Branching, also in irregularly lobate ma-sses. Corallites 

 sub])olygonal, varying considerably in size, the smaller, 2 to 

 3 niillim. in width, intermingled with the larger, which range 

 from 4 to 5 millim. and occasionally to 6 millira. 



Macclesfield Bank, 35 fath. 



Alveopora TizarcU, 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 calicc ; 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.
