Remarks 
Grygier and Cairns (1997) illustrated several 
extremely enlarged, highly modified corallites of 
Western Australian M. oculata that were caused by 
the infestation of petrarcid ascothoracidan 
crustaceans. The 12 Western Australian records 
cited by Grygier and Caims (1997) are reiterated 
above, and constitute an infestation rate of 39.4% 
(13/33 lots listed above marked with an asterisk) 
of the lots known from Western Australia. 
However, even corallites not affected by parasites 
show great variation in calicular features. Some 
coralla have a deep fossa and no pali or columella, 
whereas others have a shallow fossa and well- 
developed P2 and columella (Figure If). Several 
coralla were noted to have asymmetrically 
developed P2, bearing 2 or 3 enlarged P2, the other 
P2 being rudimentary (Figure li). Still another 
corallum possessed several corallites in which the 
septal and columellar elements had been reduced 
to a thicket of elongate spines (Figure lg-h). Those 
coralla in which the P2 and columella are well 
developed resemble the genus Sclerhelia Milne 
Edwards and Haime, 1850a; however, the P2 and 
columella are much more robust in that genus. 
Nonetheless, a revision of the Oculinidae may lead 
to the synonymy of Sclerhelia with Madrepora or, 
conversely, the splitting of the Madrepora oculata 
into several species. 
Distribution 
Western Australia: continental slope of 
northwestern coast from Cartier Island to 
southwest of Rowley Shoals; 304-544 m, usually on 
a soft (mud) substrate. Elsewhere: virtually 
cosmopolitan, except for continental Antarctica 
and southern Australia; 15-1500 m (Cairns and 
Zibrowius 1997).

New Record 
East side Thomas Island, Esperance, 9-12 m (back 
of cave), 6 III 1977, 1 large colony, WAM 623-79. 
Remarks 
This colony differs from those previously 
reported in having a completely white corallum, 
the others having a tan corallum with dark brown 
corallites. When alive, however, this colony was 
reported to have brown polyps. The Esperance 
specimen is the largest known corallum, measuring 
15 cm tall and having a massive base 5.5 cm in 
diameter. 
Distribution 
Western Australia: Recherche Archipelago 
(Veron 1986) and Esperance; 12-40 m. Elsewhere: 
western Pacific from Japan through Indonesia; 13- 
366 m (Caims and Zibrowius 1997).
