1. Teochoctathus corbicula, Duncan. Plate VII, Figs. 12-14. 



The corallum is short in height, long and narrow in its very deep and elliptical 

 calice, rounded at the base, generally compressed, and the calicular margins are curved 

 inwardly at the sides. 



There is a granular and rather indistinct epitheca ; but the costae are visible at the 

 calicular margin and for some distance down ; they are numerous above, subequal, and 

 minutely granular. 



The septa are numerous and crowded at the rather broad margin ; a few are 

 slightly exsert, and they are very unequal in size and length. They dip down close 

 to the thick wall, and extend very slightly into the calice, and the larger pass along 

 the base of the very deep calicular fossa to the long elliptical and largely developed 

 trabecular columella. The septa are alternately large and small ; and the smaller are 

 separated by a longer, which either does not reach far down, or is attached to the 

 columella, by a paliform continuation. There are more than five cycles of septa ; 

 the laminae are thin, often wavy and distinctly granular. 



Length of the corallum -J inch ; length of the calice Ixo inch. 



Breadth of the calice -g- inch ; depth of the calice ^ inch. 



Locality. Hills'east of Lynyan, Kanikot group. Survey-number G -f-lf-
