u I am indebted to Dr. Westerlund for Pupa tumida , of 
which I find a specimen in my collection named V. pusilla , 
var. I am not sure that it is more than a dwarf variety or 
form of V. pusilla . The two specimens sent by Dr. Wester- 
lund differ from each other in the number of teeth, one speci- 
men having five and the other seven teeth. He describes 
V. tumida as ‘ 6-dentata ’ and V. pusilla as i 6-8-dentata.’ ”
