in the following mnnner, taking the subgeneric characters partly from the 
nematotheca,” and partly from the yunocladia ” ; —

The total number of species described is 66 (14 ‘‘ incertee sedis ”). The 
new terms proposed are: — nematocalyces,:=ii\ie chitinous investment of the 
lateral (paired) nematophora, those of the others (mesial, unpaired) being 
termed nematothecce j yonocladia, those branches of the polyparium to which 
gonangia are attached j nematocladia, the lateral branches of the gonocladia, 
set with nematothecas only.
