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

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

 specimen measures: alt. OTo [=19 mm.), major diam. 0-33 inch 

 [ = 9-25 mm.], another 0-G5 [=16-25 mm, J, major diam. 0-35 inch 

 [=9 mm.]. 



•' I look on all these species as properly vai'ieties, and G. crassi- 

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

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

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

 produretl modifications of form." 



Pilsbry points out that in G. illustris the emhri/onic tvliorh are 

 closehj and finelij striate vertically as in G. notigena and that hence 

 it has no affinity to G. crassilahris. He coutinues : "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- 

 tui'e of the later whorls is irregular; there seem to be unequally 

 .separated grooves, with finer strife and grooves in the intervals, 

 but quite unequally developf^l. The suture is crenulate. On the 

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

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

 moderately thickened or obtuse." 



Beddome v.as unable to distinguish this species in any way from 

 G. facnhi, but the latter has the wliorls much more closely coiled. 



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

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

 in diameter.
