INTRODUCTION 
The Stomatopoda has long been known to possess spermatozoa 
of a peculiar appearance, which differ widely not only from the 
ordinary filiform ones, but also from those usually found in the 
Decapoda. However, apart from a few rather old works, we 
have practically none in literature dealing with the morphology 
and genesis of the spermatozoon. At the suggestion of Doctor 
Yatsu, I undertook the study, the result of which has formed 
the data presented in this report. In pursuing the study as 
well as in working out the manuscript, I am deeply indebted to 
Doctor Yatsu.
