G. V. Koch (13) confirms the derivation of the spermatozoa from the 
ectoderm in Hydractinia echinata and Tubularia larynx, and that of the 
ova from the endoderm in the last named species and in Coryne fruticosa. 
He further describes the male gemmules in Eudendrium ramosum. Also 
in Tiarella (24), the spermatozoa originate from the ectoderm. On the 
other hand, Allman n (2) was unable to confirm this origin in Myrio- 
thela, where, according to his observations, both sexual products
