tioned. Mr J. E. Gray, a high authority in matters of this kind, 
says, “ the Cymodocese appear to be only Sertulariae which have lost 
their cells,” (Synop. of Brit. Mus. p. 75) ; and Blainville makes the 
same assertion in reference to the above species.* Dr Fleming is of 
opinion that C. simplex has been established from an individual of 
Campanularia dichotoma in a depauperated state ; (Brit. Anim. 548,) 
while again Mr Hogg informs me that he is almost satisfied that this 
Cymodocea is Plumularia pinnata with its pinnse rubbed off by the 
waves or tide on the beach ; and the specimens he has sent me in 
confirmation of this supposition are certainly very exact to Lamou- 
roux’s figure, nat. size , — for it must be observed that his magnified fi- 
gure represents the polypidom as unjointed or continuous, whereas it 
is regularly jointed both in the Campanularia and Plumularia. But 
I make this remark not to invalidate the opinions either of Dr Flem- 
ing or Mr Hogg, for that of the latter I am disposed to adopt ; but it 
gives me an opportunity of warning the student against an implicit 
reliance on the figures of Lamouroux, which we are assured by Blain- 
ville, who has compared them with the specimens from which they 
were made, are in many instances very erroneous. 
* Milne-Edwards also adopts this view. Lam. Anim. s. Vert. 2de edit. ii.

“ All the works of the Lord are exceeding good : and none may say, What is 
this ? Wherefore is that ? for at time convenient they shall all be sought out 
All the works of the Lord are good : So that a man cannot say, This is worse 
than that ; for in time they shall all be well approved.” — Ecclesiasticus.
