790 NEW GENERA OF MONAXONID SPONGES, 



In conveying the impression that the aeanthostyli of /. char- 

 tacea occur as eehinating spicules, and that spongin is developed 

 in connection with the skeleton-reticulation in considerable 

 amount the original description of the species, — as I have already 

 indicated .(6, p. 208), — is in error.
