Art. XXI. — Report of the Port Pliillip Biological SuvveAj 

 Committee, 1892. 



Your Committee regret that tliere are no results to rej)ort 

 as received from the specialists in Eui'ope to whom material 

 was forwarded, though we have information that the work 

 is in hand. During the course of next year, Professor 

 Spencer, who is on the Committee, is visiting Europe, and 

 hopes to arrange for an early publication of the descriptions. 



Professor Tate, of Adelaide, has returned the specimens of 

 the Nudibranch Mollusca, as he finds himself unable, through 

 pressure of other duties, to undertake their determination. 



Dr. Dendy has continued liis studies on the Sponges, and 

 has worked out the classification and much of the detailed 

 anatomy of the Calcarea Heterocoela. He is publishing a 

 Synopsis of this work in the Proceedings of our Society, and 

 anatomical accounts in the European journals. 



Your Committee have incurred no expenses during the 

 year. 



A. H. S. Lucas, Hon. Secretary.
