The individual calyces are min u te, almost entirely included even when the polyps are 

 partly expanded, and about 1 mm. in diameter. They are rendered conspicuous by their color 

 which is a brilliant crimson while the general ccenenchyma is a yellowish red or deep orange. 

 Their walls are filled with crimson spicules which look like small imbricating <lisks when in 

 situ. The polyps are quite heavily spiculated. There is a strong collaret often of crimson, some- 

 times of light yellow spicules, above which is a pair of spicules forming a point above 1 

 tentacle base l>y the approximation of their distal ends. These spicules are also often crimson 

 in color. Above these points other strong spindles He along the distal parts of th<- dorsal

The ccenenchyma of the branches appears to be filled with rounded or disk like imbri-
