An interesting small form of tlie preceding, witli shorter 

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

 Burmese forms brought back by Dr. Anderson and almost 

 induces me to specifically separate from P. dissimilis, the foi-nis 

 hereafter recorded as vms. lielicifonnis, viridis and decussatula, 

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

 as restricted ?
