 BEANIA INTERMEDIA (Hincks, sp.). 



[Genus BEANIA (.Johnston). (Sub-kingdom MoUusca. Class Polyzoa. Order Infun-r 

 dibulata. Sub-order Cheilostomata. Taiuily Bicetlariida;.) 



Gen. Char. — Zoarium creeping or loosely adnate. Zooecia disjunct, connected by (usually) 

 corneous tubes, erect or decumbent, ovate or boat-shaped, entirely open in front and filled in by a 

 thin membrane. Usually a capitate, pedunculate avicularium, perfect, aborted, or altered in 

 form, on one or both sides towards the upper extremity, in some species absent.] 



Description. — Zooecia much elongated, narrow, sub-erect, anterior extremity 

 rounded, posterior narrow, two short spines or denticles above, and one longer on 

 each side; a capitate avicularium on each side above the lower spine. Each 

 zooeciiim connected with one in front bj- a considerable tube arising- from the back 

 and with one on each side by a tube near the posterior extremity. Posterior surface 

 smooth. 



Reference. — Diachoris intermedia, Hincks, Ann. and Mag. Nat. Hist., Aug., 



Port Phillip Heads, Mr. J. Bracebridge Wilson. 



The ouly specimen I have examined is not in very good con- 

 dition, but there can be no doubt of its identity with Hincks' 

 species. The points of origin of the lateral connecting tubes seem 

 to vary. In my specimen they are mostly near the posterior 

 extremity, while Hincks describes them as being a little above the 

 middle ; in one of the figured zooecia it will be seen that they are 

 not opposite, one being much farther forward than the other.

 BEANIA CONFERTA (McG.). 



Description. — Zooecia large, each connected with six others by very short 

 tubes ; six large, articulated spines above, of which two from the summit project 

 nearly directly forward, a similar jiair (one on each side) originating a little farther 

 back point in the same direction, and the third pair, arising opposite the lower edge 

 of the mouth, project upwards and forwards and are curved inwards at their bases ; on 

 each side of the aperture a double row of long, stout spines, the outer directed forwards
