 Cylindececium, Hincks. 



Cylindroecium giganteum^ Busk. 



In the specimens which I refer to this species, the cell is 

 of more slender habit than in British examples and the ecto- 

 cyst less opaque ; but these differences are of slight moment, 

 and I have little doubt that the Pacific form is specifically 

 identical with our own.

APPENDIX. 



Family Cellulariidje. 



Menipea ternata^ Ellis & Solander. 



The form occurs in which the two lower cells in the triplet are 

 much elongated and attenuated, and the habit in consequence 

 is much more slender and graceful than in the normal condi- 

 tion. Smitt has recorded this variety from the north.
