G ^is, i n particular situations, is very common, as on the

I’ll* ^ u ^ es are simple from the roots to the terminations, 
3ti(j 'eight of the tubes varies from two to fourteen inches,

Pfo f a ^ e °f being withdrawn into the tubes. The mouth is 
led Uce ^ into a conical elevation, and around is a circle of 
tej). le ntacula ; inferior to this circle is another in which the 
are much longer than in the one above. Below this 
are P r0( ^ ucet f the reproductive gemmulcs. The
