NEMATOIDEA, 359 
In a sixth, 
CLAVELLA, Oken, 
We find none of these appendages, the animal merely fastening 
itself by the mouth(1). 
In these three last groups the hooks of the mouth are well marked; 
their strings are but slightly elongated, and sometimes the posterior 
portion of the body is provided with other appendages. 
In consequence of a recent examination, I place here the 
Cuonpracantuus, Laroch. 
Where the mouth is also furnished with hooks, and the sides of 
the body with appendages, so extremely various as to form and num- 
ber, that in process of time we shall have to subdivide them. 
Thus, in some, we observe on each side two sorts of arms more or 
less elongated(2). 
In others there are several pairs partly forked(3), or even more 
ramous(4). 
Some again have a slender neck, and a wide body slashed on the 
edges(5). 
Act. Suec., 1751, and Encyc. Méthod., Vers, pl. LXX VIII, f. 13, 18;—Z. Pernet- 
tiana, Blainy.; Pernetti, Voy. aux Malouines, I, pl. i, f. 5, 6—two badly figured 
species. The ZL. huchonis, Schrank., Tray. in Bay. pl. I, f. A, D, is still worse. 
There are several others. 
I think that this and the preceding group will re-enter the Dita eo 
_ Blainy., which in that case must be differently defined. 
(1) teens uncinata, Miill., Zool. Dan., 1, xxxiii, 2;—JZ. clavata, Id., Ib., i. 
These Cravertm of Oken form the Barwa proper of M. de Blainyille. 
(2) Lernza radiata, Miill., Zool. Dan., XXXII, 4;—L. gobina, Id., Ib., 3. The 
first is the type of the genus Anonzs, Oken. 
(3) Lernzxa cornuta, Id., Ib., 6, and several new species. 
(4) Chondracanthus zei, Laroche, Bullet. des Sc., May 1811, pl. 2, f. 2. 
(5) Lerneza trigle, Blainy., Dict. des Sc. Nat., xxvi, p. 325; Cuv. Régn. Anim., 
pl. xv. 
N.L. M. de Blainville arranges my Chondracanthi in his genera LERNEENTOME, 
LErnacantue and LeErNANTHROPE. 
'N.B. The Lernza pectoralis, Miill., Zool. Dan., XX XIII, f. 1, is a Calygus, and 
the Z. asellina, It. West. Goth., II, 4, also seems to be one of the same, but dis- 
figured,
