I have occasionally met with it. I have not seen the original figure, 
but the copy of it given by Blainville, Man. d’Actinol. pi. 88, B, 
fig. 7, does not diminish the strength of my suspicion, which, how- 
ever, some may deem a very vague guess, when they observe that 
it has been referred even to a different genus, and forms the Anthelia 
rubra of the author just mentioned, Actinolog. p. 524 ; and the Sym- 
podium rubrum of Ehrenberg. Lam. Anim. s. Vert. 2de edit. ii. 625.

“ Base of adhesion narrow, body massive, surface irregular ; the 
skin consists of animal matter cementing innumerable round siliceous 
grains ; the cells leading from the stellate pores are indistinct ; the 
spicula, which converge towards the centre, are fusiform, grouped in 
small bundles, and many of them at the skin are tricuspidate. In a 
dried specimen from Zetland, which I have had an opportunity of ex- 
amining through the kindness of Professor Jameson, the surface is 
slightly villous, owing probably to the contraction of the skin, leav- 
ing the extremities of the fibres free. With the exception of the 
stellate pores, it agrees with the Alcyonium primum Dioscoridis of 
Donati ( Adriat. 56. t. ix. f. 1.) in the villous skin and the simple and 
tricuspidate spicula.” — Fleming. 
In the 2d edit, of Lamarck’s Anim. s. Vert. ii. 632, 1 find it stated 
that Ehrenberg considers the Alcyonium cydonium of Muller as 
founded on a young individual of Alcyonium digitatum, of which, in- 
deed, it has much the appearance ; but the zoophyte which Dr Flem- 
ing has had in view, seems to be different. 
* Cydonium — a quince, in allusion to the figure of the Zoophyte.
