Abstract
WHAT must be one of the most remarkable spermatozoa of Insecta is that of Lepisma, as reported by Bowen1, Nath and Bhatia2, and Nath3. In Fig. 7, this spermatozoon is shown with a centriole (C) as its anterior end, connected by a flagellum (F), across the nucleus (N) to another body (A) said to be the acrosome, from which passes back the tail of the spermatozoon. With the acrosome in such a peculiar position, it is difficult to understand how this spermatozoon gets into the egg, always assuming that the acrosome of Lepisma takes the usual part in this process. It would seem also that the centriole lies in an unsheltered position, assuming again that this centriole is necessary for initiating the fertilization spindle of Lepisma.
