456 ANNELIDES. 



Eunice, Cuv.(l) 



The branchias are also plumose, but the proboscis it. ucll armed 

 with three pair ot" differently formed horny jaws; each foot is fur- 

 nished with two cirri and a bundle of setae, there are five tentacula 

 above the mouth and two on the nape. In some species only do we 

 find two small eyes. 



Eun. gigantca, Cuv. The largest of the known Annelides, 

 being upwards of four feet in length. From the sea of the An- 

 tilles'. 

 •Several smaller species are found on the coast'of France(2). 

 By the name of Marphis^e, M. Savigny distinguishes those spe- 

 cies, otherwise very similar, in which the two tentacula on the nape 

 are wanting; their upper cirrus is very short(3). 



A species at least closely allied to them, — N. tubicola, Mull., 

 Zool. Dun., I, xviii, 1 — 5, inhabits a horny tube(4). 



After these genera with complex branchiae, we may place 

 those where they are reduced to simple laminse* or slight 

 tubercles, or in which they are even replaced by cirri. 



Some of them are still allied to the Eunices, by the strong 

 armature of their proboscis, and their azygous antennee. Such 

 is tlie 



Lysidice, Sav. 

 Where, with jaws similar to those of the Eunices, and even more 

 numerous and frequently azygous, the only branchiae consist of three 

 tentacula and the cirri(5). 



Aglaura, Sav. 

 The jaws of the Aglaurae are also numerous and azygous, con- 



(1) Eunice, the name of a Nereis in ApoUodorus. M. Savigny makes it the 

 name of a family, and calls the genns Leodice. M. de Blainvillc has changed these 

 names, first to Brancldoncreis, and then to Nereidon. 



(2) Nereis norvegica, Wtn., Mull., Zool. Dan., I, xxix, \;^N. pinnuta, lb., 2; — 

 N. cuprea, liosc, 'Ver., I, v, 1; — Leodice gallicu, ixnd L. Jiispanic<i, Savig. — Add 

 Leod. antainata, Sav., Annel., V, 1; — Eunice htllii, Aud., and Edw., Litt., de la 

 Fr. , Annel., pi. iii, f. 1 — 4; — Eun. harassii, lb., f. v, 11. 



(3) Nereis sanguinea, Montag., Lin. Trans., XI, pi. 3. 



(4) After the Eunices probably should come the Nereis cmssa, Mull., Ver., pi. 

 xii, which, without having seen it, M. de Blalnville proposes to refer to the genus 

 Eteose, Sav., although the branchize of the latter are very different.
