striated, the striation decussated by close, finely impressed, longi-

 conoid, apex obtuse, suture deep ; whorls 5, rounded, slowly 

 increasing in size, the last rounded at the periphery and beneath ;

Near S. srimani, but the spiral sculpture is different and much

 Khasi Hills rather larger, from 5 to 5| nun. in diameter. 



[Dr. Blanford placed this species in Macroclilamys with doubt ;. 

 I retain it in Sitala. The animal is unknown.]
