This species is the same as Duncan Stylophora af finis var. 2 
(Quart. Jour. Geol. Soc, London, vol. xx , p. 27). The type specimen 
of the variety is No. 12S05. There are two other specimens that bear 
no number. Sp. No, 12905 is photographed. Note especially that the 
upper lip of the calice may be more prominent than the lower. This 
coral is very close to Stylophora af f inis .
