N. B. The Nereis verrucosa , Mull., vers. pi. vii. and incisa , 
Ott., Fabr. Soc. dTIist Nat. de Copenh. v. 1st part, pi. iv. 
f. 1 — 3, appear to have the head of lycoris, but with long- 
filaments in place of gills. They require a fresh exami- 
nation. 
Near these Nereides are grouped many genera, likewise 
with slender body, and gills reduced to simple laminae, or 
even to simple threads or tubercles. Many are destitute of 
jaws or of tentacula. 
Phyllodoce, Sav ., Nereiphylla, Blainv ., have, like 
the true nereides, an even number of tentacula, at the sides 
of the head, and four or five small ones besides, in front. 
They have eyes ; their large proboscis, furnished with a circle 
of very short fleshy tubercles, shows no jaws, and they are 
especially distinguished by having gills in the form of rather 
broad leaves over-lapping each other in a single row on each 
side of the body, and over them are spread some vessels ex- 
tremely ramified. 
Nereis lamellifera Atlantica , Pall., Nov. act. Petrop. ii. 
pi. v. fig. 11 — 18; perhaps the same as the Nereiphylle de 
Pareto , Blainv., Diet, des Sc. Nat.; N. flam, Ott., Fab., 
Soc. d’Hist,. Nat. de Copenh. v. part i. pi. iv. f. 8 — 10. 
N. B. N. viridis, Mull., vers. pi. xl. of which M. Savigny, 
without having seen it, proposes to form the genus Eulalia 
and the two Eunomia, Risso, Europ. Merid. iv. p. 420., 
appear to me to be also phyllodocce ; perhaps we should even 
refer to them the Nereis pinnigera , Mon tag., Linn. Trans. 
IX. vi. 3 ; and the Ne?$is stellifera . Mull., Zool. Dan. pi. lxii. 
f. 1., of which M. Savigny, without having seen it, proposes 
to make a genus, under the name of Lepidia ; and the
