260 CATALOGUE OF THE FOSSILS OF THE PERMIAN SYSTEM 
Portions of the column of a species of Encrinite are frequently 
very abundant at Humbleton, but the cap very rarely occurs. The 
column is not quite cylindrical, some of the joints being more 
prominent than others. The articulating surface of the joints is 
strongly radiated. The outer surface of the stem is covered 
with fine waved concentric lines which are easily overlooked.

1. C. QUADRIFIDA, 7. s. 
Coral simple, with a nearly cylindrical tubular stem ; 
cup deep, gradually tapering, extending nearly the whole 
length of the coral, divided by three or four equally dis- 
tant, narrow, lamelle; surface longitudinally striated 
with distinct annular rings of growth. 
In Magnesian-limestone; rare. Humbleton Hill. 
The cup of this coral is very deep, and tapers gradually from 
the bottom to the top of the stem, where the edge is extremely 
thin. Internally it is divided by four thin plates or lamella, 
which are at equal distances from each other. The outer sur- 
face is striated or furrowed longitudinally, and the periods of 
growth are marked by distinct annular rings. In general form 
it slightly resembles some species of Turbinolopsis, but differs in 
having a deeper cup, and less solid stem.
