Professor of Zoology in the University of London (King's College). 



[With Four Plates.] 



Mr. Hornell's collection of Non-Calcareous Sponges contains about fifty-eight 

 species, of which I have been able to identify no fewer than forty-two with previously 

 described forms and to describe fifteen as new. Leaving out of account numerous 

 fragments which were not suificiently well-preserved for identification, the following 

 is a complete list of the species represented. It will be observed that one species 

 {Higginsia sp.) has only been generically identified, but the genus is of sufficient interest 

 to make it worth recording. 



ORDER TETRAXONIDA. 

 SUB-ORDER ASTROTETRAXONIDA. 



Family Stellettid^. 



1. Myriastra (Pilochrota) haeckeli Sollas. 



2. Jaspis reptans (Dendy). 



3. Asteropus simplex (Carter).
