Introduction. 



During the past few years Mr. J. Bracebridge Wilson has, 

 by perseveringly dredging in the neighbourhood of Port Phillip, 

 accumulated a collection of sponges which already numbers 

 something like 2000 specimens, and is probably the most com- 

 plete collection ever brought together from the shores of any 

 one country. The entire collection has been generously placed 

 in my hands for investigation, and Professor McCoy has like- 

 wise kindly placed at my disposal the collection contained in 

 the National Museum at Melbourne. The task of dealing 

 with so large a mass of material is, I need hardly say, one of 

 great magnitude, and the systematic investigation must neces- 

 sarily extend over several years. The difficulty of the work, 

 so far as identification of species is concerned, has been greatly 

 lessened by the courtesy of Mr. H. J. Carter, who has gene- 

 rously sent me his own copy of his work on the Port Phillip 

 Calcispongise (1), containing a large number of unpublished 

 sketches ; and of Dr. Giinther, to whom I am deeply indebted
