 CATENICELLA BUSKII (Wtv. Thomson). 



Description. — Cells very much elongated, narrow. Vittse very narrow and 

 extending' the whole length of the cells. Ovicell galeate, superior, projecting on 

 the surface of the cell above, with which it is incorporated, with a beaded border. 



Reference. — Wyville Thomson, Dublin Natural History Review, April 1858. 



A small species growing on other polyzoa ; rare. Readily dis- 

 tiuguislied from the other small species by the long, entirely lateral 

 vittse, and the aduate beaded ovicell.

 CATENICELLA HANNAFORDI (P. MacGil.). 



Description. — Cells wide, ovoid or subglobular. Lateral processes large, 

 gaping, directed forwards, usually equal on both sides. VittiE narrow, entirely 

 lateral, extending the whole length of the cell. Anterior surface smooth, or very

Lady Bay, Portland, adhering to algas ; Mr. Hannaford. 



This species may be distinguished by the large gaping avicu- 

 larian processes, directed a good deal forwards, and almost sur- 

 rounding the mouth and the narrow entirely lateral vittse. 



Its closest ally is C. ritigens, which I have not seen.
