This zone is then normal, with three forms extra and six forms 

 missing. Of the extra forms (106), listed in Goldschmidt's Winkel- 

 tabellen, was observed as one narrow and etched face. The form 

 308, first described by Gorgey and Goldschmidt from this locality, 

 was many times confirmed and is well established. (12.0.25), 

 admittedly vicinal, may be ignored. The new form (403) in this 

 zone is normal, and being entirely probable may be regarded as 

 established, although it was seen as only a single narrow face.
