Family Bicellariid^}. 



Zoarium phytoid, erect and continuous, or adnate. Zooecia continuous, loosely 

 united or disjunct and connected by corneous tubes, obconic or boat-shaped, wholly

Zoarium creeping or loosely actuate. Zocecia disjunct, connected by (usually) 

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

 both sides towards the upper extremity. 



1. JB. spinigera, McGK 



Diachoris spinigera, McG., P.Z.V., 36. 



I have a single specimen of a Diachoris from Schnapper Point, in a broken 

 calcareous nodule, showing only the posterior surface. It is impossible to say to 

 which species it belongs, but it seems to be B. spinigera. 



Family Cellariid^e. 



Zoarium erect, branched and cylindrical, or quadrate, with the Zooecia arranged 

 around an imaginary axis, or expanded lobed and bilaminate. Zooecia separated by 

 raised margins, with depressed entirely calcareous surface. Ocecia internal and 

 opening by a special pore. 



Cellaria, Lamouroux.
