According to Gray's diagnosis the colony is branched and tree-like, with short, 

 divergent, approximately quadi-angular branches which sometimes anastomose. The 

 polyp calyces are short, and disposed in two or three irregular rows on each side of the 

 branches. The ccenenchyma is granular ; lateral grooves are distinct. Spicules like 

 those of Goryonella.

 Mus., 1870, p. 32. 



According to Gray's diagnosis the colony is tree-like, dichotomou.sly branched. 

 The twigs are upright and divergent. The lower twigs sometimes anastomose. The 

 ccenenchyma is hard and granular. The calyces project and are subcyUndrical in 

 form, short, rather curved. They occur in two, three, or four alternating rows on 

 the sides of the twigs, and irregularly on the branches. The axis is hard, calcareous
