In the little knowledge we have of their € the strongest 
proofs exist of their affinity with the worms. .Lacaze-Duthiers figures 
a positive articulate and worm-like character. From the body of this 
embryo, prominent bristles project. Smitt figures the same in the 
embryo of Lepralia, wherein he describes six bristles that appear loco- 
motive; and Claparéde figures the embryo of Nerine, a worm, in which 
we find similar bristles Matias from the body. In this condi lMon it 
is interesting to note that in the winter eggs, or statoblasts, of Polyzoa 
we have a relation to Mb ecu among the lower crustacea, the 
ephippia of Daphnia, and the winter eggs of Rotifers, for example

from the sand, yet the wound was quickly healed and a new sand-tube 
promptly formed. When placed on the surface of the sand they were
