On the occasion of a visit to the Indian Museum, Calcutta, I 

 was kindly permitted by Dr. Annandale^ the Superintendent of the 

 Museum, to inspect the collection of vSponges. Among the treasures 

 obtained from the Indian Ocean by the "Investigator," were 

 several dictyonine sponges of very elegant and remarkable form, all 

 belonging to a species which had not been described before. For 

 reasons stated below^ I consider the species to come under Eur etc, 

 despite the fact that there is no " beautiful network " of anasto- 

 mosing tubes, but simply a vertical hollow stem with hollow- 

 separate lamellae. Dr. Annandale entrusted the material to me 

 for description, and I propose to name the new species Eurete 

 annandalei. •

 pair forming angles of 50"^ and 130° with the pair immediately above 

 and below. Lamellate branches tubular at place of origin, then 

 explanate and obcordate, and with thin margin ; with a well- 

 delaned round orifice on Lhe upper and under surface of each
