Corals mostly branched, often encrusting when young ; sometimes 

 lobulate or massive, increasing by budding. Calicles small, stellate, 

 inmersed, usually separated by rather abundant exothecal coenen- 

 chyma, not entirely solid, and often granulated or striated on the 

 surface. Septa generally either 10 or 12. Loculi between the septa 

 not filled up below by stereoplasm. Columella various. Polyps 

 exserl in expansion, usually with 12, 20, or 24 tentacles. 



This family is chiefly Indo-Pacific, where it is represented by 

 numerous species of Stylophora.
