An interesting small form of tlie preceding, with, shorter 

 and less produced spire ; it is quite unlike all the other Upper 

 Burmese forms brought back by Dr. Anderson and almost 

 induces me to specifically separate from P. dissimilis, the forms 

 hereafter recorded as vars. heliciformis, viridis and decussatula, 

 in which case this form would be a variety of true P. dissimilis 

 as restricted ?
