circular, aiigulatc above, and much exjianded ; peristome douWe, 

 inner continuous, outer much expanded but not reflected. 



Size : major diam, 3"5 ; alt. axis I'G mm. 



Five of this pretty form are in the collection ; although very 

 close to A. tJieobaldi, it is easily distinguishable in its size, general 

 form, and sculpture. In another tiibe four other specimens were 

 found (No. 2G63) from North Khasi. 



In 1871 1 gave in J.A.S.B. pi. v. fig. 4 (reproduced Plate CXLIII. 

 fig. 9) a figure of A. (Diori/.v) urnula, 13s., but with neither a de- 

 scription nor notice — its habitit was Marangsip Peak in the South 

 Jaintia Hills. A close comparison of shells from this locality with 

 Darjiling typical shells shows considerable difference, sufficient for 

 record. I propose to distiuguish it as Ahicwns {Dioryx) urnula, Ps., 

 var. pisum, and with it I include the Dioryx from Nongjinghi 

 (Xo. 252G), also (No. 2524) from the Eastern 'Garo Hills. 



This variety may be known by a more globose shape and a more 

 depressed spire than in the type species. 



Altc j:us (Dioryx) urnula, var. pistjm. (Plate CLIII. figs. 3, 3 a.) 



Locality. Nongjinghi Trigonometrical Station, 4563 feet, Jaintia 

 Hills [Gochvin-Austen). 



Shell globosely conoid ; colour whitish to pale pink ochraceous ; 

 spire moderately high, apex blunt : suture well impressed, the 

 tube moderately long; whorls 4, the last very tumid; aperture 

 circular; peristome moderatelj' thickened; operculum multispiral, 

 central portion rather raised above the marginal whorls. 



The specimens from Marangsip Peak are most richly coloured in 

 tints of pink and ochre.
