 coencnchyme has a finely granular appearance. The basal 

 stems have a slightly quadrangular appearance. Short branches, 

 which are often expanded at iheir tips, fairly frequently arise 

 from the internodcs above the basals. 



The anthocodias have the spicules, which are mainly 

 spindles arranged m eight longitudinal areas, and at the base 

 of these lies a circular hand of spindles (with almost entire

 in a vertical direction. The calyx is densely protected by 

 spicules, mainly spindles and clubs, which cross and overlie 

 one another in an intricate manner. The basal attachment is 

 large and reptant. it is 3 by 2 cm. in diameter. Three large 

 shoots originate from the base, one of which is g by 8 mm. in 

 diameter. The upper branches are very much curved, and are 

 sometimes 2 mm. in diameter, the polyps arc there closely adja-
