Oorallum arborescent and subflabellate, irregularly dichotomous, 

 slender, finely striated, with minute pores in the stria 1 . Calicles sub- 

 pedicellate, of a larger diameter than the stern, all facing to one side. 

 Septa twelve to sixteen, not extending far into the calicle. Columella 

 not visible. The lower border of the disklike expansion of the calicle 

 prolonged into a lip folded over so as to hide the fossa. Some of 

 the calicles inflated and globular, perhaps from the presence of para- 

 sites.

 flattened. Sm-face finely and sharply granular, porous. Branchlets 

 thick and obtuse. Calicles irregularly but densely distributed on one 

 surface of the branches, obsolete on the main trunk. Small ampulla 1 

 abundant between the calicles on the younger brandies. Calicles 

 slightly prominent, fossa deep, columella large, spherical, hirsute, deep- 

 ly immersed. Septa from seven to ten, generally eight. Interseptal 

 chambers comparatively large, with very distinct hirsute tertiary septa 

 enclosed, giving to the whole when magnified the appearance of a
