TH. MORTEN'SF.N : 



Altogether the development of no less than 16 species of Echi- 

 noderms has been studied, more or less completely, during my three 

 months' stay at the marine laboratory at Misaki. 



In conclusion I beg to tender herewith my most sincere thanks 

 to my Japanese colleagues, especially to Professor Ijima, for the very 

 kind reception given to me.
