species with O. butltri described further on. The form from the 

 Luka Valley is a tumid departure from the type figured. One 

 specimen measures: alt. 0'75 [=19 mm.), major diam. O38 inch 

 [ = 9*25 mm.], another 0*65 [=16-25 mm.], major diam. 0-35 inch 

 [=9 mm.]. 



" I look on all these species as properly varieties, and G. crassi- 

 labris, very abundant in all the grass country of the Khasi Hills, 

 may be taken as the type ; a difference in elevation and conditions 

 of habitat, from damp dark forest to hot grassy slopes, having 

 produced modifications of form." 



Pilsbry points out that in G. illustris the embryonic ivhorls are 

 closely and finely striate vertically as in G. notigena and that hence 

 it has no affinity to G. crassilabris. He continues : " It is a much 

 less robust shell and less polished ; and on the last whorl there 

 are traces of fine spiral striation, as shown in fig. 13. The sculp- 

 ture of the later whorls is irregular ; there seem to be unequally 

 separated grooves, with finer striae and grooves in the intervals, 

 but quite unequally developed. The suture is crenulate. On the 

 last whorl or two some traces of spiral striae appear in places. 

 The outer lip is a little sinuous, being retracted above ; it is 

 moderately thickened or obtuse." 



Beddome was unable to distinguish this species in any way from 

 G. facula, but the latter lias the whorls much more closely coiled. 



A specimen from N. Cachar, in the Beddome collection, com- 

 posed of seven whorls, measures only 16 mm. in length and 7mm. 

 in diameter.
