The Sponges wlnch Prof. Weber has been kind enough to send 

 me for examination belong to three well-defined species, two re- 

 presenting tlie geniis Spongüla (sensu lato), the tliird Ephydaiia. 

 Owing to tlie kindness of Mr. R. Kikkpatrick of tlie British Museum, 

 and Dr. W. Michaelsen of the Hamburg Natural History Museum, 

 I have been able to conipare them with pieces of the types of most 

 of the species as yet recorded from the continent of Africa, while 

 the large collection of Asiatic and European Spongillinae in the 

 Indian Museum has much facilitated my task.
