 CELLEPORA BENEMUNITA (McG.). 



Description. — Zoarium small, encrusting'. Zooecia small, confused, heaped; 

 primary mouth with a sub-oral sinus ; several short, thick processes developed in 

 the neighbourhood of the mouth, surmounted by small avicularia with spatulate or 

 linguate mandibles. Numerous vicarious avicularia, with broadly spatulate man- 

 dibles. Ooecia small, sub-globular. 



Port Phillip Heads, Mr. J. Bracebridge Wilson. 



The only specimen I have seen is very small. It is readily 

 distinguished by the numerous short, glassy processes (many 

 surmounted by avicularia) in the neighbourhood of the mouth, 

 the numerous vicarious avicularia, and the smooth ooecia.
