Branching, also in irregularlj lobate masses. Corallites 

 subpolygonal, varying considerably in size, the smaller, 2 to

Alveopora Tizardi, sp. n, 



Corallum growing in flattened irregularly lobate expansions j 

 under surface uneven and covered by delicate wrinkled epi- 

 theca, Calices polygonal, from 1 to 1'3 millim. in diameter ; 

 twelve septa, of the usual spinous character, alternate longer 

 and shorter, but none reach the centre of the calice ; calice 

 shallow, the space occupied by the septal spines ; walls very 

 cribrate, so that the corallum is light and spongy in character. 



This species is mainly characterized by the small size of 

 the corallites. Only a single specimen obtained.
