18 CLASS AXNELIDA. , 



Arenicol. clavata. Ranzani. dec. i. p. 6. pi. i. f. 1. ; if indeed 

 it be a distinct species. 



Amphinome, Brug.y 



Have on each of the rings of the body a pair of gills, in the 

 form of a tuft or plume, more or less complicated, and to each 

 of their feet two packets of separate bristles, and two ciiThi. 

 Their proboscis has no jaws. 



This genus has been justly withdrawn by Bruguieres from 

 the ApJiroditcB of Pallas, and the Terebellce of Gm. With M. 

 de Savigny it is the type of a family, which he names, Amphi- 

 nome, also adopted by his successors. 



M. Savigny divides them into 



Chloeta, Sav., which have five tentacula to the head, 

 and the gills in the form of a tripinnate leaf. 



The Indian Ocean produces one of them, the Ainphinome cJie- 

 velue, Brug. ; Terehellajlava, Gm., Pall., Miscel.,viii. 7 — 11., 

 extremely remarkable for its long bundles of lemon-coloured 

 bristles, and the beautiful purple plumes of its gills. Its form 

 is broad and depressed ; it has a vertical crest on the snout. 



And into 



Pleione, Sav. Amphinome, Blainv., which, with the 

 same tentacula, have gills in the form of tufts. They are also 

 of the Indian seas, and there are some very large ; Terehella 

 carunculata, Gm. ; Aphr. car. Pall., Miscell. viii. 12, 13 ; Ter. 

 rostrata, ib. 14 — 18 ; Ter. complanata, ibid. 19 — 26; Pleione 

 alcyonia, Sav., Eg. Annel. ii. f. 3. 



He adds here, Euphrosyne, Sav., which have but a 

 single tentaculum in the head, and whose tree-like gills are 

 very much developed and complicated, Enplirosyne laureata, 

 Id., ibid. f. 1 ; jE. mirtosa, id. ib. 2. 



N.B. It is also near Amphinome that the genus Aris- 

 tenia should come, Sav-, Eg. Annel. pi. ii. f. 4 ; but it is 

 only established on a mutilated individual.
