upper whorls is strong and rather distant, much closer and ranch 

 stronger next ihe ovate sutural tube ; about six to seven cosUe 

 between the tube and peristome, thei-e are from 2 to 3 well marked 

 costtu on the very slightly swollen part of the whorl. There are 

 about a dozen examples, and from PiknaiHill, 2602 B.M.,about8. 



Altc^its (Cyclortx) gkaphicus, W. Blf., var. dihingensts. 



No. 2748 B.M, was found on Angaoluo Peak, Kaga Hills, and one 

 examj)le, No. 295. 12.iv.l6, occurred in Colonel Jieddome's collection 

 from the Naga Hills, exact locality not mentioned ; as Mr. Muspratt 

 was the collector it was probably somewhere on the eastern side.

 swollen ; aperture circular ; peristome double, both thin ; colu-

Comparing this with A. granum, it has for its size much closer 

 costulation. It is more narrowly umbilicate than A. burraile^isis, 

 which is a much smaller shell.
