Note. Names printed in black faced type are of those minerals which 

 because of their definite characters and the completeness of their description 

 seem to warrant acceptance as definite species. Names printed in light-face 

 capitals are of incompletely described minerals which at present are more or 

 less doubtful in character. Variety names are printed in light-face lower 

 ease letters.
