The corallum is short, with a large base of attachment and a large circular, very- 

 open, shallow calice. The pali form a very distinct raised ring around a very small 

 columella, on which a few papillae may be seen. The septa are unequal in size, much 

 thickest near the margin, and the primaries and secondaries resemble each other, pass 

 far inwards and have pali before them ; the next orders are not so large, and the higher 

 orders pass but a short distance inwards. There are about 72 septa, and about 20 

 shorter stout dentate pali. The costse are well developed, are alternately large and 

 small, and the epitheca is in bands. 



Height of the corallum yq inch. Breadth of calice -yq inch. Breadth of base ^ inch.

1. TEOCHOCYATHUS Gajensis, Duncan. Plate XXIII, Figs. 3, 4. 



The corallum has a flat elliptical base, from which the sides slope with concave 

 curves to a widely open, oval-elliptical, slightly bilobate calice, whose minor axis is on a 

 higher plane than the major. The cpstee are numerous, irregularly arranged, sub- 

 equal and distinct to the base. The large septa are about 48 in number, and many 

 minute rudimentary ones exist. The larger septa are stout, and the pali are small but 

 distinct, those before the larger septa being the largest.
