me that there is a certain amount of difference in the different shells. ‘ The 
columnellar lobe is as in A, perakensis^ Fult.* ; it is evidently closely allied to 
that species, only differing in form. It is figured by Pilsbry^ as a form of 
leucoxanthus^ which he considers a variety of aureus^ Martyn. In my mono- 
graph I consider leucoxanthus as a variety of perversus^ and I think the presence 
of a columnellar lobe in perakensis, and the present shells from Jalor, to be 
sufficient to separate them from leucoxanthus. I should propose calling your 
perakensis^ var. or subspecies
