before the septa of the first and second cycles. The columella is 

 fasciculate, not large, with a papillary upper termination. The 

 calicular fossa shallow. 



The dimensions of the type specimen are : diameter of the 

 calice, 3.5 mm. ; height of corallum, 4 mm. ; diameter of the area 

 of attachment i mm. (Adapted from Vaughan.)

Description. Corallum short cornute, rapidly increasing in 

 diameter, curved in the plane of the shorter transverse axis of 

 the calice, cross-section elliptical. The wall of the corallum is 

 solid and is apparantly covered by a thin, firm, pellicular epitheca, 

 that seems to be applied to the wall in the same way as is the 

 epitheca of Flabellum, although this can not be certainly deter- 

 mined because of the condition of preservation of the specimens. 

 The outer surface of the corallum wall usually shows several 

 longitudinal undulations, these being more numerous on the 

 concave than upon the convex side, and also low, rounded costse. 

 When perfectly preserved, fine, longitudinal, raised striae or longi- 

 tudinal rows of small low granules may be detected upon the 

 outer surface of the corallum. Septa about 64, the cycles 

 and systems not very distinct; the first and second cycles and 

 some members of the third reach the columellar space ; the mem- 

 bers of the third cycle usually fuse by their inner margins to the 

 sides of those of the second, thus inclosing the members of the 

 fourth cycle ; when members of the fifth cycle are present, those
