CATENICELLA COENUTA (Busk). 



Description. — Cells elongated, papillose in front. Vittse lateral, extending 

 the whole length of the cell. One or both lateral processes long, pointed and 

 recurved, frequently with a small aperture at the base. Ovicell galeate, surmounting 

 one of the cells of a geminate pair, terminal, with a sharp spine on the summit.

 pi. 10, f. 1, 2, 3. 



Queenscliff. 



Forms small greyish tufts, 1 to 2 inches high. The only- 

 species with which it is likely to be confounded is C. perforata, 

 from which it may be distinguished by the retrocedent, spinous, 

 lateral processes, and by the spine on the summit of the ovicell. 

 The long spine is frequently absent on one or both sides, and in its 

 place is a lateral process with a wide, gaping hollow, in which is 

 lodged an avicularium.
