Description. The zoarium is an Eschara with claviform fronds; the two 

 lamellae are inseparable. The zooecia are distinct, elongated, elliptical; the frontal 

 is smooth, quite convex. The peristomice is orbicular; the peristonie is thin, sharp, 

 and bears laterally a very large triangular avicularium with pivot. The ovicell 

 is large, salient, imbedded in the distal zooecium, and opens into the peristomie. 

 On the frontal there is a large semicircular ascopore surmounted by two small 

 pores.
