angui liens is 
Septa in general thin and distant, thicker over the 
arches of the collines. The number to the cm. is 8 to 12, the 
s suae as for the costae. There are no clearly distinguishable 
cycles, the septa are subequal or alternate irregularly in 
size. The interseptal loculi are usually about tv/ice the width 
of the septa. The septal margins are quite regularly serrate- 
ly dentate, about as in iiaeandra ( Maniclna ) areolata (Linn.). 
Kndothecal dissepiments well developed, thin; exotheca present. 
Columella poorly developed, all but absent, formed by 
the very loose junction of processes from the ends of a few 
septa. The calicinal centers are indicated by the direction of 
the septa and the lateral lobes of the valleys.
