Azooxanthellate Scleractinia of Western Australia 
381 
developed papillose columella consisting of many 
small interconnected irregularly shaped elements. 
Remarks 
Among the approximately 19 Recent species of 
Paracyathus (Best et al. 1995), only P. fiilvus has SI 
larger than its S2 and a strongly encrusting base. It 
is not possible to confirm this identification without 
having examined the holotype in the Calcutta 
Museum, and thus this identification is considered 
tentative. This is believed to be the only report of P. 
fulvus subsequent to its original description. 
Folkeson (1919) also reported Paracyathus 
•profundus Duncan, 1889 from the same station as 
above, but re-examination of this specimen reveals 
that it has deteriorated significantly since originally 
reported. What remains appears to be the corallum 
of a rhizangiid. 
Distribution 
Western Australia: continental slope of 
northwestern coast off Dampier Land; 350-433 m. 
Elsewhere: Persian Gulf; depth unknown 
(telegraph cable).
