CARYOPHYLLIA CEA. 
TURBINOLIADAL 
THE WINGED CUP-CORAL. 
Paracyaflius lyteropns:, 
(r'p. nov.) 
Plate X. Fly. 7. 
Specific Character. Plates in four imperfect cycles ; calice circular ; 
ribs very salient, dilating into wings below ; height less than half the 
diameter. 
GENERAL DESCRIPTION. 
Corallam. Cylindrical, adhering by the entire breadth ; height less 
than half the diameter. 
Ribs. Thin, nearly straight, sub-equal, separated by intercostal spaces 
about thrice their width, very salient throughout, but from the middle 
do^vnwa^d developing into triangular buttresses, the long lower edges of 
which are adherent to the support, so that the area inclosed by their 
points is far wider than that inclosed by the wall : their whole surface, as 
well as that of the intercostal spaces, has a slightly carious, but glossy 
appearance, not exactly granular. 
Calice, Circular, shallow ; the margin in the same plane. 
Plates. Forming four cycles and six equal systems, those of the fourth 
cycle wanting in half of each system. They are wide apart, being separated 
by twice or thrice their own thickness, thin, salient, but unequally so, 
some of the primaries and secondaries rising to twice the height, above the 
waU, of the tertiaries, but others are more nearly equal ; their planes are 
more or less waved, and their surfaces set with scattered blunt eminences : 
upper edge truncate, nearly horizontal, but slightly declining inwards, and 
rising with an abrupt blunt point at the inner edge, which then descends 
perpendicularly. 
Columella. A single flexuous plate, united 
below to the palules. 
Palules. Distinct, united to the inner edges 
of the primary and secondary plates, and to 
some (not all) of the tertiary : they are thick, 
very sinuous, their surfaces set with rounded 
eminences, and their upper edges much 
lol>ed ; they are united by their inner edges 
into an iixegular horizontal platform, out of the centre of which rises the 
columella.
