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 haying 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.
