Family Liriozoid^e. 



Zoarium calcareous, formed by a creeping stolon givino- orii^iii to jointed branches, 

 each inti'i iiodo consisting of single modified tubular cells connected end to end by 

 corneous joints. Zocccia united laterally in clusters articulated to the sides of ilie 

 internodes, subtubular, thyrostomc oblique. 



Liriozoa, Lamarck.

J'limar}' y.oo'cinni comi)icssed laterally, produced inferiorly as a long calcareous 

 tube ; thyrostomc almost ti;rminal, elliptical vertically ; lateral zorocia attached by 

 their backs throughout their whole length to the primar}-, expanded above, thyros- 

 tomc terminal, ellii)tical, with a sinus below, directed upwards and slightly outwards
