cording to others for the issue of the eggs. There are no feet, 
except in five short furrows, which form a star around the 
mouth. (Ast. ophiwra, Lin., &c.) 
The GORGONOCEPHALA, Leach, named Euryale, by M. 
de Lamarck, are those in which the radii are divided into a 
double point. There are some in which this division com- 
mences from the base of the radii, and which present the 
appearance of a parcel of serpents. They have been vulgarly 
named heads of Medusa. The base of each ray has two 
penetrating holes. (Asterias caput Meduse, &c.) 
But there are also some in which the division commences 
only at the end of the ray, and is but little repeated. (Huryale 
palmiferum, Lam.) 
We should still separate from the other asteriz 
The ALEcTO of Leach, which M. de Lamarck calls Coma- 
tula. ‘They have five large articulated radii, divided each 
into two or three, which support two ranges of articulated 
filaments. These five radii are attached to a stony disk 
which again supports, on the side opposite to the mouth, one, 
two, or three ranges of other articulated filaments without 
branches, shorter and thinner than the large radii, and which, 
it is said, enable them to hook themselves to bodies. The 
sac which contains the viscera is at the centre of the large 
radii, opened by a star-formed mouth, and another tubular 
orifice, which may be the anus. (Asterias multiradiata, &c.) 
It is near the comatule that we should place 
ENCRINUS, Guett., 
Which may be defined to be comatule, with a disk prolonged 
into a stem divided into a great number of articulations. 
Their branches themselves are articulated, and divided into 
pairs of branches, supporting a range of filaments, all articu- 
lated, and the stem itself supports some smaller ones, at
