name for rhis species. Bur VAUGHAN (1918) separared rhem and was followed by WljSMAN-BEST (1972 ),
PILLAI & SCHEER (1976) and VERON , PICHON & WljSMAN-BEST (1977 ).
ESPER 'S rype of M. pelltagona as well as EHRE BERG'S rype of A. melieenml are lost. Therefore
derails in rhe srrucrure of rhe rwo corals probably never can be compared wirh each orher. MA TTHAI
(1914) knew EHRENBERG's rype and has figured ir (pI. 36, fig . 4). Bur he , roo, did nor have ESPER 's
M. pentagona on hand.
We follow VAUGHAN (19 18) wirh some doubr and keep rhe rwo species separare. Bur we can nor
incorporare Favites melieerum inro rhe presenr work , because rhe species was nor found in rhe Red Sea.
Also EHRENBERG'S rype is from an unknown localiry.
Genus Goniastrea MILNE EDWARDS and HAIME, 1848
Type species: Astrearetiformis LAMARCK , 1816.
G e n e ric c h a r a c r e r s: Encrusring, massive , cerioid or meand ering. Wall solid. Sepra of equal
rhickness ar rhe wall , broader below wirh a shelf and conspicuous paliform lobes. Columella rrabecular.
Asexual reproducrion by mono- ro rrisromodaeal inrrarenracular budding.
Many species of rhis genus are described from rhe Indo-Pacific. VERON, PICHON & WljSMAN-BEST
(1977 ) recognized seven species from Easr Ausrralia which cover all rhe Indo-Pacific forms . However, rhe
presenr aurhors rhink rhar rhere are nor more rhan rhree valid species in rhe genus . We consider G. solida
(= G. edwards i) and G. retiformis as one ; all rhe species described in lirerarure wirh mono-, di- ro rrisromodaeal
forms and larger calices rhan in retifonnis as anorher, viz G. peetillata, and possibly a rhird wirh
meandering valleys, viz G. allstraiensis.
G. palauensis Y ABE , SUGIYAMA and EGUCHI, 1936, is in all probabiliry a Favites.
