Order 8.—Alcyonaria. 
Polypes with eight fringed tentacula. Always aggregated. Never 
locomotive. 
Order 4.—Ctenophora. 
Oceanic, free-swimming, transparent, gelatinous Actinozoa, moving 
by means of vertical rows of ciliated plates. 
The author further remarked that the above classification differed 
more in appearance than in reality from the arrangements of other 
naturalists. The Hydromeduside of Vogt contained all the forms in- 
cluded among the Hydrozoa, as above defined, with the sole exception 
of the genus Lucernaria. The Acalephe of Agassiz and Milne-Edwards 
may be regarded as equivalent to the Hydromeduside of Vogt, together 
with the order Ctenophora. The slowness of zoologists to recognise the 
true affinities of the last-mentioned group offers, at present, almost the 
only obstacle to the diffusion of sound views in reference to the subjects 
discussed in the foregoing paper. 
The following antiquities were presented to the Museum :— 
By Frederick Grome, Esq.:—A curious bone pin, found in a 
field between Miltown and Newbridge, county of Kildare, with an 
iron dagger, and the skeletons of a man and horse; also two encaustic 
tiles found at Great Connell Abbey, county of Kildare. 
By Aquilla Smith, M.D.:—An impression of a seal in the muni-
