of the embryos would be interesting to dwell upon ; 

 but, after all, these changes are wholly technical 

 and needless to recount for the purpose of this 

 paper. Suffice it to say that I watched my new- 

 found fry with unremitting attention for an entire 

 month. During this time, the major alterations 

 were chiefly represented by a gradual growth of the 

 embryos which after the first week became more 

 adult-like each succeeding day. Development was 

 direct, there being no "veliger," or free-swimming, 

 stage such as marks the metamorphosis of the clam 

 and other familiar mollusks. At the end of this 

 period, the young, now about an eighth of an inch 

 long, escaped from the disintegrating capsules; 

 and I then decided to return them to the sea. 



My decision was prompted partly by expedi- 

 ency. Obviously it was impossible to keep alive 

 for long in the restricted quarters of the laboratory
