Campophyllum torquium Owen. 
‘‘Corallum simple, attaining a rather large size, elongate conical, 
and often variously geniculated or bent when two or three inches 
in length, but becoming nearly straight, subcylindrical, and con- 
siderably elongated in the largerhalf of adult individuals. Ep- 
itheca thin with small encircling wrinkles and strong undulations 
of growth, showing no traces of the septal coste when unabraided, 
but, where even slightly worn, exposing the regularly disposed 
septa and thin intervening dissepiments distinctly. Calice cir- 
cular or shghtly oval, comparatively shallow, with thin margins, 
from which its sides slope rather steeply inward for some distance 
and then descend very abruptly into a deeper, narrow, central 
depression; provided at the outer side of the general curve of the 
corallum with a moderately distinct septal fossula, formed by the 
shortening of one of the primary septa, and the bending down of 
the tabule at that point. Principal septa from 30 to 48, extend- 
ing from about one-half to two-thirds the distance from the exter- 
ior toward the center, stout and usually straight inside of the outer 
vessicular zone, but becoming distinctly more attenuated (as seen 
in transverse sections) and somewhat curved or a little flexuous in 
crossing the vesicular area, where they alternate with an equal 
number of very short, thin ones; tabula very wide or occupying 
about two-thirds the entire breadth as seen in longitudinal sections, 
and passing nearly hortizontally across with a more or less upward 
arching; dissepiments thin and forming numerous obliquely as- 
-cending, small vesicles, in transverse sections seen to pass .across
