Zoarium consisting of extremely thin foliaceous expansions 

 incrusting other objects ; all the specimens are incrusting cyatho- 

 phylloid corals ; greatest thickness observed, .20 mm. Cells some- 

 times polygonal, but usually circular or oval, walls thick ; diameter 

 .33 mm., either irregularly disposed, or forming intersecting rows. 

 Interstitial cellules minute, ra:yely a cell is entirely surrounded by 

 them ; sometimes there are only one or two for each cell, and at 

 other times for a considerable space the cells are in contact, with- 

 out intermediate cellules. Surface marked by maculae or very 

 slightly elevated monticules, the centers of which are distant 

 about 3.50 mm. ; a space 1.50 mm. in diameter being occupied by 

 cells larger than the others, and having a diameter of about .50 mm. 



This species may be distinguished from others of this formation 

 by, the more nearly circular or oval cells, and their crowded or 

 confused appearance.
