reasons for supposing the identity of the three mentioned species of Lu- 

 cernaria ; nor did he think that by allowing their specific distinctness 

 he acknowledged that of the young form described. 



De. E. Pebcival Weight, Director of the University Museum, stated 

 that for the last few months ho had been engaged in arranging the col- 

 lections made by Professor Harvey in Australia, Tasmania, New Zealand, 

 and Fiji. It would, of course, be a work of some years before the 

 wholo of these collections could be classified and named ; but Mr. Bower- 

 bank had kindly undertaken the Sponges ; Professor Kinahan the Crus- 

 tacea ; Professor J. Reay Greene the Echinoderms ; Professor Wyville 

 Thomson the Hydroid Zoophytes and the Polyzoa ; while he intended 

 to devote himself more especially to the Mollusca. From time to time 

 papers on portions of these subjects would be submitted to the Associ- 

 ation, and all new species would be illustrated by figures. The first 

 contribution he had much pleasure in bringing before the Members this 

 evening, namely, that of Pbofessob "Wyville Thomson — 



ON NEW GENEBA AND SPECIES OF TOLTZOA FBOM THE COLLECTION OF PBOFESSOE 

 W. H. HAEVEY, TRINITY COLLEGE, DUBLIN (WITH FIVE PLATES). 



Part I. 



De. Haevey has kindly given me an opportunity of examining a quan- 

 tity of Marine Polyzoa and Hydroid Zoophytes, principally the " refuse' ' 

 of the magnificent series of Algse lately collected by him on the southern 

 and western coasts of Australia. Though occupying this undignified po- 

 sition, the collection of Zoophytes is an extremely valuable one, the 

 largest probably, with one exception, that of the energetic " Rattle- 

 snake" naturalists, which has ever been brought to Europe from the 

 Australian seas. 



This first communication consists of an enumeration of the species 

 belonging to the first six families of the Cheilostomatous sub-order of 

 Polyzoa. 



I have few authorities to quote and to acknowledge. Mr. Busk's 

 admirable Catalogue of the Polyzoa in the British Museum has been my 

 guide throughout I have almost entirely adopted his arrangement, 

 with full concurrence in his views of grouping into families and genera. 

 I take this opportunity of thanking him most sincerely for his volume,
