Remarks 
Vaughan and Wells (1943) and Wells (1956) 
defined the suborder Dendrophylliina as having 
porous septa and theca (a synapticulotheca), and, 
believing Psatnmoseris hemisphaerica to have both 
porous septa and costae, placed it as a genus in 
that suborder. However, examination of the types 
of H. hemisphaerica (BMNH) and Spongiocyathus 
typus (SMNH 4753-56) reveals that, whereas their 
septa are highly porous, their costae and theca are 
solid, much like that of a turbinoliid. I therefore 
agree with Hoeksema and Best (1991) that 
Psammoseris hemisphaerica must be returned to the 
Caryophylliidae and the genus Psatnmoseris placed 
as a junior synonym of Heterocyathus. It is ironic 
that Folkeson (1919) correctly placed Psammoseris 
in synonymy with Heterocyathus , but did not realize 
that his new genus Spongiocyathus, which he 
considered as a caryophylliid, was a junior 
synonym of Heterocyathus as well, based on the 
same species: Heterocyathus hemisphaericus. 
Heterocyathus hemisphaericus differs from H. 
aequicostatus in having: 48 highly porous septa, only 
the S4 of H. aequicostatus being slightly porous, and 
usually numbering more than 48; very thick (i.e., 
0.9 mm vs 0.15 mm wide) SI; costae that are much 
wider than the intercostae, composed of elongate 
spines that originate directly from the theca, not 
costae that are equal in width to the intercostae 
and composed of granules that ornament costal 
ridges, as in H. aequicostatus; sipunculid efferent 
pores and canals opening only on the base of the 
corallum, those of H. aequicostatus opening on the 
base and edges of the corallum.
