merous tentacula united in bundles are arranged round its edges. 
Between the mouth and these same edges are eight organs resem- 
bling czca, proceeding from the stomach and containing a red and 
granulated substance. In the 
S. guadricornis, Miill., Zool. Dan., XX XIX, 1, 6, the edge 
is divided into four forked branches, each of which bears two 
groups of tentacula. In the 
L. auricula, Ibid., CLII, the eight groups are equally distri- 
buted round an octagonal margin(1). 
ORDER II. 
GELATINOSI. 
The gelatinous Polypi, unlike the preceding ones, are not 
invested with a firm envelope, neither is there a ligneous, 
fleshy, nor corneous axis in the interior of their mass. Their 
body is gelatinous and more or less conical ; its cavity sup- 
plies the want of a stomach. 
Hypra, Lin. 
Of all the animals of this class, these are reduced to the greatest 
degree of simplicity. A little gelatinous horn, whose edges are pro- 
vided with filaments that act as tentacula, constitutes their whole 
apparent organization. The microscope discovers nothing in their
