R. W. H. ROW—REPORT ON THE SPONGES: CALCAREA. 183. 
The collection is extremely interesting owing to its strikingly intermediate 
character between the faunas of the Mediterranean and Atlantic on the one 
hand, and of the Indian Ocean on the other, as is shown by the subjoined 
table, in which it should be noted that the coasts mentioned always include 
the islands near them.

The preservation of the specimens is unfortunately not sufficiently good 
to render them available for histological study. 
Numbers in parentheses refer to the literature quoted at the end of the 
paper. 
I take this opportunity of expressing my gratitude to Professor Dendy, 
by whose kindness I obtained the collection for examination, and whose 
suggestions and advice have been invaluable to me throughout the work, 
which has been carried out in the Zoological Laboratory at King’s College 
(University of London).
