242 Myr. H. J. Carter’s Contributions to our 
tion of the elastic tissue of the Spongida, which, although 
principally developed in the Carnosa, is so widely distributed 
throughout the class, that it may be considered one of the 
constituent elements of the Spongida, and therefore deserving 
of that special attention which hitherto it has not had. 
Finally, I propose adding some observations on other sponges 
which seem to claim admission into the Carnosa, ending with 
a notice of Dr. Oscar Schmidt’s genus Cellulophana. 
Since the Ray Society published the late Dr. Bowerbank’s 
work on the British sponges, entitled ‘ A Monograph of the 
British Spongiade’ (Nos. 6 and 21 respectively), which is 
chiefly confined to the species growing on the shores and com- 
paratively shallow depths of the submarine bank immediately 
round the British Isles, not only more species from this 
locality have been discovered, but the “ dredgings” of 
H.M.S. ‘ Porcupine,’ having extended a little beyond the 
border of the bank into the “deep sea” of the Atlantic
