T(/pe. — Museum d'Hi.stoire Naturellc, Paris; a portion of the type 

 in the United States National Museum. 



Remarl's. — The three particularly noteworth}^ characters of this 

 species are, {a) the imperfectly developed, but elevated wall ridge; ih) 

 the open, shallow valleys; (/) the sudden elevation of the septal margins 

 along the colline summits. The last-mentioned character separates 

 it from any of the previousl}^ described species.

One specimen was submitted to me, and on it the following descrip- 

 tion is based: 



Corallum of irregular shape, growth-form massive, attached by a 

 portion of the lower surface; calices confined to tlie upper surfaces 

 and the edges. There is no epitheca on the base, but outside the outer 

 corallites there is considerable vesicular exotheca. The outer surface 

 of this exotheca presents a minutely blistered and granulated appear- 

 ance, with longitudinal costal striations that become more prominent 

 on the periphery. Length, 152 nun.: width, 94 mm.; height, 86 mm.; 

 thickness of living portion, 42 mm
