extensive sub-kingdom, Coelenterata. These two classes are the Hydrozoa 
and the Actinozoa. That the Lucernaria is to he placed in the latter seems 
more than doubtful. Those who associate it with the Actinia do not 
appear to be at all familiar with its anatomy. More wisely, we think, 
has Mr. Huxley placed it among the Hydrozoa, and made it the type of 
an extensive family, containing the Hydra tuba , and such of the discoid 
Medusae whose direct development from ova seems established, e. g., 
Eginopsis. Such appears to be its true position. 
Dr. E. Percival Wright did not coincide with Professor J. Reay Greene's 
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. 
Dr. E. Percival Wright, Director of the University Museum, stated 
that for the last few months he had been engaged in arranging the col¬ 
lections made by Professor Harvey in Australia, Tasmania, Hew Zealand, 
and Eiji. It would, of course, be a work of some years before the 
whole 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 Shells. Prom 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 Professor Wyville Thomson— 
ON NEW GENERA AND SPECIES OF POLYZOA IN THE COLLECTION OF PROFESSOR 
W. H. HARVEY, OF TRINITY COLLEGE, DUBLIN (WITH FIVE PLATES). 
Part I. 
Dr. Harvey 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, 
and still more for his friendly MSS., assistance, and counsel. Some ad-
