the axes as 100 : 157. The septa are proportionally less projecting, 

 and one can distinguish on their sides lines of fine and very scattered 

 grains, parallel to the superior edge ; the fosette of the calicle is still 

 more narrow.

This species I have not seen, and therefore reproduce the descrip- 

 tion given hy Edwards and Haime. 



As it was collected by Mr. Hugh Cuming, it probably belongs to 

 the Paiiamian fauna.

Polyps short and broad, not exsert, either simple, or becoming com- 

 pound by marginal budd ng, rarely by fissiparity; in compound 

 species the in ividual polyps are usually not clearly separated by 

 definite walls, the septa of adjacent cells blending. Tentacles various 

 ill number and form, usually short and lobe-like, or bilobed, often 

 rudimentary or wanting, Coralla generally broad and low, in com- 

 pound species usually foliaceous or encrusting, the growth chiefly 

 centrifugal, the septal system composing the chief part of the coral. 

 Walls mperfectly developed, often rudimentaiy or wanting, when 

 present usually forming the basal or attached portion. Interseptal 

 chambers generally open from top to bottom, though mostly partially 

 interrupted by transverse bars or trabictihi?, which unite adjacent 

 septa ; but sometimes crossed by well formed dissepiments, as in 

 Puvonia and Siderastrma.

Coralla simple or compound, free or attached, low and broad, 

 the compound forms often foliaceous. Walls basal, little developed, 

 often strongly costate, perforated by irregu ar openings, destitute of
