hemispherical specimen, showing the 

 large rhomboidal cells over tlie dome 

 and the narrower crowded cells on the 

 larger vertical portion, the latter being

 presence of crystalline matter adhering to most of the speci- 

 mens. Species easily distinguished by its small size and dome 

 form, except from H, hemisphericus.HsilUoi Wisconsin, which 

 however has much larger cells and grows much larger; no B,
