Corallites low, height up to 6 mm, cylindrical to trochoid, connected 

 at their bases, sometimes with extrathecal deposit between corallites, 

 commensal worm tube in base; some corallites with a slight epitheca; 

 calices subcircular, largest 4.5 by 5 mm; septa 38-42 in largest speci- 

 mens, as few as 20 in smaller specimens, septa arranged in a Pourtales 

 plan, somewhat obscured by a large columella and numerous paliform 

 teeth; septal interspaces 1-2 times as wide as thickness of primary septa; 

 paliform teeth prominent, irregularly projecting, present on all except 

 last cycle of septa; first and second cycles with 2-3 teeth, third cycle 

 usually with 2 paliform teeth; septal margins above paliform teeth 

 dentate; first cycle septa very exsert, later cycles slightly less exsert, 

 with fourth cycle septa adjacent to first cycle taller than second cycle; 

 septa rather narrow at top, sharply rounded from costal edge, descending 

 obliquely into a moderately deep calice ; inner edges of septa with occa- 

 sional perforations; septal faces with fairly large, uniform, pointed or 

 slightly blunt granules; costae subequal, low, broad, with moderately 

 heavy granules, continuous to corallum base, interspaces one-fourth to 

 one-third as wide as septa, columella not projecting above bottom of 

 calice, composed of 12-14 interlacing paliform teeth.
