ZOOPHYTOLOGY. 
For the interesting additions to the Zoophytological 
Fauna of Madeira, contained in the following list, we have been 
indebted to Mr. J. Yates Johnson, so well known as an 
assiduous cultivator of the natural history of that island, 
and more especially of its marine productions. It is needless 
to insist upon the importance of contributions from such a 
locality towards a more complete knowledge than we as yet 
possess of the geographical disposition of species; but the 
consideration simply of such a short list as the present 
suffices to indicate that, so far as its Zoophytology is con- 
cerned, Madeira forms a connecting link between the Medi- 
terranean, on the one hand, and with the Western and 
astern shores of Africa and of South America respectively, 
on the other ; connected with the latter, perhaps, through the 
intervention of the Gulf-weed. 
The number of species comprised in the collection is about 
twenty-four, of which twenty belong to the Polyzoa, and four 
to the class of Sertularian Hydrozoa. 
The Polyzoa are arranged in the following families, with the 
characters given in the ‘ B. M. Cat. ’ 
. Scrupariade. 
. Salicornariade. 
. Bicellariadee. 
. Membraniporide. 
. Celleporide. 
Selenariadee. 
. Idmoneade. 
. Crisiade.
