The figure of Alcyonium Lobatwn of Lamonroux apparent 
belongs to this species ; but it is so faintly executed, that 
is uncertain whether it belongs to this or another; I belie 
it belongs to this, though not very characteristic ; a charac * 
which may be applied to many other of his figures. * j 1 
figure of the Cydonium Mnlleri in Jones’ “ Outlines of 1 ^ 
Animal Kingdom,” p. 27, fig. 5, also probably belong* 
this, though I quoted it in the paper in the Po!ytecb% 
Report as the true Cydonium. Johnston’s figure is g 0 ^- 
and characteristic of the expanded state. The tentacul* 
the polypes are liable to such a variety of appearances, d 
pending on their partial or complete expansion, that we oil? 
not to decide on specific differences hastily on such grouo ' 
The differences between the different polypes figured by 
are great, and they differ from those of Lamouroux 
correspond to the polypes of this species, and from Johns® 0 
which most closely resemble those that. I have observed 
ALCYONIUM SANGUINEUM. Encrusting, fleshy, ^ 
deeply lobulated ; lobules elongated cylindrical, and e , 
tending nearly as low as the base ; of a deep blood * ( 
colour. Polype-cells depressed, yellow, small, with C# 
rays, numerous. Skin coriaceous. PI. 13, fig. 2. , 
Of this species I have procured only a single specimen ■ 
that, not far from land ; in general appearance it rese® 0 
the last species the Alcyonium digitatum, but differs fr 01 ^^ 
in several important particulars. Its surface is rather ro u ' f , 
coriaceous, and occupied by numerous spieula. The s ' 
shaped depressions, which arc numerous, are slightly ^ 
pressed, yellow and marked with eight rays. The 
which are imbedded, are inversely conical and ter® ,D | j6 
interiorly in long canals, which pass irregularly through, 
fleshy polype-mass, and opening into each other in all d” e i 
tions give the substance the appearance of irregular 
work, the meshes of which are filled up with minute l' ! 9 , 
a gelatinous substance and spieula. Thus the internal 0 j 
tomy resembles that of the Al. digitatum, but is smaller j 
more delicate. The colour externally is of a deep b 
colour and internally is but slightly lighter.
