TERTIARY CORALS. 59 
pali are small and lobular, and appear to be placed before all the septa except those of the 
fourth cycle. 
The coste are distinct from the base upwards, are subequal, slightly prominent, and 
granular. The intercostal grooves are very distinct. Near the calicular margin the costz 
are often found projecting outwards and becoming exsert.

The corallum is short and broad, and its base is nearly as broad as the calice. 
The wall is thin. 
The calice is irregularly elliptical, and its long axis is on a lower plane than the 
short axis. The margin is sharp and irregular, the fossa is not deep, and the columella 
does not occupy very much space. 
The septa are slender, crowded, unequal, granular, and slightly exsert. There are 
six systems, and the arrangement of the cycles is very irregular. There are two systems 
in which the septa of five cycles are complete, two in which they are incomplete, and two 
presenting septa of four cycles only. The primary septa are readily distinguished, 
and all the septa are long and often flexuous. The tertiary septa join the secondary 
in some systems. 
The pali are present before all the septa, except those of the last cycle. 
The columella is spongy. 
The costa are thin, sharp, laminate, and project; they are often slightly flexuous, 
and their free margin is moniliform. The intercostal spaces are wide and deep. 
There are traces both of exotheca and of endotheca. 
Height of corallum 3ths inch. Great diameter of calice ‘ths inch.

These Paracyathi are closely allied to the species already described from the London 
Clay, by MM. Milne-Edwards and J. Haime. 
P. Harmer differs, however from its nearest ally, P. crassus, in its septal arrangement, 
in the sharpness and ornamentation of the costa, and in the size of the intercostal 
spaces. 
P. cylindricus has some resemblance to some varieties of P. caryophyllus, but the 
septal arrangement, the small columella, and the very small pali, distinguish it.
