Original description: — "Shell deeply and promiuently umbili- 

 cated, turbinato-globose, glabrous or subglabrous, epidermis of a 

 pale yellowish-brown colour, with oblique vei'tical dark chestnut- 

 coloured bands and a minute vertical striation, white beneath the 

 epidermis; spire conical, apex subacute; whorls five or six, the 

 lowest smooth in its upper half near the suture, in the region of 

 the periphery surrounded with three rather prominent carinations 

 with a smooth space between them and the umbilical region, the 

 penultimate and antepenultimate with generally two less promi- 

 nent lines or ribs; lowest whorl cylindrieal, slightly descending 

 with an inconspicuous swelling followed by a slight contraction 

 just in front of the reflexed peristome; the umbilicus furnished 

 with very prominent spiral ribs up to the very apex of the shell ; 

 aperture a little obli(iue, subcircular ; peristome lialf-double ; the 

 inner lip dilated and much angled on its outer margin, small and 

 continuous round the inner margin, outer lip irregularly angled 

 on its outer margin, and much dilated at the inner basal 

 n)argin, where it suddenly terminates, not being continued 

 round the inner portion of the aperture; operculum externally 

 milky white, shelly, papillifonn, smooth, ilattened at the apex, 

 whei'e it is furnished with a small circular aperture, inner layer 

 membranaceous, slightly concave externally, with a central 

 diaphanous nucleus, multispiral, the edges of the \\horls raised: 

 height of shell j^ inch [4'5 mm.], the greatest diameter 

 equalliTig the height." 



I/(d>. India: South Canara (}hats, 2000-3000 ft. elevation 

 (Beddome) ; Wynaad (Fairbank). 



"The operculum is an exaggerated form of that of the typical 

 Ct/alhojiuma Jilocinclum, the margins of the outer shelly layers are 

 arched over and almost meet in the centre, forming a papilla with 

 only a small hole in the centre." {Beddome.)
