Genus CELLEPORA Linnaeus, 1767 



CELLEPORA SINENSIS, new species 



Plate 63, fig. 5 



Description. — The zoarium is free, cylindrical, bifurcated. The 

 zooecia are indistinct, irregularly erect; the frontal is covered b} r 

 raised perforated protuberances which are avicularian chambers; 

 their orifice is poriform or elliptical and with pivot. The aperture 

 is little visible and buried at the bottom of a long peristomie; the 

 peristomice is very irregular, suborbicular or transverse. The 

 zoarial avicularia are rare, triangular, pointed; their pivot bears 

 a median hook. 



Affinities. — In its zoarium this species resembles very much Costazia 

 yarraensis, but its structure is entirely different; the numerous small 

 intcrzooecial avicularia arranged on the frontal are very characteristic. 



Our specimens were dead and nonovicelled. We have not then 

 been able to class this species generically and we place it in the old 

 group Cettepora which is now rejected as a valid genus.

Family LIRIOZOIDAE Levinsen, 1909 



"The slender, elongated zooecia, which may have a single spine 

 at the distal end, are provided as a rule with scattered pores and the 

 lateral walls with one or several uniporous Beptulae. The aperture 

 has a broad and low sinus and a weakly chitinized operculum. Avic- 

 ularia and ovicells are wanting. Free, jointed colonies with the 

 zooecia arranged in pairs or in triads; in the latter case they arise from 

 an axis consisting of kenozooecia." (Levinsen 1909.)
