CLASS ANNELIDA. 
Aricia, Sav., want both teeth and tentacula. Their body, 
which is elongated, supports upon the back two ranges of 
lamellated cirrhi, and their anterior feet are furnished with 
denticulated crests, which are not found on the other feet.

The Lumbricus Armiger , Mull., Zool., Dan. pi. xxii. f. 4 and 
5, of which, without having seen it, M. de Blainville proposes 
to form a genus under the name of Scolople, appears to 
want both teeth and tentacula, and to have simple small 
bundles of short bristles on its first segments, and a bifid 
wart, a small bristle, and abranchial lamina, long and pointed, 
on the others. 
Our coasts of the Atlantic possess some species of many 
of these genera. 
Hesione have the body short, tolerably thick, and com- 
posed of few and indistinct rings ; a very long cirrhus, which 
probably performs the function of gills, occupies the upper 
part of each foot, which also has another inferior one, and a 
bundle of bristles. Their proboscis is large, and without 
jaws or tentacula. We have some from the Mediterranean,

Ophelina, Sav . 
The body thick and short, with feebly-marked rings, and 
scarcely perceptible bristles ; some long cirrhi, serving as 
gills on the two thirds of its length. The mouth contains, at 
the palate, a denticulated crest; its lips are surrounded with 
tentacula, of which the upper two are larger than the others.

come the Nereis prismatica and bifrons , Fabric. Soc. d’Hist.
