357 
Corals from the China Sea. 
of these there are 7 species belonging to genera which may 
properly be considered deep-water corals rather than reef- 
builders ; these are Desmophyllum , Flabellum , Cyathohelia , 
Lithophyllia , Tridacophyllia , and Balanophyllia . The 
remaining 12 species of reef-corals living at these unusual 
depths belong to the following genera : — Stylophora , 1 sp. ; 
Faria, 1 sp. at 45 fath. ; Pavonia, 1 sp. ; Leptoseris , 1 sp. ; 
Phyllastrcea, 1 sp. ; Psammocora, 1 sp. ; Mon tip or a, 3 spp. (one 
of these at 44 fath.) ; Rhodarcea, 1 sp. ; and Alveopora , 2 spp. 
It is also worthy of mention that five new species of the 
genus Madrepora — a genus usually limited to depths of under 
10 fathoms — were found living at depths of 20 to 27 fathoms 
both on the Tizard and Macclesfield Banks. 
Of the 18 species found growing on the coral-head inside 
the lagoon 15 were not found elsewhere, and the diver 
reported that the bottom looked different. This is rather a 
remarkable fact, considering the size of the lagoon and the 
depth of water.
