THE SCARLET AND GOLD STAR-CORAL. 347 
the corallum wholly clothed with the scarlet integument, 
even down to the base. The covering was exceedingly 
thin, for with a needle-point I could feel the stony corallum 
without any sensible indentation of the surface, and the 
points at the margin were projecting. 
I have no information about the reproduction of the 
species, except such as may be gathered from the following 
observation. In the month of September, in a vase in 
which several specimens were kept, and which contained 
nothing else to which I could reasonably attribute the 
phenomenon, I found several clusters of ova. Each cluster 
consisted of about a dozen, loosely aggregated, and all con- 
nected by a kind of twisted cord, which formed a footstalk 
for each. The eggs were perfectly globular, ^\th of an 
inch in diameter, of a pellucid orange-yellow hue. One of 
them under the microscope showed the contents granular, 
and receding from the chorion, with a definite outline. 
None of them developed the embryo to my knowledge. 
The genus was established by i\Ir. Wood in 1844, to 
receive a fossil species from the Red Crag of Sutton. It 
now contains eleven species, most of them fossil, but one 
exists in the Italian seas, and two others elsewhere. There 
is none with which D. regia can be confounded. The 
generic name is derived from ^d\avo<;, an acorn or nut, 
and (f>vWov, a leaf, and the specific alludes to the royal 
colours in which the animal is arrayed.
