The relative thickness and the rugose aspect of the young indi- 

 viduals serve to confirm the reference of the specimens to this form.

The thinness of this form, its highly-curved septa, rapidly- 

 expanding whorls, small central chamber, and constantly small 

 size seem to identify it with the above species from the Hala range 

 of North-Western India, 



Locality. — A mile south-east of Magyisan (Minbu district).
