interval between them. Be- 
tween the cells there is a series 
of minute tubular or tooth-like 
cells, visible only with a high 
magnifier. The ovarian vesicles 
are produced in summer : they 
are stalked, shaped like a pear 
or vase, solitary, scattered, and 
originating always at the base of 
a polype cell. From the interme- 
diate cellules, particularly from 
the one next the polype-cell, 
there often grows up a small 
trumpet-like tube ; and I have 
seen, in one specimen, all the 
ends of the branches terminated 
by four of these tubes diverg- 
ing in pairs.-— To this very distinct and elegant species I have taken 
the liberty of assigning the Christian name of the lady to whom 
this work is indebted for nearly all its illustrations.
