CORALLIFERI. 395 
tinous body traverses the axis, like the medulla of a tree, and 
that are open, either on the summit or sides, to allow the pas- 
sage of the Polypi. 
Their more simple Polypi appear to be chiefly analogous 
to the Hydre and Cristatell(1). 
Tuprpora, Lin. 
Simple tubes of a stony substance, each containing a Polypus. 
These tubes are parallel, and united from space to space by trans- 
verse laminz, which has caused them to be compared to the pipes 
of an organ. The most common species. 
T. musica, L.; Seb., III, cx, 89, is of a beautiful red; its po- 
lypi are green, and formed like Hydre. Very abundant in the 
archipelago of India(2). 
It appears that we must approximate to the Tubipora certain 
fossil Coralliferi (Polypiers) also composed of simple tubes, such as 
the Carenrpora, Lam., where the tubes are deposited in lines that 
intercept vacant meshes(3); the Favosires, id.(4), composed of 
crowded hexagonal tubes, &c. 
Tusunaria, Linn. 
Simple or branched tubes of a horny substance, from the extremities 
of which issue the Polypi. 
priety of the attempts to establish the use of French terms in the Sciences, now 
being made, notwithstanding the inconvenience, confusion and error they are sure 
to produce. 
The term polypier, for which we have no adequate word, has lately been coined 
to express the common part of these compound animals, or the substance we usually 
denominate Coral,—Corallium—and as it is an excretion, I have ventured to ren- 
der Polypes 2 Polypiers by Polypi coralliferi, and the term polypiers by the word 
coral. Am. Ed.

(2) The other Tubipore of Gmelin do not belong to this genus; some of them, 
those of Fab., Groenl., in particular, are perhaps tubes of Annelides, but the sup- 
position that the above animal belongs to this last mentioned class is erroneous. It 
is atrue Polypus. See Quoy and Gaym., Zool., de Freycin., pl. 88.
