PORIFERA. 



The only local List of Sponges is one recently published by Mr. E. Parfitt, 

 " On the Marine and Freshwater Sponges of Devonshire " (Trans. Devonshire 

 Association for the Advancement of Science, Literature, and Art, 1868) ; it 

 includes forty-nine marine species, while the Shetland species observed by us 

 are eighty- three. Only eighteen of these species are as yet known to be 

 common to these two extremities of our islands.

Species added to the British Fauna during the recent Dredging. 

 The new species which have during the past six years been discovered in 

 Shetland have from time to time been published through various channels, a 

 large proportion of them having been placed in the hands of those naturalists 

 who were engaged in bringing out works on the several branches of marine 

 zoology. The following list of 156 species is therefore given here in order to 

 show at a glance the additions to our fauna which have directly resulted from 

 the investigations of the Dredging Committee.
