366 APPENDIX. 



Fam. 1. SALICOHNARIAD^. Cells disposed around 



an ideal axis. 



9. Salicornaria, Cuvier. 



a. Surface di\dded into more or less regular hexagonal 

 spaces by elcA^ated ridges. 



1. S. punctata, n. sp. 



Cellaria salicornioides ? Audouin. Savigny, Egypt. 



PL 6. fig. 7. 



Hexagonal areas with an acute angle above and below ; 

 bottom of area pjTiform^ surface covered with minute 

 transparent granulations. Mouth of cell in the upper 

 thirds with a minute tooth on each side. 



Hab. — Bass Strait^ 45 fathoms. Off Cimiberland 

 Islands^ 27 fathoms^ fine grey mud. 



Parasitic upon Sertularians and Polyzoa ; branches strag- 

 gling of irregular lengths. 



2. S. bicornis. n. sp. 



Areas with an obtuse angle above and below, sometimes 

 rounded above ; a minute projection on each side near the 

 top. Bottom of area long-oval, smooth, sometimes with 

 a perforation above the mouth. Mouth mth a minute 

 tooth on each side. 



Hab. — Bass Strait, 45 fathoms. 



Parasitic. Branches shorter and thicker than in the pre- 

 ceding species. In the shape of the area they are very 

 much alike, but in S, bicornis, in some cells, and occa- 

 sionally throughout the greater part of the internode, the 

 area differs widely from the more usual form. It is much 

 expanded, and presents a wide arch above. In this case 

 there is usually a considerable-sized perforation above the 

 mouth of the cell, as occurs not unfrequently also in S .
