ANNELIDES. 
Pleione, Sav. {Amphinome, Blainv.), which, with the same tentacles, have crest-like gills. These also are from 
the East Indies, and attain a great size. 
To these may be added Euphrosine, Sav., which has but one 
tentacle to the head, together with arbuscular gills, very 
much developed and complicated ; and to which the genus 
Anisteria, Sav., established on a mutilated individual, should 
probably be approximated ; and, lastly, 
Hipponoe, Audouin & Edwards, which, devoid of caruncle, 
has only one cirrhus and packet of bristles to each foot. There 
is one at Port Jackson, H. Gaudichaudii, Aud. & Ed. 
Eunice, Cuv. — 
Fisr. 203.-Euphrosine laxxreata. Hkcwise fuTllislied with tuft-likC gills, but the trunk 
is formidably armed with three pairs of dilFerently-forraed horny jaws ; each of their feet has two 
cirrhi and a bundle of bristles ; and there are five tentacles upon the head above the mouth and two 
on the neck. Some species only exhibit two small eyes. M. Savigny’s family of Eunices is constituted 
by this division, and the particular genus is termed by him Leodice. 
A species, from one to four feet in length, inhabits the sea around the Antilles (E. gigantea, Cuv.), which is the 
largest Annelide known. Some upon our coasts are much smaller. 
M. Savigny distinguishes by the name of MarpMsia certain species, otherwise very similar, which have no 
nuchal tentacles, and the upper cirrhus of which is very short, as Nereis sanguinea, Montagu. An allied species 
{N. tubicola, Muller), inhabits a horny tube. 
After these genera with complex branchiae, are placed those in which the organs adverted to are 
reduced to simple laminae, or even to slight tubercles, or which, lastly, are represented only by the 
cirrhi. Some of them resemble Eunice by the powerful armature of the trunk, and by their antennae 
of unequal number. Such are 
Lycidice, Sav., — 
Which, together with the jaws of Eunice, or even a greater number than in that genus, and often un- 
equal on the two sides, have but three tentacles, and cirrhi to perform the office of branchiae. 
Agla-Ura, Sav. — 
Hav6 likewise numerous jaws, of an unequal number, seven, nine, &c. ; but no tentacles, or which are 
entirely hidden ; and the gills are similarly reduced to cirrhi. 
Under this name I unite the Aglaura and CEnone of Savigny, and even certain species without tentacles, which 
MM. Audouin and Edwards leave in Lycidice, as Ag.fulgida and (E. lucida. 
The Nereids, properly so called (Nereis, Cuv. ; Lycoris, Sav.). 
Tentacles of an even number, attached to the sides of the base of the head, two other biarticulated 
ones a little more forward, and between these two simple ones ; only one pair of jaws within the 
trunk ; the gills formed of little laminas, traversed by a network of vessels ; and at each of their feet 
two tubercles, two bundles of bristles, and a cirrhus above and below. 
A great number of species inhabit our coasts. 
[The species here figured, N. prolifera (Mul- 
ler, Zool. Dan.), exhibits a singular peculiarity 
in its mode of propagation, merely by sponta- 
neous division, the hind part of the body being 
gradually transformed into an additional animal, 
the head and tentacular cirrhi being already de- 
veloped. Muller describes one mother, to which 
three foetuses, of different ages, appeared in one 
length. The mother had thirty segments, the 
young one nearest to it had eleven, and the two 
hinder, or older ones, seventeen segments each.]

After these should rank various genera, equally distinguished by a slender body, and gills reduced to 
simple laminae, or even to simple filaments or tubercles. Several, however, have no jaws nor tentacles. 
Phyllodoce, Sav. (Nereiphylla, Blainv.), — > 
In common with the Nereids proper, have tentacles of even number at the sides of the head, and four 
or five small ones anteriorly. They have distinct eyes ; their large trunk is furnished with a circlet 
of very short fleshy tubercles, does not contain jaws, and, what particularly distinguishes them, their
