

 meters length. The majority of the above contained two young, 

 one in each inner gill. A few contained four. 



Similar data were taken from Calyculina which were killed 

 in June 1913.

The great variation in the number of young is probably due 

 to the fact that some had already emerged from the parent 

 pouch. I have no records which include totals of young of all 

 stages. In one specimen I was able to count twenty-four.
