 probable that this is the case for Phorouis architecta because

 University which are fifteen mouths old. 



Durin^-, one low tide in the sunaiicr ana autumn, I found it an 

 easy jnaiter to collect from 100 to 150 specimens of Phoronis 

 architecta. About one half of these vvoula usually be with male 

 reproductive organs and the rest with female reproauctive ori_,ans. 

 The Phoronis were j. lace a in glass crys talliiiing dishes ana af- 

 ter about twenty-four hours many of the indiviauals began to 

 lay, usually at night, but the eggs were not retained among 

 the tentacles in a mass as describea by most investigators , but 

 were sv/ept gently away from the lophophoral crov;n by the cilia- 

 ticn on the tentacles axid on the anal region so that they set- 

 tled near by on the bottom of the dish. Sometimes, iiowever, 

 the newly laid eggs were carried up ana dovm the tentacles in 

 currents caused by the cilia ar.a occasionally a. few eggs v.'ere 

 found groi'fed near the tips of the tentacles, bein.v hela there 

 loosely by a sraal] quantity o-f" mucus-like material. At no 

 time, however, were eggs aixi larvae ag,,regatea in definite mas- 

 ses as aescribed by Ikeda (9) nor were they brocdea airong the 

 tentacles as Ma^teman (IG)has observed in tne cas« of Phoronis
