Corals from the China Sea . 451 
not incrusting. The under surface with delicate concentric 
epitheca, not spinous. 
Macclesfield Bank, 40 fath. 
Montipora porosa , sp. n. 
Corallum forming a tiiin spreading frond from 1 to 2 
Tnillim. in thickness ; surface uneven ; over the greater part 
of the frond ealices are developed on both sides, but occa- 
sional patches of a concentrically-wrinkled non-spinous 
epitheca are present ; calices few, irregularly scattered, not 
prominent, about 5 millim. wide ; septa only represented by 
twelve subequal, nearly horizontal spines round the margin ; 
coenenchyma minutely echinulate. 
A single specimen taken alive. 
Macclesfield Bank, 35 fath. 
Montipora , sp. 
Corallum incrusting, thin ; upper surface uneven, with 
occasional rounded papillae or tubercles. Calices about *75 
millim. wide, with six septa and sometimes smaller inter- 
mediate septa. Coenenchyma finely echinulate. 
Macclesfield Bank, depth 44 fath. 
Genus Tukbinaria, Oken. 
Turbinaria stellulata , Blainv., sp. 
1834. Astrceopora stellulata , 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 Madrepora, 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 (M. frag ills ) .
