almost in juxtaposition, as the Sponges and the Gorgonise. The 
merits of Lamouroux have always appeared to me to have been 
much overrated : it is a very easy matter, by arbitrarily fixing 
on this or that character, to set in order any given number of 
objects in any pattern we may choose, and Lamouroux had no 
higher notion of the character of a systematist than this, and 
acted accordingly. It is very true that he named and distinguish- 
ed many genera, but who, on critically examining these genera, 
will deny that he proceeded without caution and without judg- 
ment, — determined apparently to make as many as could be 
made that his successors might be spared the unprofitable task 
of coining and inventing names ! *

Class POLYPI. 
Order I. P. ciliati. 
Polypes without tentacula, but having- near the mouth, or at its ori- 
fice, vibratile cilise or ciliated and rotatory organs which agitate 
or whirl the water. 
I. Section — Vibratiles — -Rattulus, Trichocerca, Vaginicola. 
II. Section. — Rotiferes. — Folliculina, Brachionus, Furcularia, 
Urceolaria, Vorticella, Tubicolaria. 
Order II. P. denudati. 
Polypes with tentacula, without an envelope or polypidom, and fixed 
either permanently or spontaneously. 
Hydra — Coryne — Pedicellaria — Zoantha. 
Order III. P. vaginati. 
Polypes with tentacula, invariably fixed in an inorganic polypidom 
which envelopes them ; and forming, in general, compound animals. 
* Polypidoms of homogeneous composition. 
I. Section. Polypiers fluviatiles. — DifHugia, Cristatella, 
Spongilla, Alcyonella. 
* Blainville in criticising Lamouroux’s latest work, says— “ Nous nous bor- 
nerons a dire que Lamouroux a encore considerablement augmente le nombre 
des genres, surtout parmi les polypiers pierreux, pour y placer un grand nombre 
de corps organises fossiles, trouves dans le calcaire a polypiers de Caen, et que 
malheureusement la plupart de ces genres sont mal caracterises, ce dont je me 
suis assure directement sur les objets memes qui ont servi a ses observations.”
