456 ANNELIDES. 



Eunice, Cuv.(l) 



The branchiae are also plumose, but the proboscis is well armed 

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

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

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

 find two small eyes. 



Eu7i. gigantea, 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^, 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. Dan., I, xviii, 1 5, inhabits a horny tube(4). 



After these genera with complex branchisEj we may place 

 those where they are reduced to simple laminae 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 antennae. Such 

 is the 



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 Apollodorus. M. Savigny makes it the 

 name of a family, and calls the genus Leodice. M. de Blainville has changed these 

 names, first to Branchionereis, and then to Nereidon. 



(2) Nereis norvegica, Gm., Mull., Zool. Dan., 1, xxix, 1; N. pinnata, lb., 2; 

 N. cuprea, Bosc, Ver., I, v, 1; Leodice gallica, and L. hispanica, Sa.v\g. Add 

 Leod. antcnnata, Sav., Annel., V, 1; Eunice hellii, Aud., and Edvv., Litt., de la 

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



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



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

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

 Eteone, Sav., although the branchiae of the latter are very different.
