THE SCABLET 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, j^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 Mr. 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 Itahan seas, and two others elsewhere. There 

 is none with which B. regia can be confounded. The 

 generic name is derived from /3a\avo9, an acorn or nut, 

 and <f)v\\ov, a leaf, and the specific alludes to the royal 

 colours in which the animal is arrayed.
