CORALLIFERI, 437 



T. indivisa, Lam.; Ellis, Corall., XVI, c, is found on the 

 coast of France ; its tubes are simple and two or three inches 

 liigh, resembling pieces of straw *. 



TiBiANA, Lamour., 

 7Ag7:^g tubes presenting a small open branch at each angle f. 



CORNULARIA, Luvi., 



Where the tubes are conical, from each of which issues a Polypus 

 with eight dentated arms, like those of the Alcyoniee, Gorgonioe, 

 &c. : In 



Anguainria, Lam., 

 The tubes arc small, cylindrical, and adhere to a creeping stem, each 

 one opening laterally, and near the extremity, for the passage of a 

 Polypus §. In 



Campanularia, Lam., 

 The extremities of the branches through which the Polypi pass are 

 Avidened and bell-shaped. 



Lamouroux separates them into Clytia where the stems are san- 

 dent il : 



And Laomedea where they are not; the bells also are smaller and 

 the branches shorter \ 



Sertularia, Lin. 



The Sertulariae have a corneous stem, sometimes simple, sometimes 

 ramous, on the sides of which are cells, extremely various in form, 

 that are occupied by the Polypi, all connected with a gelatinous 

 stem that traverses the axis, like the medulla of a tree. They propa- 

 gate by ova or buds, which arc developed in cells larger than the rest, 

 and of a different form. 



The various directions of their cells have caused them to be sub 

 divided. 



Aglaophenia, Lamour. — Plumularia, Lam., 

 Where the little cells are arranged on one side only of the branches**.

f Tibianu fasciculata, Lamour., Polyp. Flex., pi. vii, f. 3, a. 



Here, Lamouroux places Liagores, Tklestio and Neomeris, subgenera which 

 perhaps would be as well arranged in the vicinity of the hollow Coralliupe. 



X Tubularia cornucopia. N. B. The pretended Tubularioe of Esper, pi. xi — 

 xxvi, merely represent the envelopes of ova of some Mollusca Gasteropoda, the 

 eighteenth excepted, which is a Galaxaura.

 this name to Aetea,
