 Deposits of Bind above the Bcmikot Series.

 the Khirthar series or the base of the Nari series.

1. Teochocyathus nummuliticus, Duncan. Plate IV, Figs. 1-3. 



The corallum is cyclolitoid in shape, circular in outline, depressed centrally at 

 the axial space, slightly convex to the margin, very short, and either very slightly 

 convex inferiorly or concave. The base is attached to a small Nummulite, and has a 

 delicate epitheca, through which the costse can be seen. The costae are straight, 

 numerous, unequal, and many reach the point of attachment, and there are three 

 smaller ones between each pair of the longer. 



The edge of the calice is perpendicular for a very short distance, and there the
