Montipora verrilli VAUGHAN , 1907
1907. VAUGHAN. 168; pIs. 63/2. 2a. b ;64/ 1. l a.
19H. WELLS, 438;pls. 145 /3. 5; 148/ 1. 2; 179/4.
1980. HEAD. 149. 447.
This is the first Red Sea record.
Another species, MOlltipora granulata BERNARD,. 1897, is listed by. LOYA & S.LOBODKIN (1971 :
123) and MERGN ER & SCHUHMACHER ( 1974: 265) In their checklists wIthout descnptlons and figures.
HEAD (t 980: 447 ) assumes that M. gramdata (not granulosa) is a junior synonym of EHRE BERG's
M. stilosa.
LOYA & SLOBO DKIN (197 1: 123) list also M. composita CROSSLAND (1952: 195; pIs. 2811 , 5;
29/1,3,4). HEAD supposes (1980) that this species is close to M. verrilli VAUGHAN .

Family Agariciidae GRAY , 1847
Synopsis of the genera of Agariciidae considered herein:
A. Corallum encrusting, foliaceous, columnar or ramose, uni- or bifacial. Corallite centres well distinct.
Septo-costae confluent between centres with serrated or beaded edges. Columella styliform. Thecal
wall usually not projecting. . .................... . ................. .. . . .... . ... Pavona
B. Corallum encrusting or foliaceous, unifacial. Corallites distinct, wall projecting on one side of the
calyx. Septo-costae confluent between calices. A central mother calyx often visible around which
secondary calices are arranged ... . . . ...... ... . .. . .......... . .. .. .. .......... . Leptoseris
C. Corallum encrusting, unifacial, hydnophoroid with long valleys and collines. Columella lamellar.
Septa close together, continuous over the collines ................ .. . . .. ........ . . Pacbyseris
D. Corallum encrusting or massive. Corallites polygonal, deep, wall acute. Septa of higher cycles join
those of lower ones, before the latter unite with a central styliform columella situated at the centre
of a small circular axial fossa ........... . ...... . ......... . ....... . .. .. . ... Gardineroseris
Genus Pavona LAMARCK, 180 I
