THE SPONGES. 



INTRODUCTION. 



The collection of sponges with which the following report deals has been 

 found to include forty-seven species and subspecies. Of these, twenty-six, 

 representing thirteen genera, fall in the Hexactinellida, seven, representing 

 three genera, fall in the Tetractinellida, and fourteen, representing nine 

 genera, fall in the Monaxonida. No calcareous or horny sponges and no 

 Lithistids were taken. As was to have been expected, since the expedi- 

 tion was made in unexplored waters, a very large percentage of the forms 

 (thirty-three species and subspecies) prove new to science.
