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

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

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

 more narrow. 



Height, 40 nHllim. ; longer axis of the calicle, 26 ; smaller axis, 

 19; the primary septa project 5. — (Edw. and Haime).

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

 tion given by Edwards and Haime. 



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

 the Panamian 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 varioixs 

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

 rudimentary or wanting. Coralla generally bi'oad and low, in com- 

 p und species usually foliaceous or encrusting, the growth chiefly 

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

 Walls imperfectly developed, often rudimentary or wanting, when 

 present usually forming the basal or attached portion. Intersei>tal 

 chambers generally open from top to bottom, though mostly partially 

 interrupted by transverse bars or trabiculie, which imite adjacent 

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

 Pavonia and Sklerastrma.

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
