In a series of papers which appeared in the ' Quarterly 

 Journal of Microscopical Science ' some years since, Mr. 

 Busk published a list of Madeiran Polyzoa which he had 

 received from Mr. Johnson, and described a considerable 

 number of new forms. About fifty species were recorded as 

 occurring off the island, of which eighteen (or about a third) 

 are also British. In the present paper twenty-five species are 

 added to the Polyzoan fauna of Madeira, raising the whole 

 number to about seventy-five; and of these seventeen arc 

 British ; so that thirty-five species, or nearly one half of 

 those recorded in these papers from the island, are common to 

 it and our own coasts*. Of these, eight (or about a quarter) 

 are confined to the south-western or south-eastern (Hastings) 

 portions of the English coast, whilst about a third have been 

 found in the Crag. 



* A large proportion of these have heeii found in the Mediter- 

 ranean.
