146 A MONOGRAPH OF THE AUSTRALIAN SPONGES, 



O. Schmidt (118) published a most important paper on the 

 sponges of the Gulf of Mexico, where the views expressed by the 

 same author in his paper on the Atlantic Sponge-fauna are carried 

 out. The sponges described are throughout siliceous deep sea- 

 sponges : Lithistida? and Hexactinellida3. In the preface we find 

 some notes concerning Bowerbank, who, although being personally 

 acquainted with 0. Schmidt, seems to have remained ignorant of 

 the contents of 0. Schmidt's papers on sponges. 



Hyatt (119) describes many new American sponges, mostly 

 Ceraospongia?. 



It would lead too far to review here all the papers containing 

 descriptions of new species, suffice it to note a few of the more 

 important publications of this kind. 



The most prominent authors in this field are the following : — 

 Marenzeller (120), Carter (121), Higgin (122), Czerniavsky
