p. 225) and to A. stranynlams, Hutton. Inferior in size to the 

 former, it is easily distinguished by its sculpture and by the 

 peculiar development of the outer lip at its insertion and base, 

 while the narrow columellar lip gives an appearance of artificial 

 truncation to the peristome at that part. In the variety the 

 internal lip is not developed. The margins of the whorls in the 

 operculum are not conspicuously raised as in A. umbonalis.'"

I have"^ seen two specimens in the above collection which are 

 smaller than the usual typical form, and though quite similar in 

 shape, show a decided tendency to erenulation on the outer margin 

 of the peristome ; a similar tendency I have observed iu other 



species. , o • ■ 



Some specimens from Teria Ghat are as much as 8 mm. in major 



diameter; it varies much in size even from this locality, fully grown 



examples' being only 6 mm. From some places all are small, and 



G Nevill distinguished them as var. minor. 



Prom %wuk, at the foot of the Garo Hills, the form differs 



considerably iu having a tendency to a crenulate peristome which 



I figure and describe.

Original descrij^tion :—" HheW pale corneous or amber, finely 

 and evenly costulated throughout. Spire depressed, apex blunt

 little swollen, slightly constricted, with a single low ridge close 

 behind the aperture', the constriction smooth and very finely 

 striated. Sutural tube very short. Aperture shghtly oblique, 

 circular ; peristome single, simple, continuous, moderately thick-

"This is anolher species of the short-sutural- tubed section of 

 Alycceus, of which A. khasiacus (vide pi. iii. fig. 4, J. A. S. 

 Bengal, vol. si. pt. 2, 1871) is a good type. The general and 

 distinct costulation from constriction to apex, particularly the form 

 of constriction and mouth, mark it as^ a good species. It is more 

 openly umbilicated than A. Jchasiacus."
