In some respects allied to M. spiyiata, G. -Austen,' from the Kopili 

 River, North Cachar Hills. That species is, however, much larger, 

 bears a double row of tubercles, and lacks the two spiral lirae and fine 

 wavy striae above the angle on the whorls. Moreover, the spiny 

 tubercles readily distinguish it from M. Eelantanensis.
