CLASS ANNELIDA. 
Savigny, which nevertheless would appear to have gills al- 
together different. 
After these genera with complicated gills, we may place 
those in which they are reduced to simple laminae, or even 
to slight tubercles, or, in fine, in which the cirrhi alone 
supply their place. 
There are some which still are related to Eunice by the 
strong armature of their proboscis, and by their antennae being 
of odd numbers. 
Such are, 
Lysidice, Sav ., which with jaws similar to those of 
Eunice, or even more numerous, and often of odd numbers, 
have but three tentacula, and some cirrhi for gills, Lysidice 
Valentina , Sav. ; L. Olympia , id. ; L . galatina, id., Eg. 
Annel. p. 53. 
Ag LAURA, Sav., have also numerous jaws, and of odd 
numbers, as seven, nine, &c. ; but they want tentacula, or 
have them altogether concealed. Their gills are also reduced 
to the cirrhi. 
I unite the AGLAURiE and the ®nona: of Savigny ; and 
even certain species without tentacula, which MM. Audouin 
and Milne Edwards leave in the Lysidicae, Ag. fulgida, Eg. 
Annel. v. 2 ; (Enone hicida, ib. f. 3. 
Nereis, (proper) Cuv. 9 Lycoris, Sav., have tentacula of 
even numbers, attached to the sides of the base of the head, 
and a little further forwards, two others, biarticulate, between 
which are two simple ones. They have but one pair of jaws 
in their proboscis ; their gills only form small laminae, over 
which is spread a net-work of vessels. There are, besides, 
to each foot two tubercles, two bundles of bristles, a cirrhus 
above, and another below. 
We have a tolerable number of them on our coasts. Nereis
