438 POLYPI. 
Amatia, Lamour.—Serriauaria, Lam., 
Where they are united, in certain places, like the pipes of an organ *, 
We might distinguish those species in which the cells, thus dis- 
posed, form a spiral line round the stem. 
ANTENNULARIA, Lam.—CaAuuiAnyra, Lamour, 
Where the cells form horizontal rings round the stem f. 
Thus the name of 
SERTULARIA proper, 
Becomes restricted to those in which the cells are placed on: both 
sides of the stem, either oppositely {, or alternately §. The first 
are even again separated by Lamouroux under the name of Dyna- 
menes. 
Where the cells are extremely small we have his genus THOEA ||. 
FAMILY II. 
CELLULARII (a). 
Where each Polypus is adherent in a corneous or calcareous cell 
with thin parietes and only communicates with the others by an ex- 
tremely tenuous external tunic or by the minute pores which traverse 
the parietes of the cells. These Polypi bear a general resemblance - 
to the Hydre. 
CrELLuLarra, Lin. 
Where these cells are so arranged as to form branching stems in the 
manner of the Sertulariz, but without a tube of communication in 
the axis. ‘Their substance also is more calcareous.
