 THE RESULTS of DEEP-SEA INVESTIGATIONS in the 



TASMAN SEA. 



I.— THE EXPEDITION of H.M.C.S. " MINER." 1 



5. — The Polyzoa. 



By C. M. Maplestone, Eltham, Vict. 



(Plates lxxv.-lxxviii.) 



I. — Introduction. 



Some time ago I received for examination from Professor W. 

 A. Has well a very interesting collection of Polyzoa which had 

 been dredged in about eighty fathoms at about twenty-two miles 

 east of Port Jackson, by H.M.C.S. " Miner." Most of the speci- 

 mens were " dead " and somewhat worn, showing, I consider, that 

 the place from which they were obtained was a resting-place for 

 an accumulation of material carried from a considerable distance 

 by ocean currents. Very few, if any, seem to have been living 

 on the spot. 



The collection consisted of some roughly-sorted specimens and 

 a small portion of unsorted material. I was doubtful when I 

 received them whether I could undertake the examination. I 

 am sorry to say that I cannot at present complete the task, but 

 I have been able to deal with the most striking forms. 



The Biporce are by far the most interesting of them, of which 

 there are six new species. A detailed description is given of 

 these, and some other new species and one new genus, below. 



The known species which I have been able to identify are as 

 follow : — 



Caberea grandis, Hincks. 



Membranipora gemmata, Waters. 

 ,, profunda, McGil. 



,, bellula, Hincks. 



Cellaria australis; McGil. 



Lunutites canaliculata, McGil.
