not incrustiiig. The under surface with delicate concentric 

 epitlieca, not spinous. 



.Macclestield Bank, 40 fatli. 



MoiitijMra porosdj sp. n. 



Corallum funnini^ a tliiii spreading frond from 1 to 2 

 millim. in thickness ; surface uneven ; over tlie greater part 

 of the frond calices are developed on both sides, but occa- 

 sional patches of a concentrically-wrinkled non-spinou3 

 epitheca are present ; calices i'ew, irregularly scattered, not 

 prominent, about 5 millim. wide; sejita only rej)resented by 

 twelve subocpKil, nearly horizontal s{)inc3 round the margin; 

 ccenenchyma minutely eehiiiulate. 



A single Sj)ecimen taken alive. 



Macclestield Bank, 35 fath. 



Montipora^ sp. 



Corallum incrusting, thin ; upper surface uneven, with 

 occasional rounded papillai or tubercles. Calices about '75 

 millim. wide, with six septa and sometimes smaller inter- 

 mediate septa. Ccenenchyma finely echinulate. 



Macclestield Bank, depth 44 fath. 



Genus TURBINARIA, Oken. 



Turhinaria stellulata, Blainv., sp, 

 1834. Astraopora stelhdata, Blainv., var. 



A massive convex specimen ; surface reddish brown. 

 Calices irregularly arranged, 1 to 2 millim. apart; margins 

 slightly elevated, circular, nearly 2 millim. in width, very 

 deep ; twenty-four subequal vertical septa ; well developed 

 trabecular columella filling the base of calices. 



This form agrees fairly well with the descriptions of this 

 species, but the calices are closer arranged. 



Tizard Bank, 5 to 10 fathoms. 



Genus Madeepora, Linn. 



In the collection are no less than thirty-two species of this 

 genus, five of which were obtained in depths over 20 fath. 

 and are all, I believe, new. Four of them were from the 

 Macclesfield Bank, one from the Tizard Bank, and one was 

 common to both ; all these deep-water species were fragile, 

 and one was particularly beautiful {\f.fragiUs),
