FAMILY I. 



TUBULARII. 



Those of the first inhabit tubes of which the common gelatinous 

 body traverses the axis, like the medulla of a tree, and that are open, 

 cither on the summit or sides, to allow the passage of the Polypi. 



Their more simple Polypi appear to be chiefly analogous to the Hy- 

 drae and Cristatellee (a). 



TuBiPORA, Lin. 



Simple tubes of a stony substance, each containing a Polypus. 

 These tubes are parallel, and united from space to space by trans- 

 verse lamina^, which has caused them to be compared to the pipes of 

 an organ. The most common species, 



T. musica, L. ; Seb., Ill, ex, 89, is of a beautiful red ; its po- 

 lypi are green, and formed like Hydrse. Very abundant in the 

 archipelago of India *. 

 It appears that we must approximate to the Tubipora certain 

 fossil Coraliiferi (^Polypiers) also composed of simple tubes, such as 

 the Catenipora, Lam., where the tubes are deposited in lines that 

 intercept vacant meshes t; the Favosites, id. J, composed of 

 crowded hexagonal tubes, &c. 



TUBULARIA, Lin. 



Simple or branched tubes of a horny substance, from the extremi- 

 ties of which issue the PolyiJi. 



The Polypi of the fresh water Tubularipe— Plumatella, Bosc. § — 

 seem to be closely approximated to the Cristatellse by the disposition 

 of their Tentacula. 



Certain species are found in France, that creep over the plants 

 of stagnant waters ||. 



Tubularia Marina, 

 The Polypi of those that inhabit salt water have two ranges of 

 tentacula, the outer one forming radii, and the inner turning up into 

 a tuft. One Species, 



* The other Tubiporse of Gmelin do not belong to this genus ; some of them, 

 those of Fab., Groeul., in particular, are perhaps tubes of Annclides, but the suppo- 

 sition that the above animal belongs to this last-mentioned class is erroneous. It 

 is a true Polypus. See Quoy and Gaym., Zoo!., de Freycin., pi. SS.
