ZOOPHYTOLOGY. 
In the ‘ Dublin Natural History Review,’ for July, 1858, 
Professor Wyville Thomson has described several new genera 
and species of Marine Polyzoa, collected for the most part by 
Professor W. B. Harvey in the Australian seas, but with 
which, with a view to the important subject of geographical 
distribution, Professor W. Thomson has incorporated one or 
two smaller collections sent to Professor Harvey with Algz 
from various parts of the world. 
Of this valuable contribution to Zoophytology we proceed 
to give the following abstract, containing the description of 
the new genera and species established by Professor Thom- 
son; premising that the arrangement followed by him is 
pretty nearly the same as that adopted by ourselves in the 
British Museum Catalogue. 
The new species are all figured, and of them we hope 
shortly to be able also to give representations from original 
drawings from specimens kindly furnished by Professor W. 
Thomson. 
Class —POLYZOA. 
Order 1. P. INFUNDIBULATA. 
Sub-order 1. CHxrILOSTOMATA. 
Sect. 1. Articulata. 
Subsect. 1. Uniserialaria. 
1. Fam. CatENIcELLIDA, Busk. 
1. Gen. Cutenicella, Blainville. 
As usual in collections from the other side of the equator, 
the Catenicelle are prominent and abundant. Most of the 
species in the “ Rattlesnake” collection are repeated, and 
seven undescribed forms occur. One new species belongs to 
the fenestrate division ; the second differs so completely from 
every described form as scarcely to be referable to any 
of the formerly characterised groups, though occupying a 
position to a certain extent intermediate between the two
