ORDER TUBICOL/E.

Zool., Dan. xxvi., of which Bruguieres has made his Amphi- 
trite doree. 
The South Sea produces a larger species, Amphitrite auri - 
coma Capenns , Pall., Miscel. ix. 1, 2, whose tube, thin and 
polished, has the appearance of being transversely fibrous, 
and formed of some dried, soft and stringy substance. It is 
the same as Sabella chrysodon , Gin., Bergius Mem. de 
Stockh. 1765, ix. 1, 3. ; as Sabella capensis , Id. Stat , Mull., 
Nat, Syst. VI. xix. 67, which is only a copy of Bergius ; as 
Sabella Indica , Abildgaart., Berl., Sclir. IX. iv. See also 
Mart., Slabber., Mem. de Flessing. I. ii. 1 — 3. 
Other Amphitritae inhabit factitious tubes, fixed to submarine 
bodies. Their gilded bristles form on their heads many con- 
centric crowns, from which results an operculum, which closes 
their tube when they contract themselves in it, and the two 
parts of which may be separated. They have a cirrus to 
each foot. Their body is terminated behind by a tube bent 
towards the head, without doubt to emit the excrements. I 
have found a muscular gizzard in them. They are the 
Sabellarice of Lamarck, and the HermelUe of Savigny. 
Such is the species found along our coasts, Sabella alveo - 
lata , Gm., Tubipora arenosa , Linn. Ed. xii. Ellis. Corail, 
xxxvi., in which the tubes, united to each other in a com- 
pact mass, exhibit their orifices, pretty regularly arranged, 
somewhat like the cells of bees. 
N. B. It is here, perhaps, that the Amphitrite plumosa of 
Fab., Faun., Green, p. 288 ; and Mull., Zool., Dan. xc., ought 
to come. But the descriptions are so obscure, and agree so 
little together, that I dare not place it. M. de Blainville 
makes of it his genus Pherusa . 
Another, Amph . ostrearia , Cuv., establishes its tubes on 
the shells of oysters, and is said to injure their propagation 
very much. 
I suspect that it is to this order that we must refer, —
