CLASS ANNELIDA. 
Arenicol. clavata. Ranzani. dec. i. p. 6. pi. i. f. 1. ; if indeed 
it be a distinct species. 
Amphinome, Brag ., 
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 cirrhi. 
Their proboscis has no jaws. 
This genus has been justly withdrawn by Bruguieres from 
the Aphrodite of Pallas, and the Terebella of Gm. With M. 
de Savigny it is the type of a family, which he names Amplii- 
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 Amphinome che- 
velue , Brag. ; Terebella flam. , 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 ; Terebella 
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, Eupiirosyne, Sav., which have but a 
single tentaculum in the head, and whose tree-like gills are 
very much developed and complicated, Eupiirosyne laureata , 
Id., ibid. f. 1 ; E . 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.
